I'm running the novak 5.5. I love it but I would like to be able to go faster on road. Thinking of talking my girlfriend into getting me a MMMv3 for x-mas then getting a tekno neu once they're in stock. I have a 2 SPC 2s2p 8000mah lipos. If I do decide to get a MMM I'll get 2 SPC 3s 8000mah lipo. I'll defenatly keep the novak as a back up. Just throwing this out there. I want to get more torque. Will there be a difference on 4s. Plus my cousin is getting a medusa and an mm for his rusty so I want my Erevo to keep up a little on-road.
