Please help! Motor test and ESC Calibration

The APM “ESC” advanced parameter puts the copter in ESC calibration mode at next restart. So I guess you could:

  1. Remove all propellers in case this doesn’t work!
  2. Configure your joystick and ensure it appears as RC input.
  3. Set the ESC parameter to 1, “write parameters”, then reboot/restart APM.
  4. Connect and move the throttle up on the joystick, wait for some beeps, then back down and if you get the other beeps it worked.
  5. Moving the throttle up should then power up all motors at the same time (now synchronized). If one motor starts early/late then it didn’t work.

I haven’t tested that without a receiver, but in theory it should work. Also check the DIY Drones forum about the “ESC” parameter.
