Well, it’s back together Bit tense, I can’t believe I didn’t damage that ribbon cable. Unfortunately one of the body screws suffered a stripped head but I just managed to get it out with a small screw extractor. Got it all back together and it reported that Compass One was disconnected - the GPS plug had come adrift.
Getting the case back on a second time was a bit of a strain as well, worried about breaking it, but I’ve just seen they are less than £10 to buy! A full screw set is £17, so I will live without one of the screws under the battery for now. I don’t know is the new rubbers are that much better, after all that, but it was a good experience - I now feel if I had a crash it wouldn’t be the end of the drone
Thanks for the tips,
