Precision Pinion: Arrowmax AM-308017 17T

The Arrowmax AM-308017 is a precision 17-tooth pinion in 0.8M pitch, produced from 7075 aluminium to deliver steady drivetrain response. It suits builders wanting accurate tooth engagement and reduced rotating mass.

Lightweight Strength for Better Response

7075 aluminium provides a high strength-to-weight ratio, helping reduce inertia while maintaining tooth durability. The hard anodised coat helps shield the contact surfaces from premature wear.

Simple Fitment for 0.8M Setups

This pinion is made to pair with standard 0.8M spurs and common motor shafts, enabling straightforward installation and dependable running across typical RC environments.

How do I check if 17T is the right size?

Compare the tooth count with your current pinion and desired gear ratio. A 17T will give a particular top speed and acceleration balance versus larger or smaller pinions.

Can I replace a worn steel pinion with this aluminium one?

Yes, provided the pitch and shaft fit match. Aluminium is lighter and often smoother but inspect for wear more regularly than with hardened steel under heavy loads.

What signs indicate the pinion needs replacing?

Look for rounding of tooth faces, inconsistent mesh noise, or slipping under load. Any visible chips or severe wear means replacement is advisable to protect the spur.

Do I need to retune mesh after the first runs?

Yes. New pinions often seat after a few minutes of running, so recheck mesh and fastener torque after initial use to ensure correct engagement and prevent premature wear.
