And my test was just blowingair on the scale...my be more with a real thrust mesurements device.

Correct. I get similar results, but the rule of thumb is that you lose about one third of thrust once the unit is in the plane (see link below). So that means 680gm becomes 453 gm in real life! As far as sound, my pre-balanced 6S 70 mm Powerfun Fan motor combo unit sounds the closest to a jet turbine than anything I have ever had before. Light weight, lots of power, no vibrations at all no motor sound.
