Eagle,
thanks for the input! We just got a service bulletin about that and did adjust the RRPM, which now is running right in the specified range.
We did also a head inspection. On one of the dampers a rod end is pretty much at the limit, so this might have given a part of the rather rough ride, but I still believe it is the climbing blade.
I will track&balance tomorrow and put the blades in line.
We'll see how it goes.
One more question, do you guys T&B heavy or light?
A) Heavy, the machine has more inertia to dampen any vibration, but one has to pull more AOA to keep flying.
B) Less weight doesn't dampen as well but the bird will go faster for the max continous power data collection.
