Don't forget in some multi bladed machines such as a 500D / E you have to balance the head with no blades on first. Highly amusing watching novice engineers/pilots trying to work out why they can't track and balance a 500 as they haven't done the head.
Other things that can effect lateral and verticals are the dampers, if you got a soggy one it will play havoc with the track and can upset the tail rotor. Had before TR balance problem at Ground idle, rotor would not respond to weight adjustments, when it did went from one side of chart to the other, cause dampers.
Other problems can be solved by placing weights in the stabilisers - common on 500.
Sorry this is 500 related, I know the machine best. 300' s seem to be more tolerant although a bad set of friction dampers can be interesting ie difficult to see the world when in auto. However I reckon a good set of friction dampers as good as elastomerics if not better.
Hope this helps, loof forward to a good topic here. Quick question normally use a bog std Chadwick how good is the 8500 worth the money.
Cheers guys
