Corsair setup
 
Because of the lack of a manual I need to know the incident setting for stab & wing of a Kyosho Corsair 4Fu ARF, also the C.G. location.
55" wing span, OS 46 engine. Information will be appreciated.

Good luck. I have never seen a stab or wing incident published in an ARF manuel.

hellcat is right, i dont think you will get any incidence info in any ARTF build manual, just make the wing tip to stab tip distances 0 and the stab tip to ground (flat surface) 0 and fin tip to stab tip 0, you will be fine, the following link has some usefull info on cg for this plane, there is a lot of waffle in it, but look through and see. i had the phoenix corsair, flew beautifully till i had dumb fingers, be very very carfull on the elevator throws, on mine it was incredibly sensitive and the first flight almost gave me a heart attack.

hope this helps:

RE: Corsair setup
 
Thanks for the responses. the Corsair belongs to a club member that purchased it used, he asked me to test fly it.
After a thorough field check I thought it was a little nose heavy. On take off, up elevator, slowly adding throttle up to a good ground speed and when I eased the elevator to nuetral, it nosed right over quickly.( twice). I explained the changes he could make to correct the problem,(bend the landing gear forward & larger wheels, and that there may be some down trim in the elevator at nuetral). I wanted to try one more take off adding some up trim, he didn't want to chance it until the changes were made, and asked me to make the changes (what are friends for?)
After making the above changes I checked the incidents and the stab was at 0 degrees and the wing -.5 degrees, my thought was that this could have the caused the nose overs. I was going to raise the wing incidence to +1 degrees but wasn't sure that was correct, thereby the reason for my post.
I'll now change it to 0 degrees and leave it nose heavy for now before I try again.
