Hallo Kluftinger,
thanks for explaination.
case 1:
i hade done a test without the main and tail blades, (still with the flybar and the rotor blade holders), full throttle, main rotor speed ca. 3800rpm .
i got 130-160 extrem vibration.
something is wrong in the mechanics, right?
Case 2:
without blades, with out flybar, without main rotor head, only keep the swashplate, main rotor speed ca. 2600rpm
the vibration looks ok?
how about the tail vibration? too strong?
i have touch the tail rod, it vibration a little bit strong, just my feeling.
