Help me!

[savagejac]

I have recently installed a novak havoc bruchless system into my car, but there has been a few problems. Once installed after about ten minutes of steady running it, the plastic spur gear attached to the motor has worn down. The gear had no wearings before so must be the motor. This is unbelievable. Is there a metal hop up as i dont want to be changing the gear every ten minutes! help please write back asap
