I tested this unit on my test stand and here is what I got. 71 amps, 1030 watts, and 1.3kg. of thrust on 4S 60C 3300mah battery. This is probably the most powerful 64mm fan unit I have personally tested. But like everything there is no free lunch. This means you will need to use a 70 amp esc minimum with good airflow. an 80 would be better. You also should have a very high discharge battery, at least a 45C discharge. this thing is going to drain your battery fast. The unit looks good and the motor is quality but I don't understand why they cant use decent bearings. Mine are already noisy. If you want to run it on 3S I tested it and it produced 48 Amps, 555 watts and .9 kg of thrust. Best dollar value out there, especially with free shipping. My numbers far exceed what they have it rated for. I think this would be an excellent candidate for a 10 blade fan as well.
