This is a kit for the latest propeller design for Josh Finn’s Girder Grabber F1R design. Includes a 15×20 prop block, laser cut, double tapered spars, laser cut ribs, precision stripped blade outlines, and .010 wire prop shaft.
This is a no-compromises kit for propeller blades only. It is not for beginners, as the components are extremely thin and fragile. You will need to supply your own covering jig, covering film, and pitch gage for mounting the blades to the correct pitch.
