These
GM CL Competition Line prop blades are a work of art. The blades are specially designed so when folded they nestle very close to a fuselage to minimise glide drag, while still retaining reasonable efficiency under power. To facilitate this the hinge pin hole is angled in two axes to allow the blades to fold very close to the fuselage.
This requires the use of matching GM CL Spinners. These blades cannot be used on any other spinners, the pitch will be much lower.The blades are very light, so 800W is the maximum safe power level. Do not exceed this.
