It’s not that difficult/expensive to replace the RC’s micro USB socket.
As yet, I’ve never needed to (for my MP - but same controller, physically), but reports some time ago (almost 3 years) of others having problems I decided to get the part ready, in case.
Plenty of videos on YT showing how easy, and the part (a complete internal ribbon cable) was pretty cheap.
Bought on eBay for £16.27 (July '19).
My batteries are not holding a charge so well, these days, so will probably do both at the same time … when I get around to it.
