HQProp Ethix K2 Bubble Gum 6×4×2 Propeller

The HQProp Ethix K2 Bubble Gum is a 6-inch bi-blade propeller engineered for efficient long-range cruising and light freestyle. Developed in collaboration with the Ethix team, it combines a shallow 4-inch pitch with a two-blade profile to maximise flight time without sacrificing throttle response on larger FPV setups.

Key features

• Bi-blade profile reduces amp draw for extended flight times on mid-to-long range builds.
• Smooth 4-inch pitch delivers a predictable throttle curve with a distinct freestyle feel.
• Polycarbonate construction maintains blade stiffness across the RPM range.
• High-visibility "Bubble Gum" pink colour aids in orientation and post-crash recovery.

Specifications

• Diameter: 6"
• Pitch: 4"
• Blades: 2
• Mounting shaft: 5mm
• Material: Polycarbonate

This propeller mounts on standard M5 threaded motor shafts and is best paired with lower KV motors on 6-inch endurance frames or lightweight cruisers where smooth control takes priority over top-end speed.

Material: Polycarbonate.
