That is along the lines that I was thinking, but is the "too much engine" mean that it has too much power for the size of the aircraft? For illustration...what happens when you put too powerful of an engine on a plane? Worst case senario of couse. Would the torque cause ground loops, torque rolls in horizontal flight, etc?

#2 Here is a new question, the model has the crank line shown to be dead center of the firewall with the motor in the upright position. What effect would it have if I were to invert the engine and move it closer to the top of the firewall? I'd pick up alot of ground clearance and move the head away from the ground also. Let me hear your thoughts on that one also.

thanks again,
