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

These are DIY micro quadcopter blade props measuring 55 mm (2.2 in.) for use with 6x15mm, 7x20mm, or 8.5x20mm coreless motors. It is possible to securely mount the propellers with a 0.95mm mounting hole onto 1mm 4-axial motors.
During flying, their flat surface can significantly reduce wind resistance. As a result, when the propellers are firmly fixed on the quadcopter, they may spin at a high speed with ease.
In addition, the propellers can withstand accidents because they are composed of high-tenacity steel. These four propellers, or let’s say two pairs (red and black), can be used to launch your minicopter or kept as spares until they need to be replaced.
