    Hello,

    I upgraded the firmware on my P3S and now get an IMU Calibration error. When I try to calibrate I get to 2% on my android and it stops. I tried to calibrate from an iPad and it gets to 1% and stops. When I called support they told me to downgrade the firmware using the app but after holding down the graduation cap it tells me "No available firmware for downgrade."

    Does anyone have any other options for downgrading?

    Thanks,
    Ospreybill

    Welcome to the forum .
    I haven't never tried to see that but do you have your bird powered up when you push that hat down . It might have to be on .

    I upgraded to 1.6.80 and tested it at the local park and everything was fine. Drove down to the beach and it wouldn't spin the props without an Imu calibration. I wasn't really prepared for that. I just sat it down level as I could. It calibrated in a couple of minutes and has been flying fine since. Anybody notice that RTH speed seems higher now? Before I never saw more than 22.5 mph but now its 31.5
