gearing

[RC-Monster Mike]

Make sure your driving can keep up! 18 cells with an 18/54 pinion/spur combo will be pretty insane! Insane speed and torque! I would definately recommend a fan for the controller at this point. This setup will easily push your truck into the 50mph range. Please bash with a lower gear ratio. For a speed run, you can push the envelope a little with the gearing, but for playing around, it's best to keep the gearing towards the mildly insane side (as opposed to the "needs to be committed to a nut house immediately" insane side!):)
Gotta get some video before you break the sound barrier!
