Help with choosing parts for a first robot, please.

Cool thanks, will try that out later on.

Probably easier if I explain this with a picture:

I thought that if I move the stick to where the red mark is the robot is supposed to spin? Right now the robot still goes forward in this position, and only moving the stick horizontally right and left makes it spin on the spot quite slowly. Unless it's meant to be like that, feel free to correct me. :P
