Got the Wingnetic motor (as a spare part from Hobbyking), more power and runs way cooler than the small motor I had previously put in (from the original Kinetic aka Merlin clone). With the heavier motor I need more weight in the rear, works well now with a 1000mA 3s 25C Nanotech. Important to have VERY small throws on the elevator, I recommend to move the pushrod all the way in on the servo horn.
