I have a few questions dealing with the plane.  I two engines to choose from the thunder tiger pro .46 or the magnum .40 both two strokes. Anyone have experience with these and can tell me what i could expect if i used one or the other? Another question i have is what servo torque would be acceptable for the plane.  I was wondering a standard servo with ~45oz-in would work? I plan on slow flight seeing this is a 3-d airplane. 

Thanks so much for everyone's help thus far!
