DHC - The snap roll isn't at full elevator. It's in mild right turns. I didn't use the dowel. I used separate elevator servos of 52 oz/in each. I'm really hoping the snap roll is just a CG problem. The CG is in the range suggested but at the forward edge of it. I need to use a lighter engine.

I plan to spend some time with it in the future and try to work it out. I'll revisit this thead when I get there and describe what I did and what happened.
