Is that strange smell from the motor or the gearbox Grease

Every motor smells a little bit different when it burns up. 775s smell kind of burnt citrus-y. BAGs have this foul yogurt smell that’s really unpleasant. Some just smell like oil / spray paint smell / etc. It depends on precisely what is melting or burning in there. In any case, if you smell anything like this, I would take the motor off of a competition robot. On a practice robot that’s your call, since the risk is lower, but you could end up with drastically different performance.

And then there’s the smell of a smoky Redline. Clears the room in no time. Can’t say it smells like anything other than acrid.
