This thread is a bit old, but I'll update it anyhow. The emaxx is still running fine on the 2s2p's and the motors are holding up. The truck has taken a beating however.
your running two 2s2p 7.4 lipo cell packs? i have a feeling that those titans will burn out.
If you add spacers in between motors and bracket it will help a lot with cooling problems. Better then extra heatsinks... Will work only with motors with built-in fan, like Titans, but not with like Trinity mild/wild/pro.
