Les Palmer cut me an aluminum gear which copied Dan’s design. We made the gear an extra 2 inches longer. I wish I had done it from the very beginning. Sent from my iPhone > On Jan 22, 2019, at 10:17 PM, Kayak via KRnet wrote: > > I think the original retracts had a coolness factor. and no othe

I think the original retracts had a coolness factor. and no other advantages plus all the disadvantages you mentioned. I do recall from reading newsletters 30 years ago that the unlocking and broken bolts issues are fixable, but you still have less ground clearance and more drag not to mention for

Hello Randall, I'm going to convert to fixed landing gear & your performance figures look really good, what brand of kit did you use was it the Diehl landing gear ?. On 2019-01-22 05:26, Randall Smith via KRnet wrote: > I know when I started flying my KR it had retractable gear after the third

Sounds like Richard and I are on the same page. My 81 JM is also an original retractable light KR II. My instructions when I bought her 30 years ago was to fly the pattern at 80, over the fence at 60, touching down something below that. Works for me. Although I've tried three point landings, they d

Hi Mark. I have no first hand knowledge of a higher higher stall speed with the newer airfoils and just repeted what was stated in one of the recent posts on that subject. I also just checked the info on my KR-2 plans which calls the stall at 42 mph, and 52 mph for the KR-2S. I was never able to c

There are several good reasons for selecting fixed gear, but less drag is the one most difficult to prove because it requires that a well faired in retract be replaced with a well faired in fixed gear, and no other changes be made while the aircraft is down for the mod. There are quite a few KR peo

Make that "mistook the MIXTURE knob for the THROTTLE knob". I did proofread it the first time, but apparently not thoroughly enough! And shortly afterwards, I installed a completely different shaped and sized knob for the throttlenot just a different color! Mark Langford m...@n56ml.com htt

I know when I started flying my KR it had retractable gear after the third time the gear unlock while I’m landing I decided to go with a fixed gear. I actually picked up 5 to 7 kn with a fixed gear and wheels all fared in. Plus I picked up ground clearance on my prop. Sent from my iPhone > On

I've been following the airfoil thread and would like to add one thing. Almost every modification you make to the original design will have an up-stream or down-stream effect. Decisions on which airfoil you plan to use will likely effect the type landing gear you will be happy with. I chose the ret
