the reason we break motors in under water is to increase the contact patch of the brushes on the stator, the motor being faster isn't true the motor is just running more efficient than it could with out the brushes broken in. always use distilled water as tap can have too large of particulates.
You can really see the graphite from the brushes in the water after you ran the motor for a bit. I have never taken the time to do this but I can tell it helps from your experiment. Nice work. 👍
I don't do any run in for stock silver can motor. I only did it for some of these 12T 550 motor that I got from RTR. They are great motor and sweet spot for any Tamiya build, hence looking after them and keep them for my next Tamiya build👍🏼. Thanks for watching, much appreciated🙏🏼
