Arrma BLX 4074 4-Pole 6S Brushless Motor (2050kV)
THIS THING IS AMAZING!! I’ve had it running in a e-maxx (don’t hurt me) for about 2 years now, and it still works amazingly. With correct gearing it will easily hit 60mph! I’m not sure how you could kill this motor, the whole thing is aluminum, it’s never stopped working, shorted, or done anything bad. I’ve jumped it 20+ feet in the air, fully submerged it, landed the car upside down on it, and it still is alive. I’m not sure how it is but it still is alive!! If you’re looking for a nice, high power brushless motor, this is it!!!

Replacement motor after almost 2yrs. On the first one. I would have to say pretty good motor, I ran more than 350 sets of batteries ( 2-3s 5200 mah) at the track. It was time for a new one, even though the one still runs good, a little sloppy.

Performance equals original motor, the old motor pinion gear set screw socket rounded off and was drilled out. Perhaps the wrong loctite contributed to the failure.

It's a motor the truck calls for and it works just like the factory motor.

great motor for performance , but it doe,snt last long. This is my third motor for the kraton ! What suck,s about arma is there is no after market suport !!! A Castle motor or a Teken motor would out last the arma motor !! When I take apart the arma motor I see the armature is wraped in some cheap ass fiber paper that does,nt stand up to dirt or heat. BOTTOM LINE IS THE ARMA MOTOR IS A PIECE OF SHIT!
