With the other replies here I am led to believe it is more than likely my assembly of the diff that led to the "melting". My V1Pro came with all of the V2 upgrades, including the steel outdrives. Currently the car is sitting in a corner waiting for me to rebuild the diff again, lol. I didnt run it the second time, after I put it back together and did a test roll, the axles are clicking, so I have to try again...I think I backwardized it.
I didn't run any extra cooling for the Max 5700, and during the run the motor did get quite hot, but I believe that is due to the cheap-o LiPo I was running not being up to the task of supplying the MMax. The SB PRO motor heatsink does look awful pretty with the mamba color scheme, too...
