Portable Control Line Aircraft Carrier Deck
March 1962 American Modeler
Here is a clever control line airplane carrier deck design that derives it lightness from sparse construction and its compactness from making the modular components stowable within each other sort of like the familiar Russian matryoshka nesting dolls. It is designed to accommodate a 60' circle, but slight modifications to the deck components can be easily made for other radii. Not shown in the plans but likely possible without sacrificing strength and rigidity would be to drill lightening holed in the 1"x6" and 1"x8" frame members.|

Usually a man's dedication to an activity is indicated by the lengths to which he will go to become proficient in that category. This practice deck is a good indication of Ray Randall's dedication to the Navy Carrier Event. We found out about it at the Nats where most flyers were having trouble getting on ye old deck while buffeting the breezes. Ray got on first pass, two times. Since a standard contest-type full deck is fairly expensive, most people are forced to practice on flush decks. This just ain't the same as landing on a regular deck.

So we offer construction data on this portable practice deck to enable you and your club to get good with carrier landings. The arresting area, a bit shorter than standard, will sharpen your procedure. Take-offs are from the ground, or if you can get off the forward section, fine! The deck, transportable by automobile, sports its own dolly system for maneuvering on the field. Arresting cables and sand bags are according to the AMA rules book. We offer two types of material list - one if you need the wood cut to length by your lumber dealer, the other for standard lengths of wood. Grade BC plywood finished on one side is cheaper than AB. A table saw will greatly ease the labor. We strongly recommend screws for frame assembly and glue for decking assembly, but nails will suffice.
After cutting all lumber, construction entails fairly conventional carpentry. Side frames are assembled using the deck pieces to align them. Be careful to build Forward and Aft decks so their beveled ends face each other. You'll note from the plans that the aft deck must fit inside of the forward deck for traveling. Check this fit before you get too far along to change it if need be.
The 1/4" plywood decking should be glued with white glue or Weldwood and nailed at 6" intervals. The stern ramp uses a 1 x 6 brace across the front end; rear end is not reinforced. So don't walk on it! Let's not forget the 1 x 2 cross members under the decking. Although they stiffen the plywood, we don't recommend that you climb on the deck. It has been kept light so you can move it around. Remember... it's for models, not people.
The dolly has four 4" casters, 2 swiveled and 2 fixed. The swiveled casters are on the two-rope end for maneuverability. Adjust these with spacer blocks to raise the dolly's deck 7" off the ground. Tow handle should be wide enough to fit two hands. You doll this up as you wish.
Ray finished his deck with gray Latex paint. After painting, install cable guides, spacing as per plans, driving screw eyes into side frames. Center of the eye should be 1" above the deck. Too high and you'll trip your airplane on landing.
For transport on car top carriers, the assembly is in this order: (1) Aft deck on carrier is upside down. (2) Ramp in center of aft deck. (3) Dolly on top of ramp right side up. (4) Sandbags, cables, tools in ends. Chock dolly wheels with sand bags. (5) Forward deck over all as a cover. (6) Tie the deck package on securely, also use fore and aft restraining rope tied to the bumpers of the car.
For transport on the flying field assembly is like so: (1) Dolly next to ground (wheels down, please). (2) Rest of assembly - just as atop car.
The deck approximates a 60' radius at the center-line. When locating your center marker, check at both ends of the deck with your airplane. That's about it. The rest is up to the amount of practice you do. For maximum fun, float the deck in a lake and use Real Water. - Happy Dunking!
