KR> Landing gear

[S B]

Owen,

I used a cut-in-four Corvette leaf spring for my tailwheel spring, it seems to 
be well adapted for that use. However, I consider it is not thick and large 
enough for a KR-2S main gear leg.
By the way, the Corvette leaf spring is fiberglass and not carbon fiber.

Regards,

Stefan Balatchev

I would be tempted to look at the carbon fiber leaf springs from a junked very 
low milage Corvette or NOS. The Corvette carbon springs are light, high 
modulus, and remarkably cheap. I think they can be machined down to provide a 
lighter spring rate if thats desired.

Hi Bill,

With the hesitation that (in my sometimes bitter, sometimes sweet experience) 
any deviation from the well trodden path leads to excessive completion delays 
and unpredictable results, this is after all ?experimental? aviation. 

The project I took on already had gear, but if I was at that stage I would be 
tempted to look at the carbon fiber leaf springs from a junked very low milage 
Corvette or NOS.  The Corvette carbon springs are light, high modulus, and 
remarkably cheap. I think they can be machined down to provide a lighter spring 
rate if thats desired.  

On the other hand, the new Sonex gear is Titanium and they certainly know about 
these carbon springs, so there may very well be a good reason they wouldn?t 
work well.

KR> Landing Gear legs

[Stef den Boer]

Hi Stan,

We use the old type landing gear. It is all 7075T6 alluminium. 3 brackets aft of
the fwd spar. I think this one give you more propclearce.

I think the aluminium gear is more weight than the new glass system.

On my website you see 3 KR2s. The PH-OMI and the PH-MIJ uses the old aluminium.
The PH- KRS is using the new system. At the page flight controlls you see the 3
brackets.

The Diehl gear consists of two cast aluminum spar brackets, two lower 
axle attach brackets, and two Scotchply fiberglass gear legs connecting 
the two.

I don't have personal experience with the aluminum gear legs, which is 
why I haven't piped up on this until now.  But I do know somebody that 
had it, Troy Petteway.  I believe his plane used the normal spar 
castings, but he used aluminum gear legs. He got them from Steve 
Bennett.  That way there's no bending involved.  He did manage to break 
one in an engine-out landing on curvy road, but I have also broken a 
Scotchply gear in a similar situation.  My first landing was 5.5g's, so 
they were already proven to exceed the design parameters.

  It obviously works, but I wouldn't want to put a continuous aluminum 
gear leg under my plane unless I'd built a bunch of them and they tested 
with no failures (think minimum bend radius stuff), or somebody else had 
done the same.  Grove Aircraft makes bent aluminum gear that is one 
piece, and I'm pretty sure Rand Robinson sold something similar, if not 
exactly that. See http://www.groveaircraft.com/landing_gear.html for 
plenty of options. They also sell aluminum gear legs that could be used 
with spar brackets.

Troy's opinion was that the aluminum was more springy than the 
Scotchply, which has some slight amount more damping. That might have 
been a function of loading though.  That's all I can offer you on that 
comparison...no real facts.

See http://www.n56ml.com/kgear.html for more on what Diehl gear looks 
like.  nvAero sells them now, as well as Scotchply gear legs.

KR> Landing Gear legs

[Global Solutions]

Hi Folks
I was looking in to the landing gear for a Kr2S. The boat is going to be 
6" wider then the stock plans.
I was looking at the NVaero site and they have the castings for the Deli 
gear which because they have no picture I am guessing I would still need 
to make the actual legs. they also do not specify if the castings they 
sell are priced each or for the pair.
I then came across this which is made from Material: 7075-T6 Aluminum
KR2 One Piece Landing Gear
The airport I have access to for the moment is a grass strip and I was 
thinking the aluminum may act as a bit of a shock suppressor and may be 
lighter then the wood/glass that others have used.
Would I be ahead to bend something like this in the press brake or go 
the Deli Gear route?

Also I was thinking of going with MATCO brakes as per NVAERO or am I 
better off with Cleveland or some other brand. I also noted on Mark 
Landfords site that he played with wheel sizes. What is the overall 
consences with respect to tire size?

