KR> VW temps

[Roger Bulla]

Ron

Mine seamed to run a little cooler after 5 to 10 hours. After 20 hours I 
changed the  oil from straight 30W to 10w 40 synthetic and that brought the 
temps down even more. I'm running 10w 40 synthetic bend now. But I agree 
with Jeff that if your using 100LL all the time it would be better to run 
conventional oil. I run premium non-ethanol unleaded all the time except 
when flying cross country.  That?s why the blend.

KR> Cylinder Heads Again

[Roger Bulla]

Mark Langford wrote:

>I'm still looking for ideas on "what works" in various VW aircraft
installations, because what I have isn't working.  I took off in 95
degree temp yesterday, and after idling to the runway and a quick runup,
it was at 400F as I turned crosswind, and I wasn't even at pattern
altitude yet!<

I spent some time looking through my engine log book for my first KR and the 
CHTs were always in the 400 to 425 degree range on climb out and then around 
375-400 in cruise. The last set of heads on that engine were CBP 044s. I 
purchased then 1990, and had 150 hours on them when I crashed in 2009. When 
I tore them down the exhaust valves had a lot of wear in the seating area 
and all the valve spring retainer groves were really worn, along with the 
valve guides. I had done many different things to get them to run cooler 
including installing adjustable cowl flaps. I gained the most by smoothing 
out the cowling exits and changing to full synthetic oil. I remember reading 
some people reporting a  higher CHT using synthetic, but I did get a 
consistent 25 degree drop in CHT. Of course, the oil temp went up from 170 
to 190 in cruise. Not enough to worry me.

I have rebuilt the old 044 heads with new valve guides and new 214NSS 
stainless valves from CBP and recut the valve seats with a Neway cutter. I 
currently have about 75 hours on them. I Flew on a 100F degree day over the 
weekend and here are the temps I got.

Climb:  330F, taken under a cylinder head stud and 410F under a spark plug. 
(I think I got hotter than that).
Cruise at 6500 ft. 3200 RPM, 145 MPHI:  300F under the stud, and 350F under 
the spark plug.

The engine is a 2180 with the compression ratio set at 7.2:1

I always pull the prop through four blades to make sure the valves have not 
developed a leak. I have 75 hours on the heads and the engine is still 
running strong and smooth, but now after shut down and pulling the prop 
through I have a slight hiss coming from one cylinder out the exhaust pipe. 
If I let the engine cool for 10 minutes or more the leak goes away. Maybe a 
sticky valve guide?

It will be interesting to see how your DPD heads hold up.

KR> RUDDER SIZE

[Roger Bulla]

My kr2 is a plans built kr. I think it needs more rudder area. it seems like 
I need more airspeed before the rudder becomes effective as compared to my 
old kr. I never measured the rudder on the old plane, but I think it was a 
little larger than plans. I run out of rudder in hard slips before running 
out of aileron. Could be there is not as much deflection before hitting the 
stops. I'll do some measuring on my KR.

Flying is not cheap.   Neither is boating, fishing, golf and just about any 
hobby you try. No matter what engine you pick it will cost between $5 and $8 
thousands after all expenses. I believe flying a KR is about one of the 
least expensive planes you can fly and travel in. I can tell you from my 
standpoint. I am on my 3 wife (the 3rd one likes flying) and in the last 25 
years I have had the opportunity to build 1 KR and own 2 other KRs and have 
had fun with all of them. I have gotten larger  I have moved into bigger 
faster airplanes. Not a whole lot faster. My KR with an O200 cruised at 
about 140 knots  the one I have now will also cruise at about 145 knots but 
it is heavy with a big engine EJ22. I had to move into a Cessna 310 to get 
the room I needed and speed I wanted.

Carbon Fiber Sale 6oz Plain Weave and 6oz Uni



6oz Plain Weave Carbon
We got a great buy on some really nice fabrics and we're passing on the savings 
to you.  

