Overview
The line of Tekno RC M5 Pinion Gears stands out from the rest. These are the ultimate pinions for 1/8 electric and any other MOD1 pinion application, and with the range running from 11t all the way to 30t you are sure to find the right gear ratio.
This 13 tooth gear is a common starting point for 1/8 electric gearing. It uses a 5mm bore and an M5 set screw, which is larger than the set screw hardware found on many competing pinions and so has more thread biting into the motor shaft.
Key Features
- 13 tooth count with a MOD1 tooth profile
- 5mm bore fits standard 1/8 scale brushless motor shafts
- Oversized M5 set screw
- Part of a range covering 11t through 30t
- Suited to 1/8 electric and any other MOD1 pinion application
Performance Benefits
- Useful baseline ratio to gear up or down from as track conditions change
- Larger M5 set screw grips the motor shaft more securely than smaller hardware
- Accurate MOD1 tooth form meshes smoothly and quietly with the spur
- Changing the pinion is the fastest way to tune power delivery and motor temperature
Usage Notes
- Requires a motor with a 5mm output shaft
- Must be paired with a MOD1 spur gear
- Set gear mesh with a small amount of backlash, not tooth-to-tooth tight
- Use the correct hex driver on the M5 set screw and re-check tightness after the first run
