Some folk like to repair things, besides which he was interested in the batteries or battery (we are not sure if the crash battery was one of the two shown). A spare controller isn't a bad idea. You could even have a master /slave pairing.
I made a mistake once and sent a
Mavic 2 up for a quick spur of the moment flight, the master controller charge was low and it died in flight, more quickly than I thought it would, I swapped the phone over to the slave and all was well.
I bought a scrapper
Mini 2 for parts, sold as damaged shell and gimbal. I was lucky, it turned out only the shell was damaged, I changed that (middle shell) for one I had in a "bag of bits" and got a fully functional, low hours
Mini 2 for under £100. Just for clarity, I doubt the actual drone of this thread would have such an easy repair but the drone wasn't the OP's 'objective'.
