Hot motor OUCH!
 

So i had been running my 4s and 5s lipo pack on my Mamba Monster 2200kv combo, in my 8t 1.0 race roller kit. im using 48t metal spur and 16t pin. I think my motor is getting way hot, so hot that my spit just sizzles away. ESC/Batteries are nice an warm if even that. Thoughts? I have a 15t pin i can use, i want the engine cool and fast, can i change some settings on my ESC to correct this? Or do i need to change pin or spur?

If you're boiling spit away chances are you've gone well over 200F and most likely a point of no return. With those kinda temps I bet the protective coating on your windings is bad or gone in some places creating a short circuit. Could also be that you damaged your windings with screws that were too long when you mounted the motor. Not saying this is the case, it could just be way over geared.

Get a temp gauge, only real way to tell how hot it's getting.

Yah, because technically it shouldn't take much to evaporate a water based liquid away... ~160F I'm sure. Get a temp gun just to be sure.

TEMP GUN, Lower gearing, Higher Punch control,lower motor timing. ALL Nessecities for cooling running.

you say that the engine may be past the point of no return? It has ran strong and fine. I have a temp gun which is not very accurate. Ill try the things u guys suggest and see where i am at. but the point of no return comment. wouldnt i be able to see some signs of damage? Engine not running right, acting funny? becuase its running like a scared ape. can i look inside the engine and see damage? now you guys have me worried. i dont want to have to buy a new engine.

A motor that has been overheated to the point of partially demagnetizing the rotor will get hot with equal or less performance as it had. Not only is the motor getting hotter (lost efficiency), but it is harder on the ESC and battery as well.

is there a way to tell by looking at it?

Not really. The anodizing on the motor case sometimes can have fine "cracks" if it got too hot, but doesn't necessarily mean it did get too hot. Even a little loss in magnetic strength can result in a substantial loss of performance and increased heat.

Has your runtime decreased lately? If a rotor got partially demagged, you probably have to apply more throttle to retain the same performance, and this should show up as reduced runtime.

What gearing are you using? If you are running on asphalt doing nothing but high speed runs with little stop-and-go, the motor could just be would out and need a little more gearing. If you are doing lots of stop and go (like racing or general bashing), gear down a couple of teeth.

its brand new, i have ran 2 packs thru it. 4s1p 5000mAh and a 5s1p 4900mAh and that is it. the first pack it didnt really get to hot. the 5 cell pack is when it started heating up. I just want to know if i need to buy a new motor. I am running mamba monster 2200kv combo 48t spur, 16t pin. i want to stay around 40ish if i can, even 35 i guess. Its for my 8ight-t 1.0 race roller. Its probaly had about an hour of run time on it total, and its not like it was running non stop, i would run for a few laps, then stop for a bit to kool down. One thing for sure tho is that the engine doesnt cool off real fast. New engine or not? If so which engine would be decent? Its almost like the 2200kv motor is to much for the Truggy. Thoughts, Help!

If it's brand new, I'd try gearing down a tooth or two first. If you do a lot of stop-and-go on a tight track, you probably need more torque and aren't hitting top speed very often anyway.

what do you think about the engine being damaged tho? Chance everything is ok?

Run it gently for a while. If it still gets hot, then something happened to it. If it's cool, gear down and run it normally.

On the gearing down part, should i try the 15t pin or go lower? what settings should i change in the Mamba Monster to improve cooling? ESC us staying cool so are the batteries. Any info our thoughts are appreciated.

15t pinion on 5s is crazy speed for sure, i run a 13t for 4 or 5s with a 1y, shoot 13t on 4s is fast enough!
