0.9mm 55mm 4pcs Two-Blade Mini Propeller Coreless Drone Motor Fan

2-Blade Propeller Propeller for 6x15mm, 7x20mm 8.5x20mm Coreless Motor DIY Micro Quadcopter

These are 55mm (2.2inch) Blade Propeller Propeller for 6x15mm, 7x20mm 8.5x20mm Coreless Motor DIY Micro Quadcopter. The propellers with 0.95mm mounting hole can be firmly mounted onto 1mm 4-axial motors.

Their smooth surface can greatly decrease the wind resistance during the flight. Therefore, the Propellers can rotate in high-speed easily when reliably mounted on the quadcopter.

Besides, the propellers are made of high-tenacity material and thus can sustain crashes. You can have these 4 propellers, or let’s say 2 pairs (red and black) for your mini-copter just to take off, or hold them as spare parts for replacement.
