i'm interessted in a Ken Block Gymkhana Fiesta car. I'm new to all this stuff, so i'm not sure if this is all the right direction to start with?!
Further i'm from germany, so if i order the car, i want to have the "Upgrade" with it. Means the 1400mah 11.1v 3-Cell 25C LiPO Battery + Wire harness, parallel battery connection and the optional pinion gear, to get the ~ 50mph.

My first question: What optional pinion gear do i need (link from traxxas.com)? Am i ready with that to have a good start with the car?
Second one: Is this all a good idea to start with ? Because i order from germany, i need a good package to have some fun with the car without taking a second or third order.

thanks so far!
