My Copter Lends to a Side in TakeOff

Hi

My QuadCopter always tries to go to back and left of it. It's APM2 with ArduCopter 2.8.1 firmware.

It happens a lot to me, mostly in all my hexa, octa and quad copters I've built. I never tried to fix it, because I mostly fly using Auto mode. But recently I decided to try a little Stabilize and I see ALWAYS my quad tries to go to back and left side of it. When it takes off a little from ground, it start going to that side.

What do you think it's cause?

I tried to test CG with a wire in center of my frame, using a single wire my copter stands center.

I always do PreFlight calibration before take off on any land.

Still same.

Any ideas? Suggestions?

  • Do you level your coptor before every takeoff?  I had a similar problem during my initial flight testing but found that a TX calibration followed by a Mission Planner Radio Calibration followed by a level on a "level" surface fixed the lean for all subsequent take-offs.

    I did my first bit of un-tethered flying today without doing a level at the field before takeoff and didn't have any problems.

    Should I be leveling at the field before each takeoff?  If so is there a command to level from the radio or can I program a switch?

  • If it's not a leveling problem, then it could be caused by vibration.
