Heat problems with Mambamax/stampede

I've had the same problem with my rustler... mailed the motor back yesterday. even little 5 min runs would heat it up...

I killed my first mamba motor letting it get up over 200F (more like 250F actually LOL). Anyone else running close to the same setup? Is the mamba max motor simply to whimpy for the pede/oversized wheels?
