it s a fist public demonstration.
There was only one flight. The gearbox of the main rotor broke down. A plastic gear wheel turned on a steel shaft. I will change the shafts to carbon. Carbon shafts are easier to glue

Here is test flight # 1 and # 2, 1st flight she flew! 2nd flight the tail rotor belt broke and she tipped over and broke the main rotor hub, will repair and try for more flights, she needs nose weight and more power.

Ok, here is the power test with main rotors on, looks very unstable and wobbly, I will have to go with a ridged rotor system on this one, it will only take a day or two to redo the rotor head no biggie, here's the video.