Thanks

Seeing no replies to your question I'll offer my "opinion". If you
are building a tail dragger I'd leave them full length. A nose
dragger may require you to shorten them to match the nose gear. If
you expect your KR to come in around the 700-750 pound range, many do
now days, I'd leave them original thickness and cut them to the
contour of the Diehl legs. I've got 30" Diehl gear legs and I
thickened them a bit. That's my "opinion" based on my
experience. Jeff Scott has the only other set of 30" inch legs and I
don't know if he "thickened" them or not. Mine seemed to be a bit
soft with two people , early in the build process.

My gear legs have the micro with soda straws formed into the leading and 
trailing edges for brake lines and a wrap of BID glass to finish.  I've been 
pounding this poor plane on the ground relentlessly for over 1100 hours, 
usually at or near 1200#, and have never had any issues related to the landing 
gear.  Mine are a bit softer than many others, but that doesn't seem to affect 
them adversely. Soft gear makes for smooth landings.  :o)

Like Larry, I think I would taper them to match the contour of the Diehl gear, 
give them a wrap with glass to finish and call it close enough.

I finished mine using a piece of foam (approx 1") on lead and trail 
edge.  I hogged out a channel on the lead edge before attaching for 
the brake line.  I rounded the lead edge foam and tapered the trail 
edge and wrapped the entire thing with a layer of glass.  Not a great 
photo but if you zoom in a bit you can see the 
gear.  https://dl.dropboxusercontent.com/u/32133949/100_5553.JPG

This photo shows the brake line running through the landing light 
area and then down the lead edge of the 
leg.  http://myplace.frontier.com/~flesner/02092583.jpg   If I ever 
need to get to the gear leg attach bracket I can cut out the foam on 
the back side of this opening.  I located the light in that area for 
that purpose but a better spot for the light is outside the prop arc 
unless the back side of the prop is painted black.  If it's not black 
you see a giant prop reflection at night and when else do you need 
the light, unless of course you have flashing landing lights for 
daylight recognition.  That's one of those "don't ask me how I know" deals.

KR> Landing gear question

[Sid Wood]

Mark,
I used the same Grumman gear leg blanks you describe.  I ran them through my 
wood power planer to 3/4 inch thickness and tapered with a sweep back to get 
20 inches for the wheel axil from the leading edge of the stub wing for the 
stock KR-2.  The amount of sweep will depend on tail dragger or nose dragger 
configuration; they are NOT interchangeable.  I used the full 26 inch 
length.  I used the original Diehl casting to mount to the aft face of the 
main spar.I rounded the leading and trailing edges for stream lining and 
stress riser relief,  I put soda straws in the trailing edges, wrapped with 
fiberglass and foam, for brake line conduits.  Have done lots of taxi 
testing and on a particularly bad speed bump at a taxiway intersection.  The 
gross weight is 1170 pounds.  No problem so far.  No landings yet on these 
gear legs.  Expect to fly soon as the weather cooperates.

--
I recently bought a couple of gear legs that are fiberglass and for a 
Grumman which have indicated that they will support a 2200 to 2400 pound 
aircraft. Obviously a KR as about 2/3's to 1/2's  that. Should I make them 
narrower or thinner (i.e., split them to reduce the thickness by about 50%) 
or narrower (i.e., make the width about 1/3 less than they are now)? They 
measure 3 3/4" X 1" at the bottom and 7 3/4" X 1" at the top and are 26 1/2" 
long.

I think the length is good, but the other dimensions will be too stiff.

What do you guys think? Thanks.

KR> Landing Gear Shims - Where to have made

[Mark Langford]

Somebody asked about having shims made.  One way to do it if it's not 
too bad it to cut them out of aluminum, which only requires a drill bit 
and a cheap tin snip from Harbor Freight.  I made these for N56ML, 
"temporarily", and like a lot of things, they ended up doing 2825 
landings.  So they do work.  Each of these two in the enclosed picture 
is .020" thick, and I estimate that each is good for about .9 degrees of 
toe-in or -out, camber, or the combination when overlapping (as in the 
photo).  The dotted red line denotes useless material (based on wear 
marks) that I shouldn't have been carry around all those years.

You can probably pick up aluminum from some airport scraps, or buy a 
1'x1' piece from AS for cheap...but then there's shipping.  Make sure 
you clamp the piece to the table when drilling...this stuff is thin 
enough to cut you.  I almost lost a fingertip this way when I was in 
college...

