Heat problems with Mambamax/stampede

[hyperasus]

Sounds like I better use a different motor. Too bad I have 4 of these lemon mamba motors. The mamba max speed controller owns......but WOW thier motors are worthless. I have 2 Lehner 1920 motors, 3 Lehner Basic XL, 1 Lehner Basic, 2 BK 10 turns, and + my mamba motors. Not a fricken one of them will stay under 150F on my pedes and rusties. Im about to just buy a Lehner 1950 for my pede and maybe it will be able to handle the load without overheating. Oh wait....I can't because the pede has to have the 1/8th shaft.

What about you guys. Are there any of you that have a brushless pede or rustler with max sized tires that doesnt overheat? I'm not talking about 10 or 15 minute runs then let it cool down. I'm talking about running down a 8000mah lipo pack full throtle in the dirt or sand. If so then will you please post your, speed controller, motor, and gearing.
