Ailerons 12-18mm
Elevator 40-45mm
flaps 20-25 for take off and 60mm for landing
CG for me is 22mm behind front spar, until I moved it back to there I had a bad nose tuck in tight turns. Now it is a ball to fly.
This was exactly my experience. Hard to stabilize on the approach, too. I almost gave up on the plane after a few flights until I moved the CG back.