The first is 6oz plain weave carbon fiber fabric.  This is a 200 gsm 13 x 13 
count 3K carbon fabric.  What that means in english is that it has a slightly 
higher yarn count per inch (13 instead of 12) which results in better hide in 
applications with just one or two layers.  This is a first quality material 
woven to aerospace specs. This material is 50" wide. Prices are as follows: 

100 yard roll, $16.44 per yard
Cut 16 yards and up $17.49 per yard
Cut 4-15 yards $19.43 per yard
Cut 1-3 yards $25.88 per yard
It can be found here on our website
Here you go. I just made my cowl pieces using two plies of CF with more around 
the perimeter and some stiffeners (from 1/4 X 1" wide foam strips glassed in. 
Light and stif. A hair dryer or heat gun on the CF helps it to lay in the mold  
and with malicious squeegeeing, reduces resin. The first layer was 1.25 oz. 
deck cloth.  Molds are wonderful after they are made.

KR> Adverse Yaw

[Roger Bulla]

I saw a notable difference in performance on my first KR installing gap 
seals, but it was built using three piano hinges only about 10 inches long 
spaced out evenly along the length of the aileron so there was a open gap 
from bottom to top.

On my present KR I installed gap seals before I took it to the airport for 
the first flight, so I am not sure if there was any gain. It climbs, turns 
and flies great. Maybe I'll pull them off sometime and check the performance 
without them. Or maybe not.

Hi All,

I was just reading an old article by Stu Robinson in the March 1994 KR 
newsletter.

In it, Stu points out that the aileron gap serves to increase drag on the 
down wing, thereby reducing or eliminating adverse yaw.

However, I also read an article about how important gap seals are for 
increasing climb performance.

So?
Gaps seal?

(I?m working on a RAF KR2s thats pretty close to plans.)

KR> Question for Roger Bulla

[Roger]

Chris

The Tillotson does not have a idle cutoff per say, but all fuel going to 
both the idle and main circuit has to go through the main needle. If you 
turn the main mixture to the stop the engine will quit even at idle.

I always shut down using the ignition switch and leave the mixture at the 
setting it was when I landed, just a tad rich. It has never dribbled fuel 
while sitting even when I forget to turn off the fuel valve.

KR> Roger's carb

[Roger Bulla]

Roger: what don't you like about the speedometer cable adjustment of the 
mixture?  Is it not fine enough?  You could add a small lever arm to the 
mixture screw and make the mixture adjust by push-pull with a standard 
vernier type mixture knob.  Depending on how long you made the lever you 
could push the mixture knob in/out by a full 3" of stroke and only move the 
mixture screw by 1/4 turn if you needed finer adjustment.
Also, I see from the HD carb (as on the 1960s Harley Sportsters) exploded 
view that the idle adjustment screw is on top of the carb.  How do you get 
to it with your setup?  Looks tight ;o)

-Oscar


Oscar

With the speedometer cable I get very fine mixture control, the part I don't 
like is the cable tends to wind up and you don,t have a positive feel when 
making adjustments and the fact that you do not have a visual of where the 
mixture is at a glance.  From sea-level to 14000 feet I need about one full 
turn to keep things where I like them. But it still gives me precise control 
of the mixture. I have been looking at miniature gear boxes the have a 3 to 
1 ratio that I could use a push-pull control on.   Maybe I'm over thinking 
it.

On this particular HD the idle mixture screw is on the  lower left side of 
the carb as you are sitting in the plane. The main mixture screw is on the 
right. It seems as with many carburetors, there were a lot of variances 
depending on the application.

KR> Roger's carb

[Roger Bulla]

Great pictures from the Gathering, Mark!  That carb on Roger's plane has had 
me zooming in to look at it from all angles for half an hour.  No idea, but 
it's a side draft with mixture control and a choke.  Looks like he has the 
mixture control set up like the Zenith, with a twisting of the cockpit knob 
to screw the needle in and out and a tension spring on the needle screw. 
Oscar Zuniga
Medford, OR

Oscar

The carb is an old Tillotson off of an old Harley I believe. Someone gave it 
to me many years ago, so thought I would give a try.

