Specifically assigned to achieve top speeds with high rpm motors, the AVAN-S Racing Drone Propellers from EMAX can push up to and past 100 mph when paired with RS2306 and RS2205 brushless steel motors. This pair comprises one clockwise and one counterclockwise propeller, each 5" long in a 2-blade configuration and made from clear polycarbonate. To achieve fast speeds, the propellers have been given a higher lift coefficient at a lower angle of attack. To help ensure these propellers stay in place at high speeds, they are equipped with a locking design for RS2306 and RS2205 motor hubs.
