EDF-70 4 CELL COMBO: Comes with the original bolt in BL2847-3575Kv in runner motor and is factory assembled & balanced, runs smooth out of the box. Designed for 4 cell battery packs, this fan puts out approx 1.5kg thrust at 850 watts. Care should be taken when running in hot climates, dont fly it flat out the entire time, and cool down running should be done after each flight, approx 60 seconds at the lowest speed helps to draw heat out of the motor.

NOTE: All our stock is the original Lander fan unit from mid 2009 with the superior wemo copy rotor, performance in the air is noticeably better than the current Lander 70mm fan with the chinese design rotor.
