Ok guys, got some news.
I got a reply from Revell Germany and they've forwarded my request on to their development department. So, I guess that means... start bombarding them with emails! I tried to contact straight Revellogram, but their website is impossible to find any contact information on. So, our foot's in the door.
Marke,
I'd love to have seen operational Cheyennes too, but there were definite issues with the bird. Having spoken to a few veterans involved with the program now, I've gained a little insight into it. Lockheed and the Army kept pushing for more speed, which increased vibration and ended up causing a fatal crash which was a major factor in killing the program. Usually not a good thing when your rotor vibrates so much that it comes down through the cockpit.
As far as seeing them in Vietnam and the outcome being different, I think there are a few Snake pilots on this forum who'd disagree. Better than the Apache? Nah, faster, yes, but not better. The Apache took a lot of the Cheyenne's technology and improved on it. As was said in a discussion I had the other day "there is a lot of Cheyenne DNA present in the Apache". It was a great machine, and I'd certainly love to see one fly, but its day has come and gone.
That being said, the Cheyenne did a great deal for the Attack community. Most importantly, the AAFSS project established Attack helicopter doctrine that was used effectively in Vietnam and set the foundation for the armed helicopter.