KR> Landing Gear Shims - Where to have made

[John Martindale]

Hi Jeff

I did something similar. I just set the toe in and camber using those offset
washers as required between the axle plate and the leg bracket. Then I just
forced epoxy and flox into the gap until it squeezed out the other side. I
smeared the faces lightly with vaseline to prevent bondage. In situ poured
shims you might say :-)

One other thing..both toe in and camber will vary with aircraft weight
due to the offset angle of the gear legs.

And another..  You need to set both with wheels on ball bearing plates
because the friction of the tyres on hanger floor affects the results
depending on whether the aircraft is rolled forward or backward. 

Too whroo

KR> Landing Gear Shims - Where to have made

[Jeff Scott]

You guys are supposed to be airplane builders with skills to build composite 
parts.  Fabricate a small box with the appropriate slant to it for the shims 
you need, then lay up a shim with the dimensions you need. If it's not quite 
right, you can grind, file or cut to suit yourself.  Do a test fit to see if 
it's right, then when you install it, bed it in a thin slurry of milled fibers 
for a no slip perfect fit.  If you have to go a bit oversized on the holes 
through the gear leg to get a proper fit (and keep the bolts straight), grease 
your bolts up with wax (so you can get them back out and backfill the holes 
with a milled fiber slurry.

Additionally, try to drill things so your bolts are straight and use a set of 
self aligning washers on the side where the head of the bolt or nut appears to 
be an an angle to the surface.  Self aligning washers are a pair of washers, 
one with a concave surface and the other with a convex surface. The concave 
surface of one washer sits on the convex surface of the second washer allowing 
them to cock off sideways from the bolt head and adapt to the surface of the 
gear leg.   When you pull a bolt down onto them with a hole that isn't normal 
to the head of the bolt, the two washers will swivel a bit to properly 
distribute the pull of the bolt onto the surface without side loading the axle 
attach bolt.  Just google "self aligning washers".

I used this technique to repair the landing gear on a GlasAir that had the gear 
badly misaligned, then the holes overdrilled and the bolts literally bent in 
the bolt holes hanging onto the axles.

Dave,
Sounds like you have already drilled the holes for the lower ends of the 
gear legs.  If not, clamp in place and drill the holes for the legs and 
brackets; no shims needed.  If so, try Aircraft Spruce 
http://www.aircraftspruce.com/categories/aircraft_parts/ap/menus/lg/axlesandaxlenuts_shims.html
 
Need to get more correction: get two or three kits and double up.  The "how 
to" guide on the AS page may be of some use. 
http://www.aircraftspruce.com/catalog/lgpages/axleShims.php
With the Whitman type spring gear (Diehl) what is the concern with camber?

Reversing the Diehl gear legs is not a practical thing to do.  The shapes of 
the gear legs for the tri-gear versus the tail-dragger are different and not 
interchangeable.  Using the tail-dragger legs for the tri-gear will set your 
main wheels 3-inches further forward from where they need to be.  The axle 
center should be 20 inches aft from the leading edge of the stub wing. 
Otherwise the airplane tends to fall on the tail when you climb aboard or 
dismount.

From: Dave Acklam 
Due to my use of 'conventional Diehl gear-legs, reversed' to make a
tri-gear config, I need 7.5 degrees camber & 7 degrees toe in order to
track straight

The only source of pre-made shims I know of (Grove) sells them for 25/ea,
but only in increments up to 3/4-degree (Toe) and 2 degree (Camber).

Anyone have an idea on where to get larger-angle shims made?

KR> Landing Gear Shims - Where to have made

[Dave Acklam]

I actually had an idea along these lines, as a solution to this problem...

If I were to stack enough washers under the axle-attach bracket to bring
the gear into alignment, coat the attach-bolts & bracket with grease as a
release-agent, and seal the bottom 3 sides with tape

I could then pour a suitable 'structural filler' (Hysol 960F, or (if we're
going to be redneck about it) JBWeld should work) in from the top and
create composite shims with a perfect clamping-surface...

That said, Mark L & everyone else seemed to be using fabricated metal, so I
thought I'd investigate that option first...

KR> Landing Gear Shims - Where to have made

[Dave Acklam]

I bought the legs pre-drilled from another KRlister & at least so far,
other than the 7-degrees-each-side toe-out/8-degrees-camber-out alignment,
they don't seem to be causing trouble with balance on my particular
plane... In it's nose-lightest configuration (eg, fuel tank empty), I can
get in and out without disturbing the plane - although I haven't tried this
with any sort of baggage behind the seats...

