@David Chow  David is this by chance the weldment you are talking about on the collective cross shaft?  For the Aset Governor?

No the weldment is near mid point of the cross collective shaft. two vertical weldments a few inches apart for mounting the governor. I've seen about a dozen frames that had them. For most airframes The aset of comes with a bolt on weldment that attaches via two an4 you have to drill to mount the governor.

I've installed 16.   Mark has installed close to 30.   I believe there is close to 100 in circulation.  It is a great addition to a well flying rotorway.   With a turbo it's even better because it does the rpm chasing for you.  Because the turbo has so much excess power you're either over or under especially with aggressive maneuvers.   It feels like the governor reads your mind and anticipates the need for throttle change. 

I just came back from a track and balance job and found one of the governors incorrectly installed.   The installer pulled power from engine management and turns out it did not have enough power and droops the voltage under load.  I spend a good part of a day trying to figure it out.  It's a dynamic issue because the voltage will only droop when the governor is under load and is actively adjusting.  The governor would work sometimes and other times it would lose the rpm.

The install instructions specifically ask to tap directly to the battery.   So if you're installing one, please please follow the install instructions.
