Master Airscrew MA1860C 18x6 Two-Blade Propeller Classic Series  [MA1860C]

18x6 Two-Blade RC Prop — Technical Summary

This Master Airscrew MA1860C Classic Series 18x6 propeller is supplied as an RC replacement part for fixed-wing model aircraft. The 18x6 sizing indicates diameter and pitch which influence expected thrust, RPM range, and the compromise between climb and top speed for a given motor and battery configuration.

The propeller is a conventional two-blade design for general sport and scale use. When fitting, inspect hub diameter and shaft clearance, use the correct locking method for your spinner assembly, and ensure the blade's rotation direction matches the motor installation.

During setup and tuning regard the propeller as a load on the propulsion system: swapping to an 18x6 will change current draw and motor loading depending on cell count and motor KV. Check with a wattmeter, balance the blade, and perform ground tests to keep vibrations and wear to a minimum.
