I am tuning my quadcopter(AC 2.5.4 X-Mode) with APM 2.0. What i noticed was always it tends lean backwards, Means nose tilts 15 to 30 degrees upwards, So constantly i need to move pitch stick to forward to keep it stable.I calibrated all the motors and also did the leveling of the copter in Mission Planner.
Also i tried to control with TX pitch trim FW/BW still no luck.
Did anybody had the same issue like me?..Pl's let me know how to resolve this.
I have couple of questions pl's clarify..
1.) After Leveling in mission planner should my Artificial Horizon center horizontal mark should aligned to zero?
2.) Is it possible that my APM2 board is not aligned properly?
What exactly causes this behavior and how to fix this..Experts help me.
