[quote=gmcjetpilot;172309]Not all equip is the same and more over not all technicians and techniques are the same. The test should be done under power with the blades off the stop (constant speed prop) with the cowl installed.

"Off the stop". Does this mean prop to be pulled back as in coarse pitch?
Thanks

Default Helicopter AP/IA

Lost my regular AP/IA to full time work. Spent summer of 2020 on the ground trying to get a mechanic.

New AP/IA works on all the local Medvac helicopters.

Almost any helicopter mechanic can balance your prop.

Easy to see the difference. Spinner could be seen spinning in flight, now it looks like paint that is not moving/spinning.

Mine started out at 1.2ips, now .04. That after three runs lasting a total of about 20-minutes. Start/Stop/add weight.

Smooth as silk. Great investment for $200 total.

Mike

I've heard this before but if the blades are not tracking correctly or blade angles are not the same, it will cause an aerodynamic imbalance which cannot be 'fixed' by balancing. If blade tracing is out of limits balancing is generally not possible.
