HQProp 7X5.5X3 Grey Propellers (2CW+2CCW) - Polycarbonate

The HQProp 7X5.5X3 is an aggressive 7-inch tri-blade propeller engineered for high-speed cinematic tracking, mountain surfing, and heavy-lift mid-range builds. With a steep 5.5-inch pitch and rigid polycarbonate construction, it delivers exceptional thrust and immediate throttle punch for 7-inch quads where maximum top-end speed and carrying capacity are required over flight efficiency.

Key features

• Steep 5.5-inch pitch generates high thrust and top-end speed for heavy 7-inch macro quads and long-range cruisers.
• Stiff polycarbonate construction maintains blade profile and airfoil shape under high aerodynamic loads without flexing.
• Standard 5mm center bore mounts directly to standard M5 threaded motor shafts without the need for adapter rings.
• Factory balanced to minimize high-frequency mechanical vibrations and jello on HD action camera footage.

This propeller pairs best with larger stator motors ranging from 2806.5 to 3110 on 6S LiPo power systems. Because the aggressive 5.5-inch pitch pulls significant amp draw during punch-outs, ensure your electronic speed controller (ESC) is rated for at least 50A to 60A continuous current.
