I used a Satio 150 and it was a bit much, and it was one hell of a performer! I liked the fact that I could use a larger prop and manage the power setting with the throttle. Personally I think the Saito 1.00 would be enough. The Satio 1.50 I used balanced perfectly - no weight anywhere! My bird was an 8 channel and weighed just over 12 lbs. With flaps it landed fine.
