    Hi guys,

    Received my very own P2V+ yesterday and got a couple of hours with it. Very happy of course.

    Unfortunately I managed to crash it into a tree today (pilot error). Apart from a little bent in the frame the gimbal is hanging from (so not the gimbal itself) everything appears to be fine. However when I turn the P2V+ on the gimbal starts to behave erratically, it's spastically moving both its motors from end to end. It's like it's trying to spin the camera 360 degrees...

    I tried hooking the phantom up to my PC and the values in the IMU calibrations window show the gimbal going crazy. I tried to do basic and advanced calibration but no joy. I tried to reflash the firmware, no joy. Do you guys have any idea on what to do next? Or should I go buy a new gimbal.......?

    Thanks!

    post some pictures of the damage.. maybe you can straighten the plate? perhaps it's freaking out because there are sensors that are getting bad data because of the incorrect shape of things..

    (The green stuff is grass, yes)

    I suppose the best way to get it straightened would be to take the gimbal off and then the plate and bend it back straight. I'll try that later if there is no other solution.

    A video of the gimbal going crazy...

    The weird thing is, the drone doesn't really give an error. I can still take off...

    So, I figured my problem has to be mechanical since all firmware/software updating proceeds as normal. I took the gimbal apart (hey, it's broken due to pilot error anyways) and it seems the axis/spindle (English is not my native language, sorry) is crooked. I think the unexpected resistance during reset is causing a software panic of some sort. I'm not really sure how to fix this yet, the tools I need to investigate further are in my car. I will keep you posted when I continue investigating (it's bedtime in Europe).

    By any chance, is there anyone who knows what brand/type of motors they are using in these gimbals? Swapping the motor will be the quickest fix I guess...
