Please Help - ZMR250 Throttle Curve Problem

    I am having a problem with my new racing drone. It was bought as a kit from eBay, all new parts. I am new at this, so I don't know if I am doing something wrong or not.

    The problem:
    The Naze boots up and the motors chime, then I arm it. Here's where it starts to go wrong.
    When I raise the throttle, to any level, all 4 motors spin. Then 2 & 4 slowly stop with 1 at a steady pace, and 3 redlining, raising in pitch and pace until at max. I cannot stop this problem. I suspect it has something to do with PIDs, but I have no idea what to do with those. Please help me with this problem! Thanks, Toby.

    My Specs:
    - 4x Readytosky 2300Kv motors
    -4x BLHeli 20A Oneshot125 ESCs
    -Naze32 Rev6 FC
    -OrangeRX R610 V2 DSM2 CPPM Reciever
    -Turnigy 2200mah 25c 3s Battery

    That's pretty common if the quad is just sitting there (not in the air.)

    Redo your ESC calibration, you can also do it one at a time.


    It you have the nerve, and are positive you have the correct motor rotation and props, try getting it off the ground.

    I have tried to fly it. It does the same thing. I have sent the quad to a quadcopter repair shop. I hope they can fix it

    It flies now! The ESCs weren't calibrated. Now it works, this post can be taken down by someone now :)
