The xrotor 2306 series has been specially designed for the use in pro-freestyle and speed racing. Thanks to the very low cogging torque, the engine runs almost by itself. The design-optimized propeller holder prevents the propeller from slipping if it should hit or crash. With the 2306 motors, the balancing act between extreme durability and minimum weight was also successfully achieved.