They are also expoxied to the aluminum spar-attach mounts, so getting them
off and replacing them (Say, with sawn-in-half Grumman gear legs) would be
rather tough...

This does, however, mean that I am stuck with the hole-pattern I have
now...

If camber-out isn't really a big deal, then that would make shimming
easier

You may also check with aircraft salvage yards for shims. I've seen lots of 
them in years past on factory built airplanes. Mostly on tail drag airplanes. 
I've seen tiny and large and also large plus tiny on same axle to get the 
proper alignment.

Check with a local Ford dealer.  Ford used shims at one time to align 
front ends on ford trucks.  I know they have them but whether they 
are useable for landing gear is something you'll have to determine.

[laser147 at juno.com]

I should have done a little looking before commenting that I thought
Grove made the Sonarai gear that Steve sells.  Steve's website shows the
Sonarai gear sells for $495 and is made of 2024-T351, 5/8ths inch thick. 


The Grove gear (Grove is right here on my airport incidentally) is 3/4"
thick and made from 7075-T6.  Cost is $1205.00.  

The reason I thought Grove made the Sonarai gear is that the Grove gear
looks just like my gear.  I wonder why they want so much money.  As
usual, Great Plains has the best prices for just about everything.

KR> LANDING GEAR LEGS

[Sid Wood]

Concur with Larry Flesner regarding using the Yankee gear legs.
You will need a power bench planer to take the stock thickness down to 3/4 
inch.  The fiberglass is abrasive and will dull the planer blades somewhat. 
A metal cutting band saw will do well for cutting the outline.  Getting a 
consistent leg shape can be difficult to achieve without a pattern and pin 
router.  Of concern for the leg shape is getting the correct cant forward 
for tail dragger legs or cant aft for nose wheel installations.  I used 20 
inches for the main wheel location aft of the leading edge of the stub wing. 
With the dog-leg shape, it is not possible to keep the fiberglass grain 
completely straight the entire length of the leg.  Wrapping with 45 degree 
bias fiberglass cloth will definitely help regarding the twisting action. 
Beware of the fiberglass splinters that the planer and saw will create; sand 
every edge smooth to keep those glass splinters out of your hide.
I have my home-built gear legs installed.  Empty weight is 804 pounds 
including ballast.
Worrying about balance issues now.

If I were to use the "Yankee" gear leg, I'd have someone send me a
tracing of the Diehl leg on heavy stock, cut the Yankee leg to same
profile keeping the "grain orientation" the same as the Deihl leg,
plane down the leg to the same thickness as the Diehl leg, put a foam
lead and trail edge on the leg for shaping and a tunnel for brake
line, and wrap with two layers of KR cloth.  Put the KR cloth on the
leg "on the bias", 45 degree angle.  I would go with a 25" leg on a
KR2 and a 26 1/2" leg on the 2S (tail dragger) and make any
adjustments to the the three point stance with the tail wheel
spring.  Tri-gear will have to stick with the 24" leg unless
modifying the nose gear assembly.

I was led to believe the Diehl gear material is the same material as
the Yankee gear.  Dan did the testing, including drop test I was
told,  and his setup works just fine.  I wouldn't change a thing.  If
you are building to fly and not as a project for your retirement, go
with what we know works and spend your worry time on other parts of
the project.  I'm still smiling from yesterdays 50 mile flight for

That's with a tail wheel, not a nose dragger.  Nose wheel using Diehl

Based on my experience with 30" Diehl gear legs, if I were using the 
Yankee gear legs I would cut them to the same shape and dimensions as 
the Diehl legs, and wrap them with one or two layers of KR cloth to 
add foam on lead and trail edge to shape and run brake lines.  On the 
KR2S I'd cut them to no less than 26" and more likely, 28" for a 
better three point attitude on the ground.  I feel my gear at 30" is 
just right for my slightly longer KR over the 2S.  My KR is 765 
pounds empty and I routinely fly at 1065 to 1100 pounds gross and 
have on occasion flown  as heavy as 1250 to 1300 pounds.  The flex 
seems to be just right without being too springy.  I have video shot 
from the belly back by the tail showing the gear during takeoff and 
landing and they seem to flex no more than maybe 2 or 3 inches at the 
wheel.  They handle just fine on grass strips also.

