I'm not a big forum guy but after a hard crash which left me with a broken RHS front arm on my DJI mini 4 pro I thought I'd better pick the brains of guys much smarter than myself in the hope that I'll learn where to buy the replacement part. YouTube has been a great source of information but it falls short on some things. Now I'm off to try and work out how this site is laid out and navigate my way through it without making myself look too much of a dope.