This is a Tillotson HD that uses a pressure control diaphragm. The HDs have 
a 37 mm venturi. The tube on the bottom is a balance tube to let the 
diaphragm see the same pressure as the intake sees. The pressure deferential 
created by the venturi will regulate the fuel available to the engine. I got 
the idea of the balance tube from pictures of Ellison carbs. They have the 
same diaphragm and balance tube built in. Without the tube, the diaphragm 
will close when the throttle is pulled back at higher airspeeds because of 
the ram air increasing the pressure on the fuel side of the diaphragm, 
causing the engine to quit until the throttle is opened back up.  This 
always raises my stress to dangerous levels. (The port into the intake must 
be facing the incoming airstream.) The tube is only for balance between 
venturi pressure and ram air, not altitude compensation.

Other that the use of a speedometer for the mixture control, this has been a 
very good carburetor. It runs smooth at all power settings and I can adjust 
the mixture in flight right where I want to run, and with the choke it 
starts and idles very well. The fuel distribution seems spot on. All 
cylinders burn the same. I have a 1.5 psi fuel pump to feed the carb, with a 
return line for excess fuel, but also have it plumbed to gravity feed as a 
backup. It seems to run fine on gravity feed. On the Harley you have only 
about six to eight inches of head pressure. I have seen these on Ebay, but 
have noticed the prices being asked are going up.

I'm going to continue using the Tillotson, but I am trying to come up with a 
better mixture control, than a speedometer cable.

KR> Gathering

[Roger Bulla]

Thanks to Dan John and Pete for all the work for the gathering. Learned a 
many new things and had great time. Kim and I arrived back in Grand Junction 
around 5:30 mountain time yesterday, with just a little interesting 
turbulence in northern Utah and Colorado. Again thanks to all at the 
Gathering.

KR> KR engine mount?

[Roger Bulla]

I'm slow at responding, but I have a engine mount the looks like the one 
Mark is using hanging in my storage shed. If it could be used I give to 
Keith for the shipping. It came off my old KR2.

I think I used up a big portion of good luck in that crash. Can't thank 
Larry and Chris Collins and every one else enough for all the help.

I thought I would throw my opinion out there on "gathering" locations. I've 
only been to two. MTV in 2012 and Chino last year. Of course that is not 
counting 2009 when I crashed.
I flew my new Kr to Chino last year and it was a great fly in. I'm still 
partial to MTV. When I made that big mess in the bean field, Larry and the 
airport manager Chris Collins and some others cleaned it up while I was in 
the hospital. Chris helped me in so many ways and helped me load what was 
left of my kr in my truck the next year.

Mount Vernon airport seems as close to perfect as one could hope for. Great 
camping area, large hangers and a terminal building with a restaurant and 
conference rooms,  long wide runways and relatively low air traffic. It is 
also nice to be close to the runway for flybys and watching airplanes. While 
it is not right in the middle of the country, it's close. Chris Collins 
works overtime to accommodate the gathering and keeps the atmosphere 
laidback. I stop by the airport once a year when out visiting relatives and 
Chris always takes time to show me what is going on around the airport. 
Plus, it is very easy airspace to navigate. Of course Larry does a fantastic 
job of organizing the event.

Chino was a good refresher on airspace regs and navigation.

Flying long cross counties in these small planes is a challenge. You have to 
really want to do it and plan carefully. I agree this Mark that we should 
have the gathering in other places around the Country, but keep utilizing 
Mount Vernon as kind of a "Home Base"

Looking forward to this years gathering if I can make my schedule work out.

