16x12 120 Pattern Two-Blade Prop APC AP1612 Propeller for Electric RC Aircraft  [AP1612]

Product summary and purpose

The APC AP1612 16x12 propeller is an aftermarket two-blade prop designed for hobby RC aircraft. The 120 pattern denotes the blade profile while the 16x12 marking indicates diameter and pitch, helping pilots choose props for thrust versus efficiency trade-offs.

Fit this prop as a swap for thrust tuning, bench testing, or comparing blade geometries on electric model aircraft. It is supplied as a single prop item compatible with standard mounting arrangements; confirm your hub size and mounting method on the airframe before installing.

Quick installation steps: follow your motor and spinner maker instructions to remove the existing prop, inspect the new prop for damage, orient the AP1612 to the correct rotation, and secure the nut or washer to the motor manufacturer's recommended torque. After fitting, perform a low-throttle static spin to check clearance and retention.

Balancing and tuning tips: statically balance the blades on a prop balancer prior to the first flight to reduce vibration that can affect airframe and electronics. Minor weight tweaks at the tip or hub can refine RPM smoothness. During testing, monitor motor temperature and ESC response across throttle ranges to determine the best prop/motor/ESC pairing.

Care and inspection: check the prop each flight for nicks, cracks, or delamination and replace immediately if damaged. Keep matched sets of props for consistent test comparisons.
