hi, i have a apm2 (fw 2,9,1)on a turnigy hal frame, ntm3530 motors with graupner e-props 11x5 and 2 3s 3300 mah lipo.

my problem is that the quad keep going forward a little fast (when i do not touch the sticks) and accelerating if i do not compensate. I've tried to add some trim but doesnt help. 

i've done the calibration in mission planner, calibrated the esc (f30a reflashed) checked the aligment of the motors but there is always this tendency to move forward! what can i check also? maybe the apm is not parallel to the propellers plane? 

a big thanks to enyone will help...
