Mine balanced out fine, without much adjusting. Check out the following:

1. Are your servos down near the tail?

2. Is the wing in the right spot?

3.Are the Rx and battery tucked in the leading edge of the wing?

4. Did you use 1/16 inch wall tubing?

5. Can you move your landing gear forward?

Basically, is everythng as far forward as it can be?
