This is Novak's 5mm Mod 1 Steel Pinion Gear 3-Pack (15T/16T/17T) (#5122). These hardened gears are available in packs of three gears, allowing drivers to experiment with gear ratios. In addition to the added flexibility, the three-gear packs save money by giving drivers the ablility to purchase a pack of gears, instead of buying individually.
Novak's 5mm Mod 1 Steel Pinion Gear: 17T is, overall, shorter in length to easily fit into all popular brushless 1/8-scale vehicles. These shorter gears allow uses to take advantage of the lower Kv generated by the HV Sintered Tuning Rotor with 5mm Shaft – 14mm. Additionally, the vehicle’s gearing must be decreased for an overall lower gear ratio.
The remaining Mod 1 Pinion Gears included in the 3-pack -- 15T and 16T -- are Novak's original-gear style. These slightly longer gears are also compatible with Novak's HV Sintered Tuning Rotor with 5mm Shaft – 14mm.
All of Novak’s Mod 1 gears include a set screw and have the gear size marked for easy identification.
