Description

A pair of economy 7 x 4.5 folding propeller blades, suitable for HyperFlight's and other makes of folding prop yokes and spinners.

These nicely made plastic blades are suitable for use with smaller electric models.

Note this product consists of two propeller blades only. The central spinner/yoke assembly is not included. Also it is common for prop blades to not fit all spinner/yokes perfectly as supplied. It is often necessary to reduce the width the blade root slightly to ensure free folding movement. Also the cut out in the spinner cone often needs to be increased to allow the blades to fully extend. The root of the blade should not touch the spinner cone when the prop is fully opened.
