It depends on your motor and the track. In the 1/8 4WD buggy class, racers gear by final drive ratio: 1800–2300 kV near 10.06. On the Typhon TLR-Tuned's stock 50T spur that is about 16T for 1800–2300 kV. Tight tracks gear down, open tracks gear up. For a starting pinion matched to your motor, use the So Dialed Pinion Recommender with the Typhon TLR-Tuned selected.
What is the internal ratio (transmission ratio) of the ARRMA Typhon TLR-Tuned?
The Typhon TLR-Tuned has an internal ratio of 3.3:1. Final drive ratio = spur ÷ pinion × 3.3. With the stock 50T spur, a 12T pinion gives an FDR of 13.75 and a 19T gives 8.68.
How many teeth is the stock spur gear on the ARRMA Typhon TLR-Tuned?
50 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.
