KR>KR Questions - Stick Control - Prop
Looks like it will be official.. I will be a KR Builder by the end of the weekend, I am purchasing a partially completed kit and will be hauling it home this weekend! A couple of quick questions from a beginning KR builder!- >From the article Mark Langford put up on his website (I think by Neal) - it appears that the stick control is over sensitive - 3/4" in either direction is all that is needed to fly the KR most of the time. It would seem that it would make sense to shorten the hinge length/bellcrank distance so it would not be so sensitive, or have a progressive linkage if you couldn't get full motion out of the ailerons in a reasonable motion length... Also on the corvair aircraft engine, it seems like the RPMs for aircraft are lower and a higher RPM could yield a lot more horsepower. I understand the prop tip speed limitation, but would it make sense to have a shorter diameter prop with more blades? would that allow higher rpm and still obtain the same bite, without exceeding the maximum efficient tip speed??? I see the composite propellers often could have up to six blades - was just thinking about four! John Monday Laguna Beach CA jsmon...@aol.com

What a coincidence! I also am picking up a partially completed kit this weekend. Although mine is in Florida and I am bringing it back to New Orleans. I have just started reading the KR emails, so I hope to get up to speed soon. Good luck on yours. Ray jsmon...@aol.com wrote: Looks like it will be official..

About that corvair. Go here http://home.hiwaay.net/~langford/corvair/index.html Keep in mind that WW found that 100 and 120HP is the max HP it can produce and be reliable. I would like to have a CS prop and be able to spin the engine faster for take off and such but time will tell.