Roger Bulla

Yes, I did forget something.  There was an AirEvac helicopter, in the
air, waiting for Roger Bulla to plant his KR in a nearby bean field,
then picked him up and flew him to the hospital.  I can't take credit
for planning that support as it was not a scheduled event but it did
happen.  :-)

I'm no aerodynamicist but seems to me the proper way to fix this problem

Mike,
If one were able to move the wings forward, one would actually be making 
it more tail heavy. Try it with (what used to be a) nickel glider that 
has the wing in a slot.

KR> OT: heat rejection capacity from exhaust port walls

[Roger Bulla]

I had a company in Denver do their version of ceramic coating on the inside 
and out side of my exhaust pipes. I have about 100 hours on them now and 
they have not discolored at all and do seem to help keep the temp down in 
the cowl. The coating seems very durable. I scrape the pipes pretty hard 
getting the cowl on and off without scraping the coating off.  I'll have to 
go through my records to come up with the name of the company.

Great time and thanks again to Steve for putting all together.

I have talked to Bob Said who couldn't make it due to a prop strike. He has 
rented a u-haul to get his plane in St. George Ut. and bring it home. He 
wants to check the crank be for he flies it again. Always a good idea.

Glad to see you getting close to your KR back in the air.

I had the same problem on my Zenith on my old KR. I solved it by drilling 
out the main fixed jet in the bottom of the float bowl. I just used some 
Acetylene torch cleaners to ream the jet out ever so slightly.
That made the mixture stay more constant throughout the full throttle range, 
and it enriched the top end to acceptable levels.  Of course I didn't have a 
Mixture Meter to see instantaneous readings only an EGT, but it seemed to 
work. There is a lot of black magic going on in an intake system.

While I am, here how the hell do anyone tune a revflow carby I can tune the 
mix at the needle to run smooth at full throttle soon as i pull it back 
under about 80% and to idle, the engine sounds so rich it wants to drown! 
and have to continuously fumble between throttle and mix while flying.Some 
suggestions would be handy.

Robert

I don't have an answer to the question of the Revflow. I have been trying to 
get the one I have tuned to where it runs smoothly at all throttle settings, 
but still no luck. I have Joe at Revmaster sending another needle to try. If 
I get the top end OK it will stumble in the mid ranger, generally right at 
the RPM I would like to use in pattern. If I get it run well at midrange the 
top end is way to lean or rich. I bought another needle from Revmaster a few 
weeks ago that brought the top end mixture where it needed to be, but was so 
rich at part throttle that I had to bring the mixture almost to idle cutoff 
in pattern to keep the engine running. Also when tuning with the plane on 
the ground with the tail tied down and the cowl off, I get it to run pretty 
well playing with the needle adjustment, then run terrible with the cowl on 
and in flight.

I did try a tilotson carb last week. It is a little large but worked good at 
high throttle settings but again would stumble in midrange, and sometimes at 
idle it will die with out warning. It will always restart with the choke on. 
I had rigged up a speedometer cable to control the main mixture needle. I 
wonder if the midrange stumble on both of these carbs is due to the large 
passages in the intake manifold? It has been cold and it seems to me that 
the fuel is falling out of the air stream at lower throttle settings and the 
cold manifolds. I remember reading something about this in a book on 
carburetor tuning I had read many years ago.

On my old KR I was using the Zenith that Great Plains sells with a single 
runner manifold to the heads. That engine was also a 2180 cc. That 
combination work very well for many years. It ran smooth throughout the 
throttle range, summer or winter, idled well and was easy to start. The only 
thing I did not like about it was using a speedometer cable to control the 
mixture. I like the robustness of the hardware on the Revflow. I am going to 
try one more time with the new needle, but I am getting all the parts 
together to use the Zenith again.  I want to fly the plane and not fixate so 
much on the carburetor. Right now I am afraid to go far from the airport. Of 
coarse I will have to do some glass work on the cowling to make the Zenith 
fit and come up with a mixture control for it, because it needs to hang 
lower under the engine.

KR> belly board flying characteristics?

