Hello,

yes, the FDM for the Bo105, Aircrane und UH1 are tuned to match the data
given in some NASA Reports, in particular Report NASA-CR-3144 "A
compilation and analysis of helicopter handling qualities data. Volume
1: Data compilation", which is public available. This report contains
the most comprehensive data collection I ever found for helicopter. It
describes the static and dynamic parameters of five different
helicopter. E.g. control and power settings for a lot of different
flight attitudes containing the dynamic reaction for changing each of
the controls. Therefore I can note: As long as you stay within normal
operation limits the three mentioned flightgear helicopter behave(d)
very realistic.  For out-of-normal-operation-limits I have no data to
compare.

Best regards,
Maik
