I had a chance to fly mine today, and I love it, I installed the engine with the suplied 2 1/2 inch stand offs and it flies fine, I am using hitec 5645 on everything, except rudder, on the rudder I am using a jr 8611, no cables, I balanced it with a jr 3000 mah battery behind the tube, against the radio tray, I think after the engine gets broken in I'll move the battery back maybe about an inch or more. For power, DA 50 with tunned pipe, awesome!!
