Frequently Asked Questions

What is a pusher propeller and when is it used?

A pusher propeller is designed to be mounted on a motor with a standard clockwise (CW) rotation but is intended for use in a 'pusher' configuration, often on the rear of a multirotor or specific aircraft design where the motor is mounted backwards. This setup is used to achieve specific flight characteristics, counteract torque, or in custom layouts like certain VTOL and hybrid fixed-wing drones.

Are the included adapter rings necessary for installation?

Yes, the adapter rings are crucial for a secure, concentric fit and to minimize vibration. The propeller hub is designed for a specific shaft size, and the included rings (6mm, 5mm, 4mm, 3mm) allow you to adapt it to fit your motor's shaft diameter precisely. Always use the ring that provides the tightest fit without forcing the hub.

What type of multirotor builds are these 8x4.5R props best suited for?

The HQProp 8x4.5R props are ideal for 8-inch class multirotor builds prioritizing a balance of thrust and efficiency, such as long-range FPV drones, aerial mapping platforms, or heavy-lift photography rigs. The 4.5-inch pitch offers good static thrust while maintaining reasonable cruise efficiency for extended flight times.
