Hey Cease,
I've built a dozen CH-53s in /72. Four models were used on a ship dio, some were put in sqn. disply cases to compare Nato-to-Soviet acft, and a few were used in transfer/retirement plaques. I have another eighteen -53 kits spread out between /144,/72,and /48 scales solely for my own enjoyment now. The /144 scale helos are to used in a dio with a /144 c-130 to HONOR/NEVER FORGET three of my friends/sqn mates who never came back from the aborted 'hostage rescue attempt' (iran) of '80.
Sometimes I think there is something about the lines of an acft, just like the lines of your car (why did we buy it is the first place) that keeps drawing us back. I initially joined the service to be an electrician on the F-4 but was put into helos because of a higher mechanical score. I never tire of looking at F-4s, after doing some more helos I might start one of my eight F-4 kits.
