Rob, how do you mix in differential aileron and can you give an example of adverse yaw? I've never heard of it before.

Doug, I've been to you website and seen your pictures. Where and how did you put in your aileron servos? Do you have a diagram or picture of it? It looks like you drilled a hole for the servo lead in the inner most 4 ribs.

lnorris, did you want to lose the wingtip's because of it's looks?

When I went home at lunch I did find something out. I won't be able to mount the 46 exactly 90 degree's and still be centered on the thrust line. The stock muffler on the TTPro 46 would go through the fuselage. As I see it I have 3 options: 1)use different muffler, 2) mount the engine about 75 degrees or maybe 105 degree's off vertical, or 3) drop the engine 1/2"-1" below the thrust line.

What would happen if the engine was 3/4" below the thrust line?
