Hi,
I'm new to radio controlled cars and was wondering if there is anybody who can help me with a problem I am having in setting up my new car.
I have recently purchased a Cat SX2 pro rolling chassis and then an ESC ( speed passion cirtex stock club race) and 10.5 turn brushless motor ( HPI racing flux pro competition ) to put in it.
 
My problem is that I am unsure about how to set up the gearing.
 
It needs a new spur gear but I don't know what one to purchase as they range from 72-83 teeth. Also I don't know what size pinion I need on the motor.
 
I would be grateful if anyone out there could help me or point me in the right direction to find out the information that I need.
 
Many Thanks, Ross.

With my old SX2 i ran a 5.5 and had it geared 22/80. With a 10.5 though i'd think you would need to be in the 28-30 tooth range.
