Our in-house manufactured folding propeller yoke mounts to any race quad motor with a 5mm threaded shaft for low power pusher prop applications (Under 200W). We have not tested the blades upper RPM limits, the small hubs on the blades will be the weak spot. Great for flying wings and other small pusher designs. Cleaned up aerodynamics when the motor is off, and far less busted props when landing! Here it is on a small flying wing: (Note the small dental rubber band that ensures a streamlined closure.) We offer a few sizes of propeller blades what will fit: 4.5x3, 5.1x3.1, 5.5x3.3 Equipped with integral forward and rear blade stops so they won't cross over themselves or come forwards and eat your trailing edge. Can be equipped with a rubber band for assisted folding, offering super low drag. Here it is on our Carbon Falcon kit: Specs: Blade Retaining Pin Spacing: 21mm Blade Retaining Pin Diameter: 1.5mm Yoke Length: 25mm Yoke Width: 4mm Yoke Thickness: 7mm Blades not included You will need to turn on the "brake" setting in your ESC to stop the blade from spinning and allow it to fold. Hot trick - If you can place the motor and prop further away from the wings trailing edge, the prop will be much quieter. If you want to make a bunch of noise, then cut out the trailing edge like the photo above. NOTE: If blades do not swing freely in yoke, lightly sanding the blade roots to remove slight molding line.
