I would just keep going, as long as the smoke stops after a bit, all motors still retain the smell, but if the motor runs without any reduction in speed, keep using it, was it constantly spewing smoke?

I wouldn't say exactly that it was "spewing" smoke, but it wasn't like just a little bit of smoke came out and then it stopped. There was a fairly constant stream of a fairly small amount of smoke that lasted for two or three seconds until we noticed and turned it off.

Well, if that ever happens again, keep it running, and see if it stops, chances are you didn't smoke the motor! And if you need fast delivery banebots does send their smaller items VERY fast! Which is a surprise knowing their record!

You can also cut vents onto the mounting plate of the motor improve airflow from the front of the motor. You can do a quick search for people who have done the same on CD.

Have you tried a pinion puller like this one? (credit to TheFro, I didn't know these types of pullers existed until recently)

I don't think we have the exact pinion you need any details on it? I can double-check.

James, the real credit goes to google, all I did was google 'RC pinion puller' and found those guys.

As far as getting pinions faster, do you know the specs of the gear inside of the CIMulator? IIRC, they're 24DP, but I'm not 100% positive. If they are, you could order pinion stock from somewhere like SDP-SI or McMaster and make your own, or if you're really lucky, McMaster might sell the correct pinion already.

Yes, they are 24dp, but banebots never mentions the pressure angle and we aren't sure how to measure it.
