My Feigao 7XL siezed

Feigao's are fine motors for what they are. People just ask too much from an inexpensive motor when they toss a low turn version in a heavy truck and expect it to perform. It overheats, explodes, and then it's considered "sub par". Of course it's sub par, it's sub $100. If you use a proper KV for your setup so reasonable gearing can be used to reach a decent top speed, then they do quite well.

That's my 2c anyway. I grenaded the crap out of an 8xl. Not a pretty sight. There are plenty of better motors out there for just a bit more cash if you want to shoot for crazy speed. I just don't feel like a 6xl or 7xl is the choice for high speeds in a truck like Revo, or larger. If the vehicle is that big, and you need to go faster than an 8 or 9xl, then it may be time to drop on a more expensive motor.
