Some more questions... which one?

[jnev]

Well, I got my order from Mike. I got the 9xl motor, black heatsink, 19t pinion, and a UBEC. I am still waiting for an MM, Hyperion charger and balancer, and a 4s battery.

My question was, what do you use to make a slot in the motor "pin thing" (forgot name) for the pinion to sit in. How deep should I make it also? I was thinking either to dremel the slot, or file it down, which will take really long. I was also thinking to go down about a 1/3... is this enough, or too much? Also, the motor didn't come with any screws, what kind of screws do I use to secure the motor?

Thanks
