Hi,
Update
Thank you for the advice. I tried Drone Doctor and was told that the model is too old. So I've bitten the bullet and attempted DIY. Not total disassembly as that looks way too hard, but some minor surgery.
I actually managed to pry...
Thank you for the reply.
I already DO have a replacement arm, it's the one in the second pic. It is the wire on the replacement arm that I am considering snipping to release the broken mounting clip. I would like to disassemble the foot itself...
I bought a Mavic Air in 2018 and, to be honest haven't used it all that much. I have managed to break one of the arms and now no authorised repairer will touch it. The damage is tiny, just to the small bit of circular plastic that holds the foot...
