XRAY - Model racing cars

Hi All,

I have nearly finished building my XT4 '15 and need a pinion gear. I have an Orca TX 17.5T motor and I would like to run something fairly conservative (slow) in order not to stress the motor and to learn to drive better. I would be grateful if people could advise which pinion gear would be suitable.

Thanks, Al

With an 84t spurgear,34 or 35 is a good starting point.

Thanks for this. I have ordered a 30 to 36 T set.

Should be able to find something there that works.

Cheers, Al
