55mm (2.2inch) Blade Propeller Propeller for 6x15mm, 7x20mm 8.5x20mm Coreless Motor DIY Micro Quadcopter

These are 55 mm (2.2 inch) blade propellers for 6x15 mm, 7x20 mm, and 8.5x20 mm coreless motor DIY micro quadcopters. 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 and black), 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.
