The same technology used to dynamically balance an airplane propellor is used to
balance helicopter rotors. It does not matter what the angle of the rotating
disk is with respect to the earth's gravitational field. It is measuring the
rotating mass imbalance with respect to its rotational center axis.

I'm with Thom,
I to balance props and have owned a helicopter. The angle won't make any difference.
It is the rotating mass. You do not need full in flight rpm. I use 4800-5000
on the ground to balance. This depends on each persons prop rpm setup on
their individual plane. The balancing instrument doesn't care because you just
plug that number in and it gets divided by 2.43 any way because we have the gear
reduction.

...I doubt there's anyone doing this within a few hundred miles of me. (Central
Colorado) ....
Many active FBOs with repair stations offer dynamic prop balancing. They are getting
more and more common as the price of equipment comes down. If I was doing
mechanic work even half-time, I'd buy one but I'm still trying to be retired
and only do actual work on other's airplanes once in a while.
