This sounds like fun, but it imight best be not a new Carrier class but rather a new Scale class. In all the Carrier events, performance is what matters: going seriously fast, seriously slow, and getting it back onto the deck. Scale aspects are secondary. But for this new event, scale aspects are primary, and static scale judging , realistic flight and in-flight scale operations would be what everyone would go for, just as in Scale. So this is just a C/L Scale event where a Carrier-based aircraft is modeled and some of the required flight pattern requirements are carrier takeoff and landing.
Such an event might pick up entrants from both Scale and Carrier ranks. If you hold the event at contests that already have Carrier events, you could borrow use of the deck for a while for your flights. You'll need to provide your own scale judges as Carrier judges might not be up to it. Anyway, if you hold it near where carrier events are held at other times, you could possibly borrow the deck. (Also, many of us have flown off of decks marked on the ground, and that works, too. You can even do it with a deck set up on grass if you write the rules suitably. So all you really need is a set of bags and lines and some 1X2's.
