A pair of economy 4.1 x 2 pusher folding propeller blades with a folding spinner assembly suitable to 1.5mm motor shafts. If not used with the supplied spinner/yoke assembly these blades will require a smaller spinner/yoke with 1.5mm diameter hinge pins.

Although supplied for pusher use the hinge pins can be pushed out and the blades refitted for normal tractor (pulling) operation.

Suitable for use with our Sunnysky R1106 motor and HyperFlight 28A ESC powered by a small 2S LiPo battery. Note this motor's shaft it not a very tight fit and a little CA will be needed to secure the spinner.
