i bought the p 2 with the zenmuse factory package from amazon and used it without the gimbal for a couple of days and now that i feel comfortable i installed the gimbal and it does not point all the way down. after reading a lot of post about dead gimbals afar f.w. updates i am not sure i should even try that. i did the update on the p-2 and everything else looked updated..but that was before i added the gimbal. any ideas of why it would not go fully down?
