Flips on Takeoff

Hello everyone, I’m new at this and just finished building 450mm Pi/Navio2 UAV. I have been unable to launch it successfully, as it tips to its forward starboard corner and flips. ARDUCOPTER 3.6 is what is in use. Things I have checked during the troubleshooting:

  1. ESC control wiring / NAVIO2 connections - #1 Fwd Stbd, #2 Aft Port, #3 Fwd Port, #4 Aft Stbd
  2. Motor rotation direction and prop orientation. #1 and #2 are CCW, #3 and #4 are CW.
  3. I have changed micro usb cards to a 32 GB U3 Sandisk. (with a fresh image)
  4. I have recalibrated the ESCs by plugging them into #3 on the Rx powering up with full throttle…etc.
  5. I’ve been through the setup several times and have also reloaded default parameters.

I tried to attach the .bin file but new users do not have that privilege. Any help would be greatly appreciated.


Found the problem…one faulty ESC.
