HQProp 7×3.7×3 Propeller — Grey Polycarbonate (2CW+2CCW)

The HQProp 7×3.7×3 is a 7-inch tri-blade propeller tailored for mid-to-long-range FPV cruisers and cinematic rigs. Moulded from polycarbonate, this grey prop provides high thrust and stable authority at lower RPMs. The shallow 3.7-inch pitch is specifically engineered to manage amp draw, allowing larger 7-inch builds to carry heavy Li-Ion battery packs and action cameras while maintaining efficient cruising speeds and extended flight times.

Key features

• 7-inch diameter paired with a shallow 3.7-inch pitch to minimise amp draw during steady long-range cruising.
• Tri-blade configuration provides stronger flight authority and cornering grip for heavier cinematic setups.
• Constructed from durable polycarbonate to resist bending and shattering on rough terrain landings.
• Standard 5mm centre hole fits common M5 threaded motor shafts on 28xx and larger stators.
