Brushed Modified Motor Maintenance
So one for you guys racing with brushed setups.
Once you’ve rebuilt a motor (which may include a com skim, new brushes etc) how are you timing them if you don’t have a dyno?

Tbh i just left it at the manufacturers settings and did well with that, yes when you dyno you make it more efficient and sometime more torquey but as lipos are now on the scene with ratings for more torque the stanard setup should be powerful enough.

I always used to time motor to 3.5 amps at no load full voltage. I’m pretty sure this wasn’t the correct approach but like you it seemed to work well. Back then I had a Shinwa motor dresser, unfortunately not now.

I normally mark the can & end bell before taking motors apart for a skim and then just line it back up when rebuilding.

As default, I would always mark the can from the original settings it came with. I never really used to play around with the timing of motors who had a reputation of churning out good motors and I bought as new.
Only time I played with the timing is when they were cheap motors - good enough for club racing, which were new But weren't run through a professional dyno. Also when I buy a used one from one of the sponsored driver who had the motor for 2/3 meetings from new, never been skimmed. I would connect it to a pack of batteries and adjust the timing for max rpm by ear/listening to the revs and back off 2 degrees. I used to do this a lot for old motors which didn't have great magnets due to their use & age, I figured, you weren't going to get punch or torque but you could get better top end (to a degree).
