Quadcopter Launches unevenly

Posted by Jerry Suhrstedt on April 6, 2015 at 9:49pm

Built a new copter, here's what I got:

  • 550 wide quad frame
  • Turnigy 950 KV motors
  • Afro 30 A ESC's
  • Arducopter 2.6
  • Turnigy 9X Transmitter / Receiver

------------------------------

Installed latest firmware.  Went thru entire Mission Planner setup wizard... calibrated GPS, compass, radio transmitter, etc.

When copter starts to take off, one side of the copter starts to tip over and then if I give it enough throttle it will pick up and finally get airborne.

When running in LOITER, seems to hover pretty stable.  But then again the LOITER feature is probably compensating for some of the motors.

Is this an APM issue?  ESC issue?

    Jerry sorry this isn't an answer to your issues but have you made any progress on this? I can't understand it. Thx.

      Always turn the transmitter on first throttle closed, well done on having the props off. I don't know anything about Afro ESCs but I would have expected battery size tones so something there is awry.

        Gary I'm running 3.1.5 apm fw and when I calibrated my escs I didn't have these tones either. I had the same tones as jerry actually.
