A set of 2 x 1045 Propellers. The set includes one clockwise rotating and one counter-clockwise rotating propeller with 2 x propeller shaft adapters. The adapters allow the propeller to be used with motors of different shaft diameters. 
This 1045 propeller can be used with brushless motors with a 800-2200 kV rating. With a low kV motor(800 - 1400 kV), this propeller offers smooth flights with longer flight times perfect for FPV and aerial photography. With a high kV motor (more than 1200 kV) this propeller offers fast flights perfect for acrobatic flights.
This propeller can be used with our A2212 1000KV, 1400KV, 1800KV and 2200kV motors and our 30A ESC.
Note: Buy additional propellers than required on your multirotor as propellers are regularly broken during flight crashes
