Yeah, I know, who uses these anymore ?

Anyhow, I had some of these BNIP from a few years ago and figured i should put one into use in my Wife's RC10T3...

It's an Orion Core Stock:


Anyhow.
After a lap or 2 around the track its started to die, loosing power and then just wouldn't move.

Had a quick visual inspection and couldnt see anything strange, no burnt brushes or anything.
However, I did notice that after pulling the brush away from the comm and letting it reseat it would start to move again.

Is there some kind of run in procedure for a motor like this ?
Never had problems like this before with a new motor...

Anyone got any ideas ?

I take 2 AA batteries and run them in series directly to the motor until they are dead. This runs the motor slowly breaking the brushes in. I just use tape to hold the batteries together. When they are dead I clean out the motor with motor cleaner and then re-oil the bearings.

thanks for the pointers Fred,

Do you think this is likly to be a run in issue, or somehting more serious ?

You might check your LHS. Get some stronger brush springs, you got a brush hung up. A commen problem with brushed motors running in offroad.

If the motor has been sitting around for a long time the springs may have weakend and you may need to get new brush springs or take them off and bend them a little bit so they press down on the brush harder.
As above a common problem with older brushed motors.

thanks for the tips guys,
I'll try some new brish springs.