[Roger Bulla]

I had installed a belly board on my old Kr. It was just in front of the rear 
spar and actuated with a linear actuator. I believe the board was 30 inches 
by 6 inches. I noticed little to no change in pitch when deployed, but did 
add bunch of drag. Something I should have done to that plane years ago. My 
present KR has stock flaps and there is a big change in nose down pitch when 
deployed.

I'm about to hang a belly board on N891JF, so I'm doing a little research. 
I plan on putting the hinge point underneath the main spar, and would expect 
deploying the flap would nose the plane down, requiring nose up trim to 
compensate.  That's how the flaps on N56ML work, at least.  Does anybody 
experience different results from a belly board, and if so, where's the 
hinge point for your belly board?

KR> N6338Z update

[Roger Bulla]

It has been a while since I posted a update on the KR. It is now flying! This 
is a plans built KR-2 with a VW 2180. Took its first flight in late October 
2013. No surprises. I have the original Rand fixed gear that looks very close 
to the Grove gear. Visibility over the nose on the ground in nonexistent, but 
ground handling is good as well as handling in flight. I biased the cg toward 
the front to keep it stable and plus it is easy to correct  a nose heavy 
aircraft. My cg is around 1.5 inches in front of the center of lift with me in 
the plane and low fuel. Of course the pilot has shed around 30 lbs since then, 
so it has move a little further forward.

The aircraft seems straight, with the elevator trimmed, if I let go of the 
controls I get a very gentile turn to the right. When the power is pulled back 
and the stock flaps are extended to descend, the nose gets very heavy, but the 
plane is stable and easy to land.  The only real problem I have is getting the 
Revflow carburetor to work properly. It keeps trying to kill me or at least 
keep my heart rate up. I have talked to Joe Horvath he is going grind a needle 
with a different taper on it to see can get to settle in. I have a Tillotson  
HD that I am about ready to try. I also still have the Zenith I used on my old 
KR that worked very well for the twenty years I flew it.

I hope to get some wheel pants and a coarser prop on the plane soon and get it 
ready to make the gathering this year. I currently have an old Sterba Prop, 
(54x46) that I have had as a spare for many years. It came with an engine I 
purchased in 1987 and does a great job flying around the valley here in Grand 
Junction, but the engine needs more pitch on the prop. With the Rand fixed gear 
I have plenty of ground clearance for a longer prop. With the 54 inch prop, and 
in a level attitude I have 14 inches of ground clearance but I am not sure what 
combination of pitch and length will work best. 

Its Great to be back in the air. These little planes will keep you grinning.

KR> getting close

[Roger Bulla]

Update,

My kr still will not be at the gathering. I have just had a local paint shop 
spray the paint on and have it back home. I just have some minor details to do 
before it goes to the airport.
I am now in the FAA morass to get the limited airworthiness certificate 
updated. The Salt Lake office decided that since the certificate was issued in 
1999 and only 30 minutes were on the plane, that I need to have the local DAR 
inspect it again and will most certainly have to fly off the 40 hours of 
restriction. Of coarse I have rebuilt most of the plane so it won't hurt. Just 
another delay. The joys of buying a project the has already been in the system.

I hope to make it to the gathering by commercial flight this year, but depends 
on some family matters.

KR> KR2 Canopy

[Roger Bulla]

To the point: How high is the seat bottom from the fuselage floor?  You
might be able to get some room by lowering the seat.

Sid is on to something. A friend has a KR2 with a dragon fly canopy, but 
your head is crammed toward the center. The problem is the seat is to high. 
It is great seat, just to tall.
On the my KR I have the plans built sling seat and canopy. I lowered the 
sling seat by changing the attach point to where they just clear the torque 
tube for the flaps. It will give me enough head room to be able to 
comfortably fly the plane.

G?day All ? As a first time user of this page and a new owner of a KR2
(purchased eight months ago) and having flown some five hours in my
retractable taildrager I am searching for information on the KR2 canopy.
I have found it comfortable but not visually stimulating sitting in the
cockpit of a KR2 and would hope that someone has a suggestion to at least
raise the canopy to increase the seating height. In my opinion raising the
canopy some hundred millimeters (four inches) would be around the mark. I am
open to all suggestions or direction.

