This is sold as a Motor Repair Kit but all it is is 4 motor housings, no actual motors. They're well made but useless if what you're trying to do is replace a motor. Should be labelled Motor Housings to avoid confusion
Excellent service got them the next day just fited them to my drone. I had bent the old one's after crash causing my propellers to wobble like mad it works perfectly now and these are a lot cheaper than buying replacement motors thanks 😊
