Engineered Spur Gear for RC Models

The Serpent 120021 is an 87-tooth, 48-pitch spur gear made for electric RC cars and trucks. Constructed from resilient nylon, it offers a balance of toughness and low mass to help preserve motor efficiency. The pattern of holes around the face allows easier access to motor mount bolts, making swaps and mesh checks quicker at the bench or track.

What Comes With the Serpent Spur Gear

Robust Nylon Build: Material chosen for impact resistance and consistent wear characteristics.
Service-Oriented Design: 12 small and 9 large access holes to simplify motor adjustments.
Easy Identification: Tooth count is clearly indicated on the gear for fast reference when changing ratios.
Broad Compatibility: Works with many electric RC kits and converted models.

Is the Serpent 120021 suitable for bashing and racing?

Yes, its nylon construction handles general bashing and club-level racing. For heavy-duty competition or extreme bashing, monitor wear and consider replacement intervals based on running conditions.

Can I use different pinion sizes with this spur?

The 48-pitch specification lets you pair the Serpent 120021 with standard 48P pinions. Choose pinion tooth counts to tune top speed versus acceleration for your motor and battery combo.

How should I check gear mesh after installation?

Set a normal mesh with a business card or plastic shim, then run the drivetrain by hand to feel for tight spots. Fine-tune motor position using the access holes to achieve even contact across the tooth face.
