KR> Composite KR

[ttcse/Tom]

Hi Charles, 
 
Morphing a Dragonfly toward a KR2 is also what I have in mind.I haven't 
decided on a header tank but I would have hollow wings with fuel-tanks in the 
inboard leading edge.   The LongEz and Cozy have fuel-tanks in the strakes and 
use a different foam in that area which doesn't behave badly when exposed to 
leaking aviation fuels.  In addition to Dragonfly plans, I have plans for both 
these canard aircraft too and followed their mail-lists for years but decided 
they're not for me.   I also have the foams and fiberglass for a Cozy which I 
would utilize.   
 
I suspect there are others out there with the same inclination. 
 
Tom

Watching this discussion of fuel tanks closely.  I have built a Dragonfly 
(hasn't flown yet) and found the construction technique to be fast and easy 
(you have to be fast when applying epoxy).  However, I want to start over with 
a conventional design that fits the requirements of E-LSA.  I would like to use 
the same construction techniques used in the D-fly but do not know what the 
parameters or results of putting a hollow space inside of a foam core wing 
would be but think it might be doable as wing tip tanks, just hollow out the 
outermost 'x' inches of wing and use it as the tank, the least stress place in 
the wing. I am looking at the KR design as the basis for this plane and soaking 
up any ideas I can run across to help me out.  Perhaps external tip tanks a la 
T33?  I am aware that foam dissolves in gasoline..

KR> Wing tanks/Fred Keller

[laser...@juno.com]

My first KR had 12.5 gallon tanks per side plus a 12 gallon header.  With
the Revmaster and Maloof CS prop I had 1200 SM range with reserves.  I
remember filling all the tanks and taking off without problem - with just
me in it.  It was the "standard" KR and was really only suitable for one
person sitting in the center.  That gave head room and elbow room too. 
Feet on the outboard rudder pedals.  Center stick.  Very nice.

Fred's KR is hanging in the Museum of Alaska, Transportation and Industry
in Wasilla.  If you look way in the back at the picture below, you can
see it.

It's not just about bladder as Mark pointed out in an earlier 
post.  He can now make cross country trips, out and back, without 
refueling.  I carry 4 hours of fuel (25 gal) and on my longest cross 
country to date I made a fuel stop after two hours to stretch and 
purchase some cheap auto fuel.

My tanks are in the outboard wing panels only, 12.5 gallon in each 
wing and no header tank.  They run from root to tip and extend only 
10 inches behind the forward spar.  From full to empty tanks my C.G. 
shifts forward 1 inch.  I seldom run them completely full.  Most of 
my local flying is done with 1/4 to 3/4 full tanks.  I use two 
electric fuel pumps that can pump from either or both tanks, no 
engine driven fuel pump.  I also have a small (4 AH) backup battery 
in case I lose my electrical system.  That happened once and the 
backup battery kept the engine running without a miss.  385+ hours 
and no problems in spite of the fact that many said it couldn't be 
done.  On a 7 foot long tank you'll want to make sure it is well 
baffled to eliminate any slosh.

KR> training

[Ray Fuenzalida]

Hello All,
Just wanted to toss in my most recent experience and the value that I got out 
of it.  I know some of you guys out there (it feels like most of you) are 
experienced mechanics, fiberglass repairmen or aviation engineers.  For people 
like me who are real estate guys it has been a big learning curve and I believe 
I am still on the bottom end of the slope.  But I have learned a lot and I 
expect to learn more.
 
I am  a part owner of  a Beechcraft Sundowner and my partner is a new A 
(retired from Monsanto so this is his 2nd career) and together with an IA we 
did a complete annual this past weekend.  I believe I was the willing slave 
labor for the job.  But the important part is that I learned a great deal this 
weekend.  I have always believed you learn much more by doing something as 
opposed to reading about it, listening to someone tell you about it or even 
watching someone do it.
So I am now somewhat of an expert on repacking wheel bearings, changing brake 
pads, replacing the wheels and disassembling just about every inspection plate 
on the plane.  We had a fuel leak in the selector valve and I actually swapped 
it out.  So my hands & fingers are scarred up and a little stiff from fighting 
to get to the nuts/fittings holding it in. We had to defuel the plane and more. 
 It was great.
The bottom line is that I am infinitely more familiar with this plane than I 
was last week.  I have learned a great deal and will be much more confident 
working on my KR2S. 
Things I didn't know about include items such as during the compression test, 
the prop can spin and give you a good whack on the head.  Without being warned 
in advance it could have easily happened to me.  But now I do know how to 
"feel" for top dead center.  What other little things to watch out for do I not 
know?  I will continue to try and find out.
 
Anyway, I feel a whole lot better about myself and that I may be more capable 
than I was giving myself credit for.  Education and experience are wonderful 
things.  As I get more, I get more excited about what I can do with this KR2S 
and it seems really possible.
 
I encourage all of you who have doubts about your abilities, volunteer to be 
the labor in any inspection/job and you will be the better for it.  I know a 
guy about to do some fiberglass work on his speedboat.  I intend to learn all 
about fiberglassing there.
 
Keep working.  I intend to.

Don't dispare, Sid.  I originally built a large header tank, and then 
worried that all that weight would eat into my gross weight and cut into my 
passenger/baggage weight, so I eliminated the header tank which just left an 
8 gallon tank in each wing.  That isn't enough!  But that was before I knew 
that gross weight is set by the builder (mine is 1200 pounds) and the stock 
properly built KR with a big engine can handle that.  So now I've added 
another 8 gallon tank for a total of 24, and that lets me do things like 
flly to my father's place, land for lunch, and fly back, without the hassle 
(and danger) of driving to the gas station with a potentially dirty old gas 
can to buy who-knows-what octane gas from the country store, and then "test" 
it on climbout from a grass strip surrounded by trees.  And that extra 
capacity lets me fly home from OSH or somewhere at high altitude without 
burning up time and fuel while climbing back after a mid-journey fuel stop.

Just because you've got a lot of fuel tank volume doesn't mean you have to 
keep those tanks filled all the time. I don't.  I keep the outboard tank 
empty unless I know I'm going to need it.   But when you need it for the 
"right mission", you've got it...

Yes Paul. I believe my old 1970's plans has an alternative engine 
installation print that has a drive pulley on the flywheel turning a slick 
magneto. My brother-in-law put an alternator in place of the mag. This was 
done in the rear tho.

Yes, why not put it on the market?  Can it be calibrated?  Do you have pics

I don't need it, but every KR builder out there could use something simple
and in-expensive.

I designed and built my own capacitive fuel gauge on N54PB and it works 
great, very accurate.  I designed the baffle as a large capacitor inside the

tank.

KR> outboard wing tanks

[John Martindale]

Craig, yes they have. Search the archives. Spin recovery with the extra
weight on the tips versus rudder effectiveness, aileron effectiveness in
lifting the tip at low airspeeds and fuel lift from the lower tank in an
unbalanced steep turn are two issues to think hard about. Also if you drop a
wing on landing the tip is the last place you want leaks and sparks. You can
get well over 100 litres in the standard KR tank plus stub tanks and the
inner part of the outer wing between spars. That's 4 to 5 hours flying
depending on your engine size..why go to tip tanks??

Still thinking about fuel tanks.  I have seen at least 3 KR's in South
Africa with tip tanks.  It's a thought but I was looking at my RAF48 skins
and wondered if anyone has used the wing outboard of the spars to create an
internal tank.  My rough calc puts the volume at 10 gallons.
