HQProp 7.5X3.7X3 Light Grey (2CW+2CCW)-Poly Carbonate

Meet the HQProp 7.5×3.7×3, a high-performance tri-blade propeller set engineered for larger FPV frames capable of handling >7″ props. Unlike standard two-blades, these 7.5″ tri-blades deliver significantly more static thrust and enhanced mid-throttle response, giving your quad the lift and control it needs for aggressive freestyle, cinematic moves, or agile cruising.

Crafted from tough polycarbonate, these props combine lightweight build (9.4 g each) with resilient durability—perfect for frames that experience repeated impacts or high-stress flight styles. The 3.7″ pitch offers a pragmatic balance between speed, lift, and efficiency, allowing you to squeeze more performance from your motors without sacrificing battery life.

🧾 Specs & Build Insights

Each prop is 7.5″ diameter, 3.7″ pitch, and a tri-blade in light grey PC. Weight is about 9.4 g per prop. The hub is 15 mm (≈6.8 mm thick) with a 5 mm shaft hole, making it a drop-in match for most 7″+ FPV setups.

⚙️ Precision Pairing & Setup

The set includes 2× CW and 2× CCW blades. Clear direction markings simplify installation; just align, torque evenly, and fly. Proper pairing preserves thrust balance, reduces vibration, and keeps footage stable.

🛩️ Flight Dynamics & Efficiency

A larger diameter plus tri-blade geometry yields strong lift, smooth tracking, and predictable transitions. Expect better hover efficiency, snappier direction changes, and stable lines, with energy use tuned for practical flight times.

🎯 Ideal For

• Freestyle pilots needing steady thrust on 7″ frames

• Cine flyers chasing smooth, low-noise footage

• Endurance/long-range builds balancing lift and draw

• Practice sessions where polycarbonate durability matters
