This weekend I have been struggling with Rory Kelly's CH-46 and CH-53. It should be possible to convert these helo's to AI models, but it got me very frustrated

I think I tried just about everything. First I merged the original files from hovercontrol.com with the files in 'ai_helos.zip' by Holger Sandmann and Rob Nieuwenhoven. To check if they would work, I changed the FDE type from AI to normal, and then they showed up nicely in the aircraft selection menu in FS9. But: they didn't show up as AI in the sim.
Then I downloaded a complete miramar AI package from flightsim.com (knkx_ai2.zip), including both helo's. I suspected there was something wrong with the .air of aircraft.cfg files. No luck. Still no AI helo's in the sim.
The CH-46 and CH-53 just don't show up at any field. When I replace the lines in Aircraft_KNKX.txt with any other AI model it works just fine, so it can't be the AFCAD or flightplan. Parking for the helo's is available; radius, codes and types do match.
I have several AI helo's in my sim, some of them modified with the forementioned files from Holger Sandmann and Rob Nieuwenhoven. All work fine, except the CH-46/CH-53. Such a shame as I'm working on a package for Camp Pendelton

So: long story short: does anyone have the CH-46 and/or CH-53 flying as AI? Would that anybody please help me?

Cheers!
