So hey my kid bent a rear axle link bar and the axle was tweeked so the drive shaft was going through universal joints like a kid with candy then the gear bor went leaving metal shavings in the motor. So I contacted the Red Cat company and they said oh yeah we get these calls all the time. Red cat uses cheap drive trains. After we hung up I called amazon where I bought it to find out he had already called and said I wrecked it and they won't help me cover it. Well after telling amazon my side of things they decided to help filling a a to z claim to get me a full refund. Ha jokes on them. Anyway the point to all this is don't buy Red Cat.
