In this category you'll find props intended for piston engine use. Fuel type props have heavier hubs able to better able to sustain the power impulses of a piston engine.
APC propellers are a mainstay on club flying lines, and this sport series covers a wide span of diameters and pitches for glow and electric power. With a large number of sizes on offer, the category makes it easier to fine-tune how a model pulls and climbs.
Small and Free Flight Sizes
At the small end, props such as the 4.2x2 and the 4.2x4 free flight prop suit tiny models and light power systems where a compact diameter is needed.
Sport and Larger Diameters
Moving up, sizes like the 10x10 electric prop and the 14x10, 14x13N, and 16x15 sport props cover bigger sport airplanes and higher power setups. The wide range of pitch options lets you trade top speed for climb to match your flying style. A higher pitch number moves more air per turn and favors speed, while a lower pitch of the same diameter tends to unload the engine and pull harder off the line. Having several close sizes in the box makes it easy to experiment and settle on the prop that suits a given model and field.
Use the diameter and pitch on each prop to match one to your power system below.
