These are 65MM (2.5inch) CW CCW Blade Propeller for 7X20MM 8.5X20MM Coreless Motor. 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) for your mini-copter just to take off, or hold them as spare parts for replacement.
