I am having problems with my emaxx brushless motor.
I have been running cool up until last night when it stalled and quit moving. I would hold the trigger and you can hear the current buzz but no movement.
I saw some smoke so I disconnected and later took the motor apart to find there is nothing visibly wrong inside so I put it back together and it runs! Now though it gets hot very fast and there seems to be less resistance when you roll the wheels by hand. But when I am running about 40mph and let off it almost locks up (great cornering!) I don't know if I can rebuild this motor or if there's a simple fix or troubleshoot method.
I just ran it half way and had to stop before it cooked the motor.

I have emaxx with 150a esc 2200kv flux motor running 4 cell lipo. 21/68 gearing, badlands and all aluminum.

I must have ran it about 40x with no heat issues until the day it stopped and smoked now it runs hot and dives when I releases the trigger.
Thank you in advance for your input and happy new year all!

Are you sure there's nothing binding in the drive train? Sounds like somethings binding, unless you dialed up the drag brake, it shouldn't come to a stop like that when you let up on the throttle.

No I checked the drag every value is the same and I just got done re-rebuilding it and trying it just in my hand with no pinion and it smoked at high rev.
I think one of the wires inside must have fried. Or is loose? I don't think the esc would be the cause maybe giving off too much juice? I'm going to re wire it and see

Holding it and reving it causes smoke under no load...

I think she's fried so I ordered a monster mamba 2200 problem solved lol

You know you can send the dead one back to Castle and get a new one for $80 even if its out of warranty?


BTW, reving a brushless motor with no load to high revs is generally bad for the motor....

I don't think they would take a flux motor and thanks for the heads up.
