I recently purchased a Kraton 6s in May, and I just had my motor start smoking. I opened it and figured out that a bearing had exploded and pretty much trashed most of the inside of the motor. Is this covered by Arrmas warranty?
Contact where you got it from they should be able to sort it.
May take a few weeks there not that quick in the UK not sure where you are.
Keep an eye on your ESC when you get your motor back.
Had my ESC catch fire and arrma say it may have been caused when my motor bearing went.
