Downloaded this recently and I think this is a nice helicopter but needs a small edit to the panel config file.
The following needs to be done change the line that reads - gauge16=bell_206b.airspeed,etc
to - gauge 16=bell_206B!airspeed
and - gauge 00=bell_206b.airspeed
to - gauge 00=bell_206B!airspeed
this simple fix means you can now sea the ASI.
