Flaperons, GP Pitts Special
Has anyone tried this. If so, both wings? one wing? Will it work? I have a T6AXs and have the ability to chose one wing or both for flaperons. What's your opinion?
Thanks,

I would say that your thinking is correct in that it would, or should add some low speed lift, but with barn door style flaps, it changes the wing's tip incidence relative to the wing's root incidence, in exactly the opposite direction that is needed for low speed stability and enhances the potential for tip stall. hence, the reason strip ailerons are preferred.

I agree that attempting flaperons on a Pitts is almost certainly result in a Monokote bag of busted up wood. I am going out on a limb and guess that the reason for wanting to do this is that the airplane is landing faster then what you feel it should. My question is where is the CG and have any flight tests been done to evaluate the CG position? My first impression is that if the airplane is landing fast is that the CG is on the forward side and a major contributor to the landing characteristics.

it's an unfortunate characteristic of rc biplanes that they get a bit on the heavy side for their wing area. that results in low glide rates and relatively fast landing speeds. it might just be something you have to live with. pushing the CG back often results in a dynamically tail heavy condition, as well, making tail response sluggish and dangerous.
