It doesn't look too good, does it? I've seen a number of videos of this aircraft (Reaper) with varying results. I questioned the position of the CG on a couple of them and received no replies. Mine is balanced at 2-1/8 inches from the leading edge. One guy said he had it balanced at the leading edge. I also agree that the rudder is virtually useless, due to its size.
I had an engineer friend of mine check the CG position and he agreed with what I have. Wing loading is in the warbird territory at 26.5 and cube loading is 13.70. We'll see what happens. In the meantime I'm going to reduce the aileron throws.
