KR> Inline kr's

[The Ainsworths]

J Sellars in New Bruswick had 2 KR s for sale and one had a small inline 
Saturn 1.8 chev w/ re-drive with a  'hot' set-up. I think they are sold but 
he may still be available on the list and had a couple of photos of his KRs 
which may be of help. Check the archives and send an  email

KR> Spring trim system

[Jeff Scott]

I flew a Sonex with that exact trim system in it for about an hour this 
morning. Very nice flying plane. Flies very much like the KR except the 
elevator is significantly heavier and the ailerons quite a bit lighter. The 
only thing about the plane that I didn't like was the trim system. As the 
aerodynamic loads would go up at speed, the loads would stretch the trim 
spring, so it just didn't want to trim up. But as soon as you would start 
slowing down, with a lesser load on the elevator, the spring would contract and 
the plane wanted to keep pitching up. The more I slowed down, the more it 
pitched up, which cause it to slow down and pitch up even more. In effect, when 
you wanted to go fast, it didn't have enough nose up trim, and when you wanted 
to climb, it didn't have enough nose down trim. The owner says the trim system 
is one of the few things they plan to change on the plane. I should mention 
that the trim works much better with a more forward CG. When the owner flies 
the plane, he's flying with the CG at the forward limit. The trim works much 
better in that scenario. With me on board, we were flying right in the middle 
of the CG range. The trim was more of an annoying distraction than it was 
effective. 

 This is the fourth plane I have flown with a spring type trim system, all 4 
different designs. Probably the most effective one I've flown was in the Piper 
Tomahawk, the second most effective was the spring trim system on some of the 
GlasAirs. The one on my KR is the least effective and will be replaced with a 
trim tab next time I do major surgery on the plane. The one on the Sonex is 
easily the most annoying. Of the four different spring trim systems I have 
flown, none are as effective as the simple trim tab you find on most aircraft.

 http://www.sonexaircraft.com/orders/trimfaq.html Has anyone used the Sonex 
trim system in their KR? I have convinced myself that the this is a good system 
and want to try it. Craig www.kr2seafury.com

KR> Re: KR2 spars

[Phillip E. Harrison]

Greg,   
I am working on a kr2 project. I brought it to University of Alabama
where the engineering guru's and their students are using it as a learning
tool.
One of the things they are exploring is composite spars with
removable out board wing sections using the as5048/46. They will build wing
spar with wing attach to test. I will be glad to share the results.
They also have decided to go with retractable gear. So I can offer
you / ( kr netters) the fixed gear, wheels...
Question: I see there is a combined 48/45 wing template set has
anyone built a 48/46?   Does anyone have insight/suggestions on this
combination?

The Lancair 320/360 and the Pulsar XP have all composite construction, fuel 
in the wings and removable wings.  The Lancair wing spars are attached with 
only two bolts for both wings at the two common attachment points inside the

fuselage.

Hi Dave

Many thanks the reply. I am well familiar with the KR2 Super and its 
website, have been studying it since February of this year as well as many 
other KR builders sites.

I like the KR2Super very much and building with composites is no problem for

me - been doing for about ten years for model RC planes ( a different story 
but composites are not new to me). As usual one sets out with a plan and a 
list of desires which normally are not fulfilled in every way by existing 
designs - in other words one tends to like different things about different 
designs but never finds the "ultimate solution". So I want a two seat, side 
by side and homebuilt from plans. It would be great if it could fit into LSA

limits (again a wishful thought). That led me to KR and the KR2S. Further 
research led me to alternative materials due to wood availability in my 
country. I found the KR Super and got excited.

Trouble for me though is I want the original wing design with WAF's, fixed 
undercarriage, fuel tanks in the stub wings and I want to put it onto a 
trailer to take home in winter and save storage cost for fuel! Scott's KR2 
Super does not allow for this with his spar design. I also like the way Mark

has rebuilt his wings - from the fotos it is a far simpler construction the 
the Supers but he used "beefed up" woodens spars.

I also find nothing difficult/complicated about the Supers spar design - 
website has excellent instructions, very good foto's and if followed 
correctly and taking care with the layups and methods an easy part to make.

I am by no means a designer and would be lying if I said I understood half 
the technical discussion on spar design so was hoping to compare what I have

found out and worked with to someone else who may be more familiar with the 
design aspects of a spar.

So back to my original question/query - has anyone designed alternative 
composite wing spars using the original WAF's mountings design idea?

thanks again

Greg
