KR> Re: tubular wing tanks

[pk.sm...@bigpond.net.au]

If you did ... the technique for getting the PVC pipe out is as follows. To 
allow the glass to release over a long run first lay a single layer of light 
glass over the PVC and let it cure. Cut through this layer and move it around 
till it is released down the full length then reposition where you started. 
This is now ready for the final layers of glass for easy removal of the pipe. 
All you need to do now is fill in the ends. 
I'm going to use this technique for CF torque tubes.

KR> Re: tubular wing tanks

[Glenda McElwee]

Bill Clapp has developed an alum.version of his original PVC tanks.  I believe 
he still has the PVC tanks in his plane.  Most people have not noticed any 
smell from fuel unless the tank is full and the vent is overflowing.  

I have the same PVC tanks in my wings.   Alum tanks will affect embedded 
antennas in the wings.

Sloshing is NOT an issue in a tubular tank.  The Yankees uses long tubular

I'm in the final stage of preparing my KR-2S for inspection. This is a plane
I purchased 95% complete, I didn't do mst of the build.

I am concerned about the gap between the canopy and the body forward of the
canopy. I have a gap all the way across the plane, which is just under 1
inch at it's widest point.

Is this a common prolem?

Is it a problem at all?

Any recommendations as to how to address it?

KR> Taxi Tests WARNING !!!

[George Kolasinski]

Mark -- I'll second this comment.  I have a friend with a Ferguson
ultralight wanted to do some taxiing a couple of years back after rebuilding
his craft  .Didn't have the wing on  but did have rudder.   It  Didn't
travel more than a fifty feet and was airbourne and on it side very
quickly,.  Six months of hard work down the drain, a lot of money and more
time to rebuild  (one year more) before it flew again.  Very luck the engine
and prop was in back of him.

Hi guys and girls; 



OK, I have had time to review my use of the KRnet search engine and it does

I also apologize to the members of the KRnet list for stirring things up

Greetings Neal:
I just had to reply to your post and say that you have more nerve than I 
dosmile...
I don't believe I could taxi at your reported speed with no wings, and in 
addition allow the tail wheel to get lightie: less noise..., I would 
have liked to have been there. Rock on
I  am interested what you find/decide with your second ignition and the 
timing etc.
I have the same setup as you, (I purchased, did not build my plane) and do 
not have the timing info.  Just today I am checking/cleaning my plugs and 
replacing wires.  In my last flight, I noticed a vibration that I believe is 
new.  I only have about a dozen short flights and am just beginning to calm 
down and notice things other than my white knuckles...
I would like to have the timing procedure for the mag alsoIt is probably 
in the archives, I just have not looked yet.
Any how, good luck and take care.

KR> Re: aluminum wing tanks

[Mark Langford]

Here's a post from the KRnet archive from Oct 23, 2007:

"I got the 5" Alum. tube from "Hastings Pipe", Hastings NE, last spring for 
$114 delivered for (4) 5 ft lengths.  The price is now higher because of the 
increase of  aluminum and freight rates.  You should be able to find the 
material closer at hand from a manufacturer of aluminum irrigation tubing."

I bought some last year, and it is 5000 series aluminnum.  The website is 
http://www.hipco-ne.com/ .  Even though we have all kinds of irrigation 
systems around, and you'd think somebody somewhere would have some damaged 
pieces you could cut a section out of, I was unable to turn  up any. 
Anyway, I plan to install some simply baffles space with tubing, weld end 
caps and AN outlets on it, and  install a 4 gallon wing tank in my right 
wing if I live long enough to find the time...

I'm not sure if this will make any difference with regards to "slosh",
but I believe the Yankee has a steeper wing dihedral than the KR.

Level at the longerons.  I understand that is what the plans say, and maybe
I read it there myself, but that is also what I have been told and what I
have used.  So, I simply put a level on the shelf behind the seat and set
the plane to level.

I have questioned that, thinking that maybe it should be with the mean chord
leveled, but was told no, it was at the longerons.
