Got a pair of cheap chineese 270 kv motors from diyeboard.com. About a year ago one of them lost torque and stopped spinnning properly. Now this has happened again to both my motors. Have they been overheated and lost functionality? they still wok but they are “weak”. Things ive tried:
No problem with ESC, changed that out.
New motor fixes the problem for a while
Any tips on how to avoid this? Im using 90 mm wheels and ride in steep hills. Is this caused because of bad motors or is it something else?

If you want to keep your gear ratio for 270kv, i have 2 propdrive 5060 270kv motors for sale. They are both nearly new. They had enough power to accelerate faster than i was comfortable with. Top speed was over 30 on 8s battery.
From what I gather, sometime a magnet can get loose in the motor and this will of course create some issues. As they are trash now anyway, you could try to open one up to inspect it.
