This update adds in the 2nd version of the Lynx - the Combat Lynx 3 which allows the Lynx to carry Hellfire missiles as well as a varied additional loadout. Both Lynx helicopters now have a suitable engine noise which I think is pretty close to a real Lynx. I have also re-written the Altitude Autopilot to now use a proper PID solution. The original wasn't far off but now the Altitude Autopilot can react faster and more accurately to required Collective inputs making for a very responsive and very stable altitude hold system. All helicopters have benefitted from the autopilot upgrade!
