HQProp 4X3X3V2 Polycarbonate Propeller (2CW+2CCW)

The HQProp 4X3X3V2 is a tri-blade 4-inch propeller for 4-inch freestyle, light long-range and cinewhoop builds, sold as a complete two-clockwise/two-counter-clockwise set ready to bolt straight onto the build.

Key features

• 4-inch diameter with a 3-inch pitch for smooth, linear throttle response through the whole stick range.
• A third blade adds bite over a two-blade prop of the same size, trading a little top speed for sharper punch-outs and tighter cornering.
• Standard 5mm (M5) centre bore fits most 15xx to 22xx FPV motors without an adapter.
• Tough polycarbonate moulding resists shattering on minor crashes and hard landings, holding its shape better than cheaper PC blends.
• Each blade set weighs just 2.2g, keeping the build agile without sacrificing thrust.
