The heli is stock except for KDBB ED Lime Green dampers and tail boom support brace. The head and tail rotor system are buttery smooth.
I noticed that the verticle tail fin has a high frequency resonating effect / vibration during flight/hover while in idle up mode at 85% throttle (don't know the head speed) and maybe 5 degree pitch. There was no tail wag.
Is this tail fin vibration typical/normal? If not, what should I check?
Thanks.
