RC Master Class 7: Propeller Aerodynamics & Thrust Efficiency

Propellers are the most critical link between your RC aircraft’s power system and its ability to generate usable thrust. Selecting the right prop isn’t just about diameter and pitch; it’s about understanding aerodynamic efficiency, motor load, thrust curves, vibration dynamics, and flight profiles. Advanced pilots know that dialing in the right prop can unlock performance, extend flight time, and prevent damaging current spikes in the powertrain. 1. Understanding Propeller Fundamentals Propellers function as rotating wings,...