Your results may vary...

The wrap also allows you to to put some foam streamlining on the leading and

The reason the?Diehl gear legs are wrapped is because the legs have a

The Grumman gear is also a lot wider to start with than the Diehl gear which is

Yep.  Just mark them out with a Sharpie, cut them on a sawbench and round
the edges with a router.  Once you've done that just follow the same steps
as for the 'standard' legs - i.e. wrap them with fibreglass, etc.

The Grumman legs are thicker than the 'standard' legs - by about 1/4" I
think.  I'm still thinking about whether to leave them thicker (to make
them a bit stiffer at the 600kg MTOW I'm aiming for) or plane them down to
the normal thickness.

There is one thing stated incorrectly...the kr2s should actually have a
smaller cg range than the kr2.  This is because the kr2s has a shorter mean
aerodynamic chord.  15% to 35% mac is a smaller range on the kr2s than a

So with the Diehl gear, it's simply assembled and it works out close enough 
to have served people well over the years.  If you aren't using Diehl 
(nvAero) gear legs, you'll have to get the angle from somebody who has them 
and cut yours to match.

Along the same line, the plans call for a CG centered exactly on the 25% 
chord line, 10% each way (15%-35%).  That's an impressively large CG range 
for a plane that is short-coupled and has no flaps, and is a departure from 
the more average range of about 15% from forward to aft CG limit.  For many 
years, conventional wisdom in the KR community is to NOT use the aft 2" of 
the CG range, as the aircraft is likely to be unstable there.(likely gained 
from actual flight experience, rather than choosing nice round numbers). 
This is mentioned in various newsletters as well.   In the 90's Dr. Richard 
Mole did a very methodical stability analysis on the KR2S (which shares the 
same CG range, and should have an even larger range than the plain KR2 due 
to the longer fuselage and larger tail volume).  Below is what I wrote about 
it in my "KR Opinions" piece at  http://www.n56ml.com/kopinion.html :

"An analysis of the KR2S by PhD aeronautical engineer Dr. Richard Mole has 
revealed that using the aft two inches of the published CG range results in 
a fundamentally "unstable" airplane! Don't go there! I've done it 
(accidently) and I can tell you that I'm lucky to survive to tell the story 
(which is also on my webpage somewhere). And if you'll ditch the header tank 
and go with wing tanks (and maybe a SMALL header tank) the CG will not 
migrate nearly as far during a flight, allowing you to set up the plane 
towards the front end of the CG range, where you'll enjoy a nicely 
controllable airplane."

So smart builders will use the range of 8"-14" aft of the leading edge of 
the stub wing, and gravitate toward the front end of it, rather than the aft 
end, or at least start out flying it there...

KR> Landing gear position

[smwood]

Using my weight and balance Excel spread sheet, I can do all manner of "what 
if" math quick and easy.  (Don't know if Mr. Pazmany had Excel, but his math 
is still valid.)  My datum is the leading edge of the stub wings per the 
KR-2 plans.  At my max gross weight I would not be able to load my KR-2 
without tipping on the tail at 17 inches main wheel location.  For flight 
the cg would be 14.6 inches; fly-able but not recommended.  With the main 
wheels at 19 inches that would be the balance or tipping point.  Any loading 
less than the max gross weight would work ok at the 19 inch setting.  The cg 
for flight would 14.7 inches (moving the weight of the main wheels will move 
the empty cg).  To get the cg less than 14 inches at max fuel would require 
limiting the passenger weight to less than 100 pounds.
To get a safe margin regarding tipping, the main wheel location on my KR-2 
needs to be set at 20 inches from datum.  I am fairly certain I have enough 
elevator authority for takeoff rotation.  Time will tell.
Regarding drilling the gear legs for initial installation, just use C-clamps 
to hold everything in position and measure the distance to the axels.  Set 
it where you want it to be.  A carpenter square and your stub wing templates 
are all the measuring tools you will need for that.  Right now I would 
recommend 20 inches.  As Larry says: "Your results may vary."

KR> LANDING GEAR LEGS

[ol' weirdo]

Has anyone made landing gear legs from the fiberglass rear springs that
Pontiac used on vans a while ago?

Bill Weir

KR> LANDING GEAR LEGS - Pontiac Leaf Springs

[Peter Johnson]

Hi Bill.

