FYI: Time to come out of the dark ages. Next, you'll be saying you broke in your first nitro!
lol no i have done that enough times to convert my nitro to electric and sell everything that makes a nitro truck nitro. i have just run uncut coms on my brushed motors for 4 years or so and finally could see that some of them were just tearing up brushes left and right. i have had a lath but just never used it.
I got out my lathe and brushed motors last week, to put some old school stuff in my old JRX Pro. I didn't actually cut a comm, but grabbed a trinity 14x2 armature and a reedy endbell... to rebuild my Losi "Jr's Choice" motor. :) It's actually nice to mess with that stuff again, brings back some good memories of racing etc back in the day.
