Pla,
You balance that plane 1 7/8ths" back from the leading edge, on the underside of the wing, "where it meets the fuselage".

Place a small mark on the wing, close to the fuse, then balance the plane with one fingertip on each mark. It should be level or slightly nose down.

NOW, the more you say, the more I believe this will be your first RC flight. You have NOT said anything about who is going to be helping you.

PLEASE do not try this by yourself. If you felt bad because someone broke the stab, how will you feel when you're using a trash bag to pick up all those little pieces?
