been flying for about 4 years now and ive accumulated a pile of motors with burned out windings, mostly from crashes where the motor got dragged along the ground with a prop still spinning, you know how it is. someone on another forum mentioned rewinding them yourself and i looked up some videos and it seems doable but also incredibly tedious

the motors in question are mostly 2207s from a few different brands, nothing exotic. i get that for like a $15 motor it probably doesnt make financial sense but im kind of curious from a pure skills standpoint and also i have like 8 of these things sitting in a drawer doing nothing. has anyone here actually done it and was the result anywhere close to a factory wind in terms of performance? im assuming the turn count and wire gauge are the main variables but i dont really know what im doing yet

also wondering if theres any way to test a rewound motor properly before just chucking it on a quad and flying

ive done a few rewinds, its genuinely satisfying but yeah it takes forever the first time. you need decent magnet wire and the patience to keep your tension consistent throughout or you'll end up with uneven coils and the motor will vibrate like crazy. for a 2207 i'd say budget a few hours your first attempt, maybe more

in terms of perofrmance it can actually be pretty good if you nail the wind, some people do custom winds to shift the kv up or down which is kinda cool. for testing i just prop it up in a bench mount and do a slow sweep on the throttle listening for anything weird, then check temperatures after running it for a minute or so. not super scientific but it works well enough

i tried once and gave up halfway through, the wire kept slipping and i didnt have anything to hold the stator properly. probably need a proper jig setup. for what its worth i think the skill is cool to have but realistically used motors in good condition go for almost nothing on the usual facebook groups so its hard to justify the time unless youre really into it as a hobby within the hobby sort of thing
