I played with Holgers Starter Kits and have using his AI choppers and my own afcads and schedules set up a full helicopter flying airfield at an Airforce basein my region
By following his instructions re AI helicopter downloads and using his guidelines for AFCAD design it was easy,the only problem I struck was A/ C radius which you couldnt alter with AITM as it doesnt appear there.
Solution was getting it from the A/C cfg file
By keeping the taxiways short it makes it look very realistic
It adds a new dimension to AI and there is no reason it should not work on a normal AI airfield as long as you set up special runways for chopper ops using an overlay

Must learn to repaint to fit in with my local Air Force colours
