RE: ZDZ GONE BAD!!!!!
There it it, Tex. Read it and weep.
That 115 will only require a little throttle management and the addition of a throttle curve in the transmitter to prevent pulling the wings off.
BTW, the 115 will balance in that new Sukhoi, just keep the rudder servo(s) and batteries as forward as the interior permits. I'm coming out pretty much on the money with the Brison and a dual rudder tray placed aft as you've already seen. A metal spinner would assure an easy balance. The most you will have to do is cut a new opening in the tray for the rudder servo. Piece of cake!
