Well, I have a new mini-z and I have already adjusted the space between the motor and the motor clip with paper. But now, my motor, even without connceted in the gears, make a year sound and the rotation slow... What should I do? Would a oil fix it??

I Put some oil in the end of the motor's shaft, but it didn't work well. My motor just didn't gas more. So, I cleaned it and it began to work again, but it smell burn. I Just want to know with it can burn my ESC.... I will appreciate a reply...
how bout changing the motor? it will work
