–About Motor Spec–

What is ” T ” ? 

“T” means “Turn”.  A lower turn value produces less torque but higher speed.  A higher turn value produces more torque but lower speed.

(less Torque/higher Speed) 50T<— 60T—70T—>100T (more Torque/lower Speed)
———————————————————————-
Tips: Off-Road Crawler Requires More Torque (use big final ratio)
         Off-Road Big Angle Crawler Requires Much More Torque (use bigger final ratio)
         On-Road Racer Car Requries High Speed (use small final ratio)

What is Final Ratio?
Final Ratio = (Spur Gear ÷ Motor gear) x 7.692 (this figure is only for Axial AX10 Crawler Car)
eg.   116T    ÷     18T      x     7.692   =    49.57
——————————————————————————–
Original Final Ratio : 33.46                                                                                                                 
*you can adjust the final ratio at your own discretion to control the speed and the torque. If you need high speed, use small final ratio; if you need more torque, use big final ratio.

A bigger final ratio means more torque and low speed while a smaller one reflects less torque and high speed. 

Caution:
If the final ratio is smaller than what the car requires, the motor may be overheated.
If the speed of the car does not accelerate, it may mean the final ratio is too small. You need to adjust the final ratio.
