I think you're right. The last stunt contest, here in S Ca was cancelled. Next one I'm going to make a list and listen to each engine and how it breaks. I remember listening to stunters and each engine has it's own breaking characteristics and sound-kind of like the difference between a hot rod 301 CI mouse and a 350 CI. or a 500 inch rat.
A plain bearing engine would be ideal in this application, reduce weight and radically improve performance! I'm seeing a nice, dialed in OS 46. I'd double the control surface area, use a 1/2 A control horn and matching adjustable pushrod, And then I'd have an adjustable rudder to get it dialed in, and then fix the rudder.
And aspeed, how much would you want this bird to weigh?