Found the webb page interesting.

KR> Re: Stock Retracts

[Roger Bulla]

Glenn
I had the stock retracts on my kr for the 22 years I flew it. They can be 
made to work pretty much in stock form. Mine had spring loaded hold-down 
latches, the left side with a positive latch, and never collapsed on some 
very bad landings and on some very rough fields. When dropped in real hard 
the spring bar would pop a hole in the top of the wing roots, but would take 
the punishment. I was going to replace the 3/4 inch spring bar with a 1 inch 
to get rid of some of the sag mine had before I crashed the plane. Having 
said that, I would agree with Larry that spending your resources on fixed 
gear would be a better way to go. My new kr project has Rand fixed gear. If 
you still want to pursue the retracts I have the stock gear legs, wheels, 
mechanical brakes and tires that you are welcome to. Email me if want them.

As I continue to research the stock retracts on the KR. I keep hearing about 
how hard landings can
overload and possibly bend the landing gear.

KR> POT OHM OR K?

[Roger]

Joe, a lot depends on the circuit that it's in, but for experimental 
purposes with your result sofar, try a 5kOhm linear taper and if that 
still doesn't do enough, try a 2kOhm. You may need to use a wirewound 
pot rather that plastic depending on how much current you are dissipating.

KR> Bolt Corrosion

[Roger]

Sid,
Try an anti-corrosive. CorrosionX makes a series of products that 
address this problem. I use CorrosionX-Aviation for electronics (it's 
"milspec") and CorrosionX-HD for hardware. http://corrosionx.com/
I have no affiliation with this company, I'm just a fan of their 
products. I have been using these two types for over 4  years on my '93 
BMW 850 which is electronically VERY complex and notorious for 
intermittants. I have no such problems any more. Their spray bottles are 
the best deal and last the longest. I usually just dribble a little on a 
Q-tip or my finger or epoxy brush and wipe onto the part(s).
Cheers,

Paul,

I flew my KR for 20 years with some cheep automotive battery cable that was 
thick strand wire. Same problems, hard starting especially in the winter. I 
had an older non-geared starter. The battery was under the cowl on the left 
side. When I rewired the plane I replaced the battery cables with some 
aircraft rated cable I inherited from an abandon project. The wire was  very 
fine stranded and probably 2 or 4 gauge. It made a big difference! I no 
longer had to hand prop in the winter. Just jump in, pull on some choke and 
start.  I would believe that with the with some good cables, the battery 
location would not make a lot of difference. Besides, how far away can you 
put a battery on a KR?

KR> Second Crash at MVN

[Roger Bulla]

  HI to all and "Thank You" to those at the gathering who signed the card I 
received while in the hospital! It lifted my spirits considerably, and thanks 
to Larry Flesner for sponsoring the gathering and his offer for help remove the 
wreckage from the bean field.

I am glad to hear that Dan Freeman is doing well and I see he is posting 
again. My injuries were minor despite the total loss for my KR. I think all 
that wood and foam snapped, crunched and cushioned my impact. I RAN OUT OF GAS 
A MILE SHORT OF THE AIRPORT!  What an idiot. Anyway, I hit a row of trees at 
the end of the field I was attempting to land in and that caused the plane to 
nose over and go straight-in on the other side of the trees. Just bumps and 
bruises and five broken ribs. What luck that the AIR LIFE helicopter had just 
lifted off and watched me go in, land and rush me to the hospital in ST. Louis.

