The BX1306 brushless motor, available in 3100KV or 4000Kv  options.  These motors represent the perfect balance between performance, quality and price.  Sold in a pair of CW, and CCW motors,  the BX 1306 motors are build from a solid CNC motor bell and prop shaft which allows this motor to be lightweight and strong.  The compact design of this motor makes it ideal for your 150-180 size quadcopters with 4 to 5 inch propellers.  Although these motors are small, the high 3100Kv rating means they will spin very fast, powering your FPV quadcopter through the air with some serious speed. 

Please note the BX1306 3100Kv motors can also be used as replacement motors for the Tyrant 150, or the Crusader 130 FPV quadcopters
