HQProp Multi-Rotor 11x4.5R Pusher Propeller 2CW

The HQProp Multi-Rotor 11x4.5R is a two-blade, clockwise pusher propeller built in a carbon-fibre composite for large multirotor and heavy-lift airframes. Pusher propellers sit behind their motor rather than in front of it, so the blade pitch and rotation are matched to that reversed airflow before you fit one.

Key features

• Two-blade pusher design supplies the clockwise rotation needed for pusher-position motors on large multirotor layouts.
• Carbon-fibre composite construction keeps the blade stiff and resists flex under the loads an 11-inch heavy-lift prop sees in flight.
• Ships with a set of shaft adaptor rings (6/5/4/3mm) alongside the standard shaft sizes, so one propeller mounts to several different motor shaft diameters without a separate hub purchase.
• Supplied as two clockwise propellers for the paired CW positions on a compatible frame, rather than a complete four-propeller set.

Fit this propeller only on the pusher/clockwise motor positions of a compatible large multirotor, and confirm the motor shaft size against the supplied adaptor rings before flying. Balance each propeller and check tip clearance across its full arc before the first flight.