This my first post but have been reading posts for over a year. A lot of 
good info. Before my crash, I have owned my KR for 22 years. This plane was 
finished in 1984 and was plans-built, with stock retracts. I bought it in 1987 
from a friend who built it, minus firewall forward. I built and install a 2180 
VW. I put over 800 hours on the plane and had very few problems with the plane 
or the landing gear. The retracts will work if you keep an eye on the fittings 
and latches, although I was planning on converting to the Diehl fixed gear in 
the near future. I am now looking around for another KR finished or a project. 
The Kr is a great aircraft and just a lot of fun to fly and work with. I never 
kept track, but I probably had 200 - 300 hours maintaining and improving my KR 
over the years.
For those of you building or considering a KR, GO!! It is well worth it.

KR> RE: Dropped valve seat.

[Roger H. Reese]

As an old Corvair mechanic and driver, let me assure you that floating valve
seats is not a rare thing with those engines, although it is more often the
exhaust that falls out. This is one of several design faults that made me
discard the notion of using one as an aircraft engine. Just my $.02.

KR> Toe in

[Roger H. Reese]

I used to be an auto mechanic. I did a lot of front end work, and I know
that the proper toe on the tires depends on the camber angle. A tire tends
to roll in the direction it is leaning, if it is tilted out at the top
(positive camber), it will require enough toe-in to counteract this
tendency. The best way to be really sure is to use a scuff gauge, roll the
wheels across it with the plane in normal landing attitude,  and adjust toe
for zero scuff. An old Air National Guard mechanic told me that they checked
scuff by greasing the bottom of a small piece of sheet metal, laying it on a
concrete floor and tracing its position with a pencil, rolling the bird
across it and noting if it moved. Ghetto type scuff gauge, but it worked!

KR> hole in LE

[roger mitchell]

larry, this is roger mitchell, I work at TWA-AA overhaul in KC Mo, when we do 
composit repairs we use a perferated plastic on the cloth/resin layup then a 
solid plastic film, tape down firmly both layers, second larger than the first, 
and use a plastic applicator to push out any air bubbles, on the airliners we 
use vacumn( 21" hg) for air removal and pressure & heat for curing, probably 
wouldn't work on a KR. THE NEW " SARAN WRAP " with the cutter works 
wonderfully. layup is commonly done with the first piece the size/shape of the 
hole then up to four layers( depending on original thickness) each 1/2 larger 
than the first on all sides layed on in reverse order. the easy way to 
accomplish this is to first work epoxy into the cloth between two pieces of 
heavy plastic film,draw the shapes needed,cut out, and peel-n-stick. if you 
want you may call me at 816-305-9689

KR>kr2 sportpilot?

[roger mitchell]

just a thought, sailplanes use high aspect ratio,tapered wings,commercial 
aircraft do the same,a hersey bar is easy to build,but may be ineffficent  in 
compairison and use a larger heaver spar just a thought

  "Extended wing, slotted airfoil, Hershey bar wings, longer gear legs..."


  I'd be interested in discusion of Hershey bar wings.  Is the extra area
  worth the effort?  Wouldn't that effectively move the center of pressure
  aft?   Has anyone tried washout?  How much? Effects on performance?

  Ladies and Gentlemen of the KRNET:

  It is my proud honor to announce that after 3 1/2 years of dedicated 
  construction, my KR-2S with Subaru EJ-22 has taken flight.  On two occasions 
today, 
  N4027Y leapt off of runway 25 at Lompoc, California and climbed like 
  an...overpowered KR-2S.  It flies straight and level with the elevator trim 
in the 
  neutral position and has no adverse roll tendency.  At low altitude and an 
engine 
  rpm of 4,000, (max will be about 5,000), 
  I was indicating 160 mph.  I'll keep you all abreast of max climb and max 
  cruise speeds as I cautiously approach the outer limits of the performance 
  envelope.

thinking of using for the stick.
  Has anybody any ideas as whether this is going to be too large Diameter to be 
practical?? by this I  mean is it going to be too bulky and get in the way all 
the time?   I know it's over kill but hey it's free!!

  Remember the home builders motto if it costs money it's too expensive.

KR>Rudder Cables.

