I consider my skybolt powered correctly with the saito 120 and the 108 would probably work just as nicely. They come out on the heavy side and have lots of roll coupling when rudder is applied. I dont consider this a 3d plane. The wing attachments are fairly solid but would never hold up to lots of blenders. Hovering for mine is difficult because of torque pullover and rudder coupling. snaps and spins nicely. If you want smoke you have to plan on moving the servos back into the tail as much as possible. There is not much room left at all when set up per plans.
