Problem With Spur and Pinion
 

Hi there... ;)

Im really need help, as im not good in fdr counting, for your info im using sakura zero with Turnigy Track 100a ESC and Orca RX2 10.5t (Sensored) motor, Now, after changing Spur to 83t and Pinion 26t my car has no top speed, Great on Tork but no top speed, and im really cant remember the original spur and pinion.., did spur and pinion conversion really give impact on car top speed..

Sorry... Im Newbie :blush:

spur/pinion * Internal drive ratio. You should be able to find the internal drive ratio in your manual, if not divide the teeth in the driven pulleys by the teeth on the pulley your spur is mounted to. Depending on who manufactured your motor you may be able to go to their website and get information on a suggested FDR for the motor you are using. And yes, gearing has an effect on top speed.

Changed from what?

Hi there,
formerly, it use 80t spur and 26t pinion at the front, and i've change it to 83t spur and 26t pinion....never touch rear, it still use stock Gear Ratio: 38t/20t
and im using IP Batteri 6200mah/70c...

Smaller SPUR- more top speed (hotter temp)
Smaller PINION- more Torque (cooler temp)
Bigger SPUR- More Torque (cooler temp)
Bigger PINION- More top speed (hotter temp)
