The model must land on the carrier deck with the tailhook engaging one of the arresting lines stretched across the aft half of the deck to bring it to a stop. Models that represent full-scale carrier-based aircraft receive a bonus, and there are many interesting and often obscure aircraft modeled. Modelers with an interest in Naval history can find aircraft that existed for only a short time and perhaps only as a single prototype aircraft. John Vlna is particularly good at finding obscure aircraft, and he’ll probably surprise us again this year. At the last Nats, he brought out a model of the Ki-76 high- This Brewster Bermuda is one example of the obscure aircraft wing observation aircraft that was flown from Japanese that can show up in the CL Navy Carrier events. The Bermuda was modeled by Gary Hull. Profile Carrier models must use carriers in World War II. With many rare aircraft no suction fuel systems. longer is existence, the CL Navy Carrier events are likely the only place one can see some of these aircraft flying The Control Line Navy Carrier competition kicks off Thursday and it promises to be a good week of competition with some new models and some new contestants as well as most of the modelers who’ve been enjoying Nats competitions for years. With three days of competition, there will be plenty of Navy Carrier flying to watch. There are so many different things happening in the Navy Carrier events that there’s something for nearly everyone. CL Navy Carrier combines a variety of challenges for the modeler into a single event. The models are 1 timed for /2 mile from a standing-start takeoff from the simulated aircraft carrier deck to determine the high speed capability of the model. Speeds can reach nearly 120 mph. The pilot then slows the engine and model for a timed 1/2 mile at its slowest possible speed (as slow as 7-5 mph with the model hanging on the propeller). A combination of the two speeds makes up the flight score, Art Johnson entered these two models of the Grumman Guardian in the Nostalgia Carrier events. Nostalgia Navy Carrier gives a bonus for older model designs and older engines. The 33-inch-span model in front uses a McCoy 60. today—if only in model form. Thursday’s schedule includes Profile Carrier and the unofficial Sportsman Profile Carrier event. Thursday will be the high-performance full-body scale models of Class I and Class II with engine limits of .40 and .65 cubic inches respectively. Friday the rest of the unofficial events will be flown: Sig Skyray Carrier, .15 Carrier, and three classes of Nostalgia Carrier. The Nostalgia Carrier models can be some of the fastest models on the deck since the old (1952-1976) scoring system used in Nostalgia places a high scoring emphasis on the high- speed portion of the flying. The next CL Navy Carrier column will look at some of the models that will compete in the Profile Navy Carrier events. Come back throughout the week Scale models of the original aircraft are flown in the Class I and Class II for information on results, personalities, models, and, events.