I took a pair of the springs and tested them for flex.  They would have been 
a bit soft, but quite doable with some additional wrapping.

I wrote of the efforts some years ago, along with concerns for converting 
the springs to gear legs.  You'll have to search the archives.

The Diehl upper brackets are mounted to the spar with the leg angled 
at 45 degrees.  The lower bracket is also 45 degrees.  If you want to 
increase  the camber a bit I'd suggest you modify the lower fitting a 
bit to the angle you want.  I went with 45 / 45 and it has worked out 
well for me.  The Grumman gear legs are made of the same material as 
the Diehl legs but are slightly thicker and wider.  You will have to 
modify them a bit to get similar results, i.e., cut a bit narrower or 
run through a planner to modify the thickness.  Some builders make 
upper gear brackets using 1/8" steel plate. I added about 1/8" of 
fiberglass to my 30 inch legs for a bit more stiffness.  If you use 
the Grumman legs with more than 24" length I'd suggest leaving them a 
bit thicker than the 24" Diehl leg.  With my 24" fuselage stretch I 
needed longer legs to get the correct 3 point stance.

   https://dl.dropboxusercontent.com/u/32133949/IMG_8669.JPG

  I made my lower brackets using a piece of 2"X6"X1/4" 4130 steel 
plate.  I cut through the plate at center going about 3/4 of the way 
through the metal.  I bent the plate at the cut to 45 degrees with 
the cut on the outside.  I had a gusset welled to the inside and had 
the cut welded shut and then sanded the weld to a nice radius.  I 
think the Diehl lower bracket is 2 1/2 inches 
wide.  http://myplace.frontier.com/~flesner/21.jpg

Diehl instructions say to mount the upper brackets next to the 
fuselage.  I moved my brackets outboard 4 to 6 inches on each side 
for a slightly wider gear stance.  That and 30 inch legs instead of 
the Diehl 24 inch legs give me a nice 8 foot wide gear track.

There is much discussion about  "toe-in, toe-out".  I set my track at 
zero / zero and love the ground handling and I get zero tire side 
ware. I also run a slightly lower tire pressure (25 pounds) than some 
and my tires seem to last forever.  On an annual once I found them 
both to have deflated to 15 pounds each.  They still looked 
and  performed perfectly normal although I'd not recommend running 
them below the 25 pound range if possible or unusual side loads might 
cause a problem.  Keep the aircraft aligned with the direction of 
travel when on the ground and that won't be an issue. :-)  500+ hours

Good for him!  Most builders use the "Diehl" gear, which is now available 
from NVaero at 
http://www.nvaero.com/categories/Aircraft-Components/Landing-Gear/.  It can 
also be bought used from builders who've given up the dream, but those finds

I wanted to thank all of you who responded to my call for help. Mike 
Sylvester of Birmingham is sending out a set of gear with locking 
improvements and I think that this should work excellently. I can't tell 
you how much it meant to me that all of you would this kind as to help 
me. Over the last 3 years spent with aviators, it is people like all of 
you who have renewed what was a greatly diminished (read: non-existent) 
faith in other people through many acts of kindness like this.  It's 
going to take me a while to get 1333A up and running, but you can be 
sure that the motivation y'all have provided me was as instrumental in 
this process as anything. THANK YOU AGAIN!!!

KR> Landing gear and brakes.

[Tony King]

Hi Brian,

The only commercially available landing gear for KR2's I'm aware of is Grove
(aluminium one piece) and Diehl (composite).  Cost wise I don't think
there's much difference between the two.  There are KR's with different gear
(e.g. there's one in Australia that has Jabiru landing gear - although
buying that from Jabiru won't save you anything compared with the other
options).  There are also some who have made their own composite gear - a
search of the KRNet archive will turn them up.  Whichever way you slice it,
you're up for a fair chunk of money (and time if you decide to make your
own).  I'm looking at buying some Scotchply and fabricating the mounting
brackets for a replica of the Diehl gear, but that's driven by the added
cost of getting an off the shelf kit shipped to Australia.  If you're in
North America I'd suggest the best option is to go with the Diehl gear (or
Grove if that's your preference).

