**pulls funny face**
There used to be an awesome thread where hundreds of different setups were posted (vehicles/voltage/motor type & kv/gearing etc etc), and 99.9% used the 4-6s setups that we've been suggesting; I doubt that many people would be using setups that were wrong. Even Castle themselves suggest 6s lipo with the MMM&2200kv system, and gearig for a reasonable 40-50mph. All I can suggest is try it for yourself before buying a new motor and running it on a dodgy setup (again)
