This highly efficient OS motor is intended to be an electric equivalent of the .52 class 4 stroke engine or .40. class 2 stroke. The KV has been chosen so that it works with closer comparable propellers to engines. By fitting an APC 14 x 7E and using a 4 cell, Li-Po battery you can get 9600rpm maximum and thrust of 4kg! To get this performance will require an efficient ESC and a battery that can deliver this current constantly. By going to the 12 x 8E propeller the speed can be increased.
