Odd Q and my deciding factor on a kit as I've invested a ton in gearing. What pitch is the Serpent? What gearing does everyone recommend to start on a 13.5T, 17.5T, and 21.5T? I'm trying to figure out if I have the right gears.

Is the Spur and Motor easy to remove? I'd like to try and get two classes out of the car. I'm done having a car for each class.