Cheers,

Tony

I would like to cut the main bar and use it for the diehl length of fiberglass

I would buy the mounting brackets to the back side of the wing and also buy the
brackets to mount the wheel to the spring. Can this be done or is the steel too
heavy verse the fiber glass with all the hardware.

KR> Landing gear idea

[DAN INA GLANDT]

A friend of mine who is 84 or so and flew recon P-38's in WWII was over looking 
at my project the other day and we got to talking about the landing gear.  
(taildragger).  I mentioned that I had thought about replacing the composite 
gear with a taller aluminum gear, but since the wing is built, etc. and 
concerns about forward visibility,   I had dropped the idea for now.  He had 
this idea and I wonder if anyone has tried it or talked about it.   Imagine you 
cut off the bottom part of a Grove al gear say 3 or 4 inches above the bend 
from vertical where the axle bolts on.  Imagine a sleeve that is welded to the 
al part that slips over the composite part and is bolted and floxed on using 
the original holes.  The sleeve is made thick enough at the leading and 
trailing edges to be shaped to a good aerodynamic form.  I can visualize that 
it would be easier to fair in with wheel pants, etc.  
Question :  The composite gear is bolted and floxed to the alum brackets.  I 
suspect it would be a bugger to remove, especially through a landing light 
hole.  Is there a process for removing them?
My friend is in the process of building a plane of his own design that 
basically uses a morphed VP-1 fuselage mated to some morphed KR-2 wings.  
Dan

KR> landing gear

[I FLY KRs]

Hello Joe,

Yes, you could feasibly make them fixed.  The down side is you still do not
have much in the way of ground clearance.  The Diehl gear will give you a
bit more clearance for the prop as well as increasing your angle of attack
for 3 point landings.  It is still not quite high enough for a full stall 3
point but it is better than the stock gear.  Just something to consider.

Steve

  Have finnished installation of the retract mechanism and handle/ acuator. The

very well. the handle twists to unlatch the pins. I may end up shortening 
the outer part of the handle so it isnt as high.

KR> Landing Gear

[bobby burington]

Hello,

I see from the construction photos that it looks like most builders are using 
the fixed tri gear up front and not the retractable .  Wouldn't the retractable 
gear increase the speed of the aircraft ?. 

Since I haven't quite made a choice yet, can you guys give me some feed back on 
the different types of  landing gear ?, pros and cons and why you picked the 
gear type you did ?.

Thanks,  Bobby

KR> Landing Gear

[GREG FISHER]

Bobby,

The retractable gear has had a bad reputation in the KR over the years.  The 
original design had problems folding up on landing.  There have been better 
ones designed recently and if you really have your heart set on retractable you 
should research these.  You will get alot of different opinions on this subject 
and they can get emotional.  My take is this:

It is arguable whether you can really go faster with a retractable set up over 
a conventional tail dragger set up that has been well faired.  In this category 
of airplane I do not think a retractable gear is the best choice because of its 
weight and complexity.  

The Tail dragger might be your best choice if you really want the fastest 
plane, lightest plane, but understand it is more about the pilot than the 
plane's configuration.  You must be willing to learn to be a skilled 
conventional gear pilot. (You may already be) You have to fly the plane from 
hanger to hanger. Landing in unusual conditions--gusty/ cross winds are more 
challenging in a tail dragger.

The tri-gear could be argued to be safer as they are a bit more forgiving.  I 
know I will get argument on that statement, but it really takes talent, 
dedication and practice to consestently make 'good' landings on conventional 
gear.  However, that wheel hanging out front is going to cost you some weight 
and some speed.

I know this is one of the fundemental decisions about your building options.  
It is petty cool that you can build it anyway you want though, isn't it?

[Myron (Dan) Freeman]

Hi Bobby;

This is an excerpt from "New Builders Checklist of Commonly used KR 
specifications."
http://www.kr2forum.com/phpBB2/viewtopic.php?t=104

Stay away from the retractable landing gear unless you just must have it, 
remember KISS. Fixed tail draggers with good "wheel pants" are slightly 
faster anyway "Diehl or Grove" brand and fixed tri-gears are easier for some
pilots to handle on the ground but are slightly slower in the air. Your 
choice.

-On the subject of landing gear, wheels and brakes. You might do well to 
use this shopping list suggested by Stephen Henderson unless you know what 
you want and have a preference already.

