    How about the 5.5? Should be a little faster than the stock VXL but still have low temps and decent run time.

    Talked to Novak last night about a 5.5 or 4.5 From what i was told, a 5.5 is great and ppl go to a 4.5 if a little more speed is needed for a larger track.

    Or you can gear up the 5.5 higher if you need more speed. 20/50 gearing should put you around 45mph on 2s. Yes, the 4.5 can get you faster on 2s, but I would rather start using higher voltage (3s lipo) rather than higher gearing or higher Kv to go any faster than that. Using higher voltage and lower gearing allows the same speeds to be achieved with lower amperage, and therefore lower temps.
