I would be very careful using press on pinions on a brushless Outrunner motor, the bearing, rotor hub and stator housing that it fits into can be crushed easily making the motor unusable. Twist the rotor before and after pinion installation to make sure it spins free and dosent bind. Slip on pinions can be used with Loctite 271, just let it cure for 24 hours for a good bond or solder the pinion on the shaft.

I've pressed a number of pinions on brushless motors with no problem. I use a small piece of steel to fill in the space on my pinion press because the motor is so short. So the end of the motor shaft is pressing against the steel and not being pressed into a hole in the pinion press.

 

I'm also the one who makes the little black mounting plate that snaps into the can that you see in the picture. I originally made them out of aluminum but they wouldn't allow the aluminum bracket to be run in the Michigan 24 because some people thought it would make the motor pod stronger. A regular motor in the motor pod makes the motor pod a lot stronger than a 3D printed can with an aluminum bracket snapped into it, but they didn't see it that way. So I started making them out of high impact plastic and they approved it because it was not metal. I'm now making them out of phenolic which is another plastic.