>From Dan Diehl at Diehl Aero-Nautical,  http://www.diehlaero.com/landing.htm

(1 set of 2) C-90 Hydraulic Disc Brakes for Cessna-Style Gear --- clean

removed without removing brakes. Same style as used on F-16's I'm told.
(2) 5"x 3"x 5/8" Tri-Star wheels --- low cost and seem to be widely used.
(2) Sawtooth tread tire with tube 410-350x5" --- one stop shopping, decent

KR> Landing Gear

[D Lively]

Bobby:

Many have reported that the fixed conv. gear configurations are slightly 
faster than the retract version.  They speculate that it is because the 
wheel do not fully retract therefore making the airflow more disrupted than 
the fixed cov. geared version.

This has bee n talked about at length.

I'm not Lee, but one option is shown at 
http://home.hiwaay.net/~langford/kgear.html .  I'm going to bolt these 
extended lower brackets on one of these days soon.

On another note, I was at a manufacturing facility in Minnesota the other 
day that makes the gear legs for the Cirrus. The gear legs looked just like 
KR legs on steroids, about 7/8" thick or so.  I commented that it looked 
like 3M Scotchply, and the guy said "right, they WERE 3M, but now Raytheon 
makes it".  Just in case anybody starts looking for gear leg material...

Hey Thanks very much Mark that sounds like that could also help in some 
weight savings.
I live in Wichita and Raytheon is on the other side of townso I might be 
able to get them in short order Thx again

Make that "Morton Thiokol".  Apparently Thiokol bought that line of 3M's
"aerospace" products.

KR> landing gear

[mar...@simerson.net]

Hi all
Ok a slight change in plans, I was planing on going with a tricycle
landing gear but after talking with people I have came to the conclusion
of going with conventional gear "lots of grass around hear".

I already have my main gear" deal" I read in the instruction that the L.E.
of the trygear has a crook and the conventional is straight

what are your touts can I use my crooked legs or do i need to order
straight ones.

I think he meant main gear "Diehl" and if that is the case, Keith should
call Diehl and ask him this question. Who knows Keith, Dan Diehl may
even swap out the gear if it is new in the box. Here is Dan Diehl's

I may be wrong but I believe the main gear leg is the same for
trike or conventional (Diehl gear).  The leg is cut at an angle
at the top where it mounts to the upper casting.  For the
conventional gear this angles the leg forward and for the
tricycle gear it angles the leg to the rear.  The gear is mounted
on the forward side of the spar for conventional and on the
back side of the spare for tricycle.  If your gear is not already
mounted you should be able to go with what you have.  If
mounted, the holes will probably not line up when switching
from rear to front so some minor spare repair (filling the holes)
and re-drilling may be in order.  Not much of a hill for a climber. :-)
Check out the Diehl site for instructions and I think the info is
all there.

Thanks for the information.  Next question is does anybody have some landing 
gear plans they could send me (offline to dfde...@earthlink.net).  I am 
thinking about using an A65 continental (any commnents/thoughts?) and would 
need as much room for the prop as I could get.  I also thought about buying 
the Pazmany book on landing gear.  Can anybody tell me if this book would 
give me enough info to size the tubing and construct the gear ( mains and 
nose).
Thanks,
David Denny

The Pazmany book is a good one, but spends a lot of time covering gear on 
stuff like airliners as well as small planes.  I don't think it goes into 
specific details of materials and sizes for small planes, but it does show 
where your gear needs to be with respect to CG and that sort of thing.  He 
has another book called "Light Airplane Construction" that has all kinds of 
stuff in it, and two pages with some neat diagrams that you'd find handy. 
One of them is at http://home.hiwaay.net/~langford/gear.jpg , and tells a 
lot of the story.  I think the best way for you to "design" one is to see 
what other folks have sucessfully used on planes with similar weight as 
yours, and shamelessly copy theirs.  There are several web sites where folks 
have made their own composite landing gear, which has the advantage of 
allowing you to make it any length you wish (i.e. longer than the 24" Diehl 
gear)...

I seem to recall that one of the Tony Bingelis books covers landing
gear and would be a good source.

Greetings to all,
I have enjoyed listening to you guys hammer out KR issues.
I was wondering where would be best place to purchase landing gear for the 
tricycle configuration.  
Thanks,

More than a few have built their own.  If you are looking for
gear that will just bolt on you probably can't do any better
then the Dan Diehl gear.
