I‘m using a brushed motor and as part of maintenance, I routinely blow debris out of the car and motor with compressed air. Once cleaned, I add a drop of LaBelle 107 oil (primarily designed for model trains) to the bearings and comm. Usually this works fine.
The other day, the car started smelling like it was burning. It was sluggish at first, then took off. The burning stench was bad. It smelled like fried electronics but the car worked fine the rest of the day.
A few bashings later, I cleaned up and lubed the car and motor, put the batteries in and decided to hold the car up and spin the tires and turn the wheels to make sure everything works after reassembly. That’s when I noticed the inside of the motor was all but on fire when I applied the throttle! Not just sparking and arcing, but flaming. It only did this for a few seconds. Pretty sure it was the LaBelle 107 oil on the comm and brushes burning off. Wow - the stuff is supposed to be safe for brushes and states on the label it is to be applied directly to the comm and brushes.
I think the problem was me applying full throttle to the motor right after applying the oil to the brushes. If I’d run it 1/4 throttle for 30 secs or so this wouldn’t have happened.
So - should I skip lubing the comm and brushes? Use a different product to do so?
Did I damage the receiver or ESC when that motor was flaming out? (I believe it was basically shorting out for a few seconds.)
I am new to the hobby, BTW….thanks!
