Got a couple of Checkpoint 19Ts. Skimmed the comms tonight and cleaned the brushes. Both smoke when I run them at 5v to dyno them. Looks to be coming from the brushes. What causes that? Did I do something wrong?

What dyno did you use to test the motors?

If it was a Fantom, they can hit the motor with a lot of amps at start up and if the brushes are not seated or the timing is off that could have caused the problem.

I guess I should have said "dyno" or motor checker. It is a Integy. Tried it with my ICE and it did the same thing.

I have had a somewhat similar smoking issue, I had a silver can that smoked if you put in more than 2v. usually a SC motor draws about 1amp on 2v, during run-in, but this one would draw about 4 amps on 1v, 8 amps on 2v and my charger (on run-in mode) would cut power to the motor when it drew more than 10amps. the motor got replaced under warranty, I think the problem was that the bushes (you would have bearings) were out of alignment, and being a SC, they are sealed and inaccessable. I'd check the bearing are correctly seated, and try again...

hope this helps
