I have a new Scorpion motor for a 700 class heli. The flat on the shaft for the pinion grub screws is not were I need it for lining up the pinion properly to the main gear. I will be using a dremmel tool to create a flat on the motor shaft at the location needed for my set up.

This is my first time attempting this, and I was wondering if there are any tricks of the trade to do this correctly/easily? Also what attachment would be best to use? Grinding wheel, sanding wheel, cutting wheel, ect?

Thanks for any advice

Ive done it quite a few times, just use the sanding wheel and get it flat if there is two spots on the pinion do both

I like to put the motor in a plastic bag and stick the shaft out of the bag so when I'm grinding the metal shavings stay away from the magnets and the motor!

That is exactly what I do. Those shavings and metal dust go everywhere and the worst placed for it to land is inside electronics
I blow is out with compressed air to be absolutely sure

I wrap it in baby wipes just because the shavings stick to them and I happen to have babies

good thinking tho, but why would you have the motor sitting
where your shaving the iron. I remove the shafts and place it
on a clamp then dremmel lt.

it not hard if you got some nice metal bit and a clamp it easy
I use to send my motor back to scorpian for repair, once I watch the video and see how they do it, I never mail another one.

That's exactly what I did. I put it in a freezer bag, and shoved the shaft through the bag.

Thanks for the replies everyone.
