The sidewinder gears are called Spur gears.. a crown gear is for inline use....
With the slot-it gears they are all the same dia. but for a short track you will want a higher gearing... say 10/38 or so.... that is a 10 tooth pinion with a 38 tooth spur gear...... That will give you good acceleration.... for longer track you want to gear lower.. like a 10/34 or so.......
The tooth count of the pinion and spur give you your gear ratio.. 10/38 is 3.8 : 1
good for short track..... You will find all the slot-it gears to be smooth running....
