This is a pack of 8 5x4.5 bullnose inch propellers; 4 x CCW and 4 x CW propellers. These propellers are made from a strengthened ABS plastic meaning that they can cope with a much higher force (such as that experienced when using powerful racing motors). The added feature of the bullnose design can increase the performance (i.e. thrust produced) by over a third compared to your standard propeller design.
We have a choice of three colours; orange, green and black. Perfect replacements for your broken props on your mini quadcopter.
