ProTek RC Steel Mod 1 Pinion Gear (5mm Bore) (15T)

I got 14t, 15t, and 16t. They're nicely made pinion gears, but unfortunately they are not mod 1. Module system gears are easy to check: outside diameter equals (number of teeth + 2) times the module. The ProTek mod1 14t measured 17.00mm (not 16mm) and the 15t measured 17.93mm (not 17mm). This explains why the other reviewer observed poor fit with the Losi.

For the sake of comparison, I have a few other actual mod 1 gears sitting here. The Tekno 16t measures 17.96mm (correct), Robinson's 16t is 18.00mm (also correct), Tekno 44t spur is 45.98mm, Arrma 24t is 26.00mm.

In summary, these gears appear to be module 1.something. So if you need a mod 1 gear, don't buy this.

Do not fit Mugen MBX7 ECO in the shape of the teeth, the module is not m1. :(

These work perfect for 1/8, strong and reliable.

great quality, i´m using this pinion on my serpent 2023 GTE car with the hobbywing xerun XR8 pro G3 ESC and xerun 4268 2400Kv motor and it works perfect for long fast track.

excelente muy bien llego como lo solicite en perfectas condiciones

High-quality, high-strength, low-cost..I highly recommend it.

High quality and low price...Good
I bought more than five

I'm not one to write reviews. However, just spent 20 minutes in my Traxxas Maxx. I'm running Pro Line 3.8 Trenchers with a Metal 50t Xmax Spur! It resolved my constant cogging nightmare!! And i've had a Tekno Pinion (20T) matched with a 50T Hot Racing Spur. The TEKNO cut through my Hot Racing Spur like a knife to butter. In the end its all about how you drive. When I let me son drive he destroys all gears because he loves to rev the crap out of the motor and wheelie all day. Anyways GL!

Should have a bigger grub screw so you can put more torque on it.

My order arrives as expected. thanks for the fast shipping.
