hadnt flown my p3p for a few weeks and came to it today no signal and no pic on tablet. Didn't upgrade fw or no change. No sd card in. So tried so card with my fw 1.4.10 Bin on it and it went dddd, dddd, dddd then after 1 min just contant beeeeeeepand had to switch off to stop and txt file said failed fw upgrade instead of usual fw already installed as bin or whatever is normal when SA,e bin is in so card. Any clues . Nothing in rc changed either or app. Really miffed as I have another p3p and the gimbal trans only works till it warms up, about 5 mins then stops signal to rc. In both cases so card records vid. Any advice on my first problem or am I loking at 2 fried gimbal boards and £600 for 2 new complete units. Anyone wanna buy the cameras?
