Linc, I love to bash with larger type tires like Big Joes. So gearing will be on the lower side, I'll have to experiment. The wind is 1Y (1577 kv). Like to keep the RPM's high for stunts. Most likely I'll end up going back to a 1515 but it's fun to try different things.
Here is the Integy link: http://www3.towerhobbies.com/cgi-bin...?&I=LXWSY0&P=7
Thanks for the link. I have the std integy hubs on the x right now, and will see how they do... I may have to pick up a set of those hubs, they do look stronger...
Ran a few packs through it this weekend. I used two Neu 4S 4100 30C packs. A tight fit in the boxes, but they made it. The torque was incredible. What was really surprising was how cool everything stayed. After a full pack the MGM was warm, not hot, to the touch. The MGM also exhibited none of its previous quirks with braking or reverse. It ran smooth and solid. It all just proves to me that higher voltage setups are the way to go.
