Playboy
Peter,
I dug out the plans and here is the info. By the way, the plans I use were for an RC conversion of the Playboy Senior, published in RCM magazine. Its a faithfull copy of the original, save for the moveable tail surfaces.
My stabaliser is set at 0 degrees. My wing is set so the leading edge is 1/4" higher than the trailing edge when sitting on the pylon, this measurement is relative to the centerline running through the fuselage. Dont know what angle that is but probably about 3 to 4 degrees positive.
Engine is set at zero.
The balance point is 45 to 50% back, actually mine balances right on the small lower spar behind the main spar, if you know which one I mean.
5 pounds is a bit heavier than mine (I believe mine is about 4.5) but it should fly fine with that big wing.
Hope that helps!
