FGUK has been slowly working on an update for the original Bo105 that shipped with FlightGear. The team has branched out the original helicopter and improving it.
The WS70 never entered production but the British-built BlackHawk had 2 prototypes, one of them equipped with Rolls-Royce engines. Weird? Yeah. A bit. But FGUK is bringing it to the virtual world.
FGUK released a livery for the EC-135 for FlightGear but with a small twitch: they are asking you to donate to the actual Scotland’s Charity Air Ambulance if you get the livery.
