TA02 / DF01 Gear Ratio for 19t Brushless Motor ?

[TAZ-NZ]

What gear ratio should I be running in my TA02 chassis with 19T brushless motor ?

I've got the stock 74T spur gear and the Skyline Speed Tuned Gear Set with the 66T & 69T Spur gears to work with.

I need a recommandation on the ratio I should run, so I know what size pinon to buy, I plan on running a Robinson Racing Steel Pinon, I already have an aluminum motor mount.

The other catch is I'm running RC Boyz tires & wheels, they are larger in diameter than your stock touring car wheels, but also smaller in diameter that the DF01 buggy wheels.

I'd be very grateful for any input on this.

Well the safe answer is probably a 21 tooth pinion, as it spansboth the 74T and the 69T spur gears and falls roughly in the right motor power region for your 19turn.

Try the 21/69 first and check the esc and motor temps - if needbe you can swap to the 74T spur to lower temps.
