With the aerodynamic design these are some of the most efficient bullnose props on the market. With the thrust and power advantage of bullnose but without the inefficiency that is usually sacrificed. Paired up with the correct motors these are a serious contender for the fpv racing scene. Tested on the 2205-2600kv emax we got just over 1250g of thrust at 32 amps. Comes in sets of 4, 2 cw/ 2 ccw and black/red/green.
