Vitaprop 8x4 Folding prop blades

A pair of high quality Vitaprop 8 x 4 folding propeller blades, suitable for HyperFlight's and other makes of folding prop yokes and spinners.

These blades are very high quality carbon moldings with an excellent aerodynamic design to maximise efficiency. They will tend to pull a little less current than cheaper folding propellers. They are designed for very high power levels and the blade root is reinforced with an aluminium bearing to ensure good folding, reduce wear, and maximise strength.

Note this product consists of two carbon 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.
