HQProp Multi-Rotor Pusher 12x4.5R 2CW Propeller

The HQProp Multi-Rotor Pusher 12x4.5R is a two-blade, clockwise pusher propeller in carbon-fibre composite for large multirotor and heavy-lift frames. As with any pusher prop, it is designed to run behind its motor, so the pitch and rotation are set up for that reversed airflow rather than a standard tractor position.

Key features

• 12-inch diameter and 4.5-inch pitch suit large multirotor powertrains with sufficient propeller clearance.
• Two-blade clockwise pusher geometry for installations where the propeller sits in a pusher rather than a standard tractor position.
• Carbon-fibre composite construction gives the stiffness needed to hold its shape at this size and pitch under load.
• Ships with shaft adaptor rings (6/5/4/3mm) so the propeller fits several common motor shaft sizes without a separate hub.

Specifications

• Diameter: 12 in
• Pitch: 4.5 in
• Blades: 2
• Material: Carbon-fibre composite
• Weight: 17.5 g
• Hub diameter / thickness: 16 mm / 8.5 mm
• Rotation: Clockwise (pusher)

Use the matching propeller direction on the correct motor positions and confirm thrust figures for your motor, battery and ESC combination before flight. Check arm clearance around the full sweep of the 12-inch disc, since heavy-lift frames often run these propellers close to the airframe.