[roger mitchell]

off the subject, or back to the question, when fiberglassing if you use a hair 
dryer on high heat/low wind it can help the resin wick into the cloth. it's a 
good way to keep from using more resin than is needed, paint the surface , lay 
on the cloth brush or squeggy while applying heat and pull the resin through 
the cloth, we've used this methoid at TWA/AA for many years even outside in the 
winter in kansas city

  Hi guys

  I am also a bit concerned about the rudder control system but I guess we
  shouldn't get too worked up about it because I haven't heard of any KR
  accidents from bent rudder horns. However I did find this interesting
  post on the matronics pietenpol list:

  "If you use pedals, they MUST be connected to a front rudder bar with
  rods, to keep from tearing the rudder horn loose...in flight this could
  ruin your whole day.  Personally, I have no problem with the rudder
  bar."

  I also found several accident rerports that talk about bent, broken and
  jammed rudder horns from application of excessive pedal forces.

  The bellcrank idea sounds excellent, and it could be placed behind the
  seat, in front of the pedals (maybe in front of the firewall) or you
  could even incorporate one into the rudder pedals (ie a rudder bar).

  I've had my Tripacer insurance for 5 1/2 years through Scott "Sky"
  Smith and I'm now with the third insurance company.  They are
  great people to work with but I recently tried to get insurance
  on the KR (liability only) and they coundn't find anyone that 
  would insure it.  

  Avemco said they would give me liability for about $1000 a
  year.  I plan to get 3 months coverage just before my 
  first flight (soon) and then get a re-quote.

  I was "playing" on the runway today and bystanders said
  the tail was up on one run for 50 feet or more.  I couldn't
  even tell it came up as it was tracking straight as an
  arrow and required little if any rudder input.  Something
  to be said for my 8 foot wide gear and the 24 inch
  stretch on the fuselage.

  Subject: KR>fairings


  Netters;

  Someone asked the question about the possibility or benefit of fairing the 
  tailwheel.  I haven't seen any takers on that, so I thought I'd throw out 
  something I just read in the Fall '03 issue of "To Fly" last night, about a 
  Thorp T-18 that a gent built and documented the performance changes due to 
  fairings, cowlings,  and etc. since the Thorp was originally conceived and 
  designed as an open-cockpit airplane with the engine cylinders hanging out 
  in the breeze and unfaired Wittman-style spring gear.

  The Thorp is similar to the KR in a few ways, but that's not the point.  
  What is of interest is the magnitude of the gain for each modification or 
  improvement.  Among other things, the builder said that each of the 
  following gained 2 to 4 MPH in top speed: adding wheel pants, fairing the 
  pant/landing gear leg junction, and fairing the tailwheel spring.  He did 
  not mention a "pant" for the tailwheel itself.  He also said that 
  down-pointing exhaust stacks cost him 3 MPH (ergo, Mark Langford's approach 
  of turning them into the slipstream.  Also a potential for some thrust 
  gain).  He figured that with the fairings and streamlining he did on his 
  airplane, every 10 MPH gain in top speed due to drag reduction equated to 25 
  fewer HP required (for the Thorp)... with the associated weight, complexity, 
  cost, fuel consumption, and the rest of it.  And of course the rate of climb 
  has the same gains and losses as top speed.

  In passing, and since it's Friday (in Texas, anyway), here's something I 
  didn't know... also from "To Fly".  Art Chester, the racer who built the 
  "Goon", "Jeep", and "Swee' Pea" back in the pre-WWII days, worked for North 
  American and was on the P-51 design team.  He is responsible for the design 
  and construction of the innovative box-beam bed mount for the Allison engine 
  in the P-51.  Also interestingly, the British specs for the airplane (we 
  made some for them) were for a pilot size of 5'-10" and 145 lbs., which were 
  Art's exact measurements.  So he was the "test dummy" for fitting the 
  cockpit of the prototype to the British specs and everything was made to fit 
  him.

  The longer I live, the more I learn!
