I have a emaxx with mamba monster esc and 1800kv mamba motor, Im using 20/64 gearing but after 6-8 min the motor is hot, do I need to change gearing?

Whats hot? Hot to the touch? Water boils at 212 degrees, can you keep your hand in boiling water for more then a few seconds before you have 3rd degree burns?

185-200 degrees is the "hot zone" for BL motors. They can and will still be just fine if you get one to 200 degrees but most of the time neodymium magnets start to demagnitize at that temp.

Check your temps and gear it accordingly. Start back at a 15T and go up.

Hot to touch, U have to remove hand from motor maybe after 2-3 secs.

You have to go out and pick up a temp gun/guage for a B/L or brushed motor. Don't let your finger be a judge. 160-170 degrees feels screaming hot but your motor is perfectly fine.


Just something to keep in the back of your mind.

Once you damage a B/L motor by overheating it, it becomes less efficient meaning it will still get the speeds you once got but it takes a lot more MAH and it will heat up a lot faster. If you gear it down and it still heats up 180+ (even with stock gearing) in the same amount of time you already said, chances are it's probably shot assuming you are using a temp gauge with accurate readings.
