65MM (2.5inch) CW CCW Blade Propeller for 7X20MM 8.5X20MM Coreless Motor

These are 65 mm (2.5 inch) CW/CCW blade propellers for 7X20 mm and 8.5X20 mm coreless motors. The propellers with 0.95 mm mounting holes can be firmly mounted onto 1 mm 4-axial motors. Their smooth surface can greatly decrease the wind resistance during the flight. Therefore, the propellers can rotate at 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. Applications 1. Suitable for 90 mm-150 mm DIY Micro Quadcopter Frame Kits 2. For 1 mm shaft diameter Carbon Brush motor N20, M20, N30 3. For 1 mm shaft diameter, coreless motors 7*16 mm, 7*20 mm, and 8.5*20 mm are also compatible with brushed motors. Note: Available in red and black colors; you will receive a random one. Features: 1.
