Congratulations!
I am surprised by the low vibration levels on a flexbeam rotor. Is it only an improvement over the old 2-blade rotor, or is the vibration level even low compared to other 4-bladed rotors?
I find it also strange that there are limit stops for the flapping angle. The Ansat does not need limit stops, neither does the EC135, nor the BK117/H145. Is there a special reason for this?
