So would the fiberglass shafts and 4-40 rods in the y-fork arrangement be stiff enough on it's own, or would that need some intermediate support along the shaft? With the y-fork, it seems like on some models if you push on one elevator half, the other one moves opposite because the long shaft is getting pushed sideways. Or could it be that I am overestimating how stiff the setup needs to be on a 40 size plane?
Oh, and what about just running two elevator servos? Would that add too much weight?
