A pair of very high quality GM 15 x 8 folding prop blades, suitable for HyperFlight's and other makes of folding prop yokes and spinners.

These blades are thinner (they have a higher aspect ratio) than normal folding propeller blades, allowing larger diameter blades to be fitted without pulling too much current. This increases the propulsive efficiency of the powertrain. They are also engineered to fold closer to the fuselage, and cause less drag when folded than other props. See photos 3 and 4 for a visual comparison of GM, RF and Aeronaut props, kindly produced by Andre Jeber Demetrio.

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.

Good quality, light weight and very efficient woven carbon cloth prop.

Super quality, I have several pairs of these blades. They do fold very close to the fuselage. They are also very durable despite looking (feeling?) fragile.

Delivered real quick to Australia along with some other gear in a sturdy cardboard box.
Unfortunately when fitted to a 38mm Hyperspinner, they won't fold all the way flat against the fuselage of my Super Ava Pro-e.

Superb. I have several pairs of GM blades, all very nicely made, light and fit well when folded. May require some light sanding at the root pivot point to get a smooth fold, but that's normal for any blade and not a criticism.

Superb quality.
Highly recommended!

 Review by:

These GM folding prop blades not only fold in close to the fuselarge, they appear to draw less current than the same size blades from Graupner or Aeronaut. They are more expensive but definitely value for money.
