Master Airscrew MA1860C Classic 18x6 RC Propeller  [MA1860C]

Two-Blade 18x6 Prop — Setup Notes

The Master Airscrew MA1860C Classic Series 18x6 propeller is intended as a replacement blade for fixed-wing RC models. The 18x6 marking denotes diameter and pitch which helps predict thrust, RPM band, and the general tradeoff between climb and top speed for your setup.

This two-blade prop suits general sport and scale model use. When fitting a new prop, check hub fitment and shaft clearance, secure the prop with the correct fastening method for your spinner, and confirm the rotation matches the motor to avoid counter-rotation issues.

Consider the prop as part of the overall propulsion system: different motors, cell counts, and voltages will change the electrical load. Verify current draw with a wattmeter, balance the prop before flight, and perform static checks to reduce vibration and prolong hardware life.
