    I had a battery take a crap about 100 ft up and my QRX350 met the ground destroying the gimbal and the flight controller.

    I have rebuilt the quad with new body but the flight controller is toast and will not stay solid in flight.
    What flight controller can I replace the Devention FC with.

    Have you done a recalibration on the FC?

    I have a x350 pro needing a flight controller as well. been looking at the DJI naza lite. its about 90sd, has everything to replace the setup in the walkera, compass module, led, gps module etc..... also looking at the APM 2.6 with side pin connectors, also around $90. I think the apm has a 915Mhz telemetry add on for $25.

    I am going to have to read up on how to do that. I hope it works because I really liked the way that drone flew before tha accident.

    I have done recalibration on the drone and rebound the radio, and after arming, I noticed that one of the motors doesnt start up right away with the rest of them and the ground and the when it gets going I lift off and within seconds the drone flips over on the ground and loses the bind with the radio as indicated by the left light returning to blinking.

    Sounds like a wire is cracked in the ESC or motor wiring. you need to desolder one end or each wire one at a time and check it with a multimeter on resistance check while you wobble the wire.

    Cheers

    will a motor power on if one phase is out? yeah check the motor wires / solder joints

    its hard to tell, but each esc makes a beep at power up do all of yours?

    Not an electrician but I do believe these motors are only single phase.

    They have the equivalent of 3 phases.

    Not sure how comparable your QR X350 is to my Pro; however, If you are able to do so, I would recommend upgrading the Main Controller to the FCS-X4.
