I do it for free, because you never know when you might need a favor in return.
My lathe is an Integy for $89.00. works as good as the rest. I have some fun because my girlfriend is a tool and die maker. If some one asks me to cut their motor I just hand it to her and smile.
She does the comm so I have time to do other things. She also made me a really nice tweak station.
Just so you know Rez, its best to cut the arm (comm) when you change brushes. I have run a motor and worn out the brushes without doing anything, but more power is available if you keep your motor in top shape.
Get your motor running and spend your time and money behind the remote. Practice, Practice, Practice.
If you can drive 1/12, you will be able to drive anything.
