Last I heard was that he was reluctant to release this and having beta tested it I understand why. I am still testing (last night I used it to fly formation from ARK2 to ARK3 (Devon to Gibraltar) in the Iris Phantom FG1, accompanied by its older DSB brother as AI).
The system does work, but it's implementation into each aircraft is the area of trouble. In some planes it just won't work, certain autopilot gauges interfere with it functioning correctly. So you may need to swap gauges, and then you have to purchase and set up the radar gauge for each panel. Then it all depends on wether the aircraft has a fully functioning auto-pilot enabled, if it doesn't, you will have to edit the aircraft.cfg and/or the air file to fix this.
So, that leaves it at editing almost every important file within the aircraft container, quite advanced stuff for some folks and would lead to a huge amount of support questions for Rob. I wouldn't envy him.
Plus to get the best of it, you would need AI tankers, so that's another skill required, TTools and YRoute, etc. You can hook onto any AI and refuel, but topping up a Viper from a Cub, whilst it may be possible, is just plane daft, pun intended.
Also, you can't use it with Rob's VTOL or Helo gauges, they conflict. So I have a separate panel for my Sigma Harrier without the VTOL gauge for those long, non VTOL ferry flights.
Saying that, if you know what your doing, it's a hoot, and I'm still learning :friday:
