Great Lakes Trainer 2T-1A (oz108)

About this Plan

Great Lakes Trainer 2T-1A. Scale model for control line of 1930s trainer.

Quote: "Full size plans and build-it data for a .19 to .23 powered flying scale model of the 1932 2T-1A Special Great Lakes Trainer.

For those control-line modelers who love scale models, we introduce one of America's favorite training planes of the early thirties, the Great Lakes 2T-1A. Several commercial flying schools used this trainer exclusively and a good many sport fliers owned the Great Lakes because of its beautiful flying characteristics.

The Great Lakes 2T-1A was manufactured under the ATC No. 228 by the Great Lakes Aircraft Corporation, Cleveland, Ohio, in 1932. It is a two-place, open, land biplane, powered by the American Cirrus Mark III, rated at 90 h.p. at 2,100 r.p.m. Cruising speed is 90 mph, top speed 110 mph, landing speed, 40 mph, license number NC 856K.

In 1933, this model was rebuilt by the Minnesota Aviation Sales Corporation into a stunt plane for Air Show work. It was equipped with an inverted, flying carburetor and fuel system, heavier flying and landing wires, doughnut wheels, and fairings about the strut ends and the lower wing panel where wing and fuselage join. The front cockpit was covered. These changes raised the top speed to 120 mph and cruising speed to about 110 mph.

So much for the history of this plane, now let's build a winning scale model of this beauty from the full-size plans herewith. Fuselage: The frame is built up of 1/2in square medium-hard balsa. Build the two side frames and then cement in the cross members which are also 1/2in square. Leave out cross member 3. Cement the 1/2in plywood firewall in place, then the formers at stations C-C, D-D, E-E, and F-F. Next, cement in the 1/16in ply-wood rudder post. Now cut out the fin and groove the inside face of each piece so that they will fit together flat with the plywood rudder post sandwiched in between. Cement and clamp together. While this is drying, install the two hardwood engine mounts..."
