The next plan for this issue is of a one third scale Lincoln Sport. The Lincoln Sport is a home built biplane, single seat, designed and built in the late 1920s and early 30s. This plan was designed by Pat Pattison and is sold by Scale Plans and Photo Service, 3209 Madison Avenue, Greensboro, North Carolina 27403. Phone: 919-292-5239. Price for the quarter scale version is $27.00. I don't have the price on the third scale version. Also available is a documentation packet about a quarter inch thick.

This airplane is pretty close to scale, both in outline and construction. The fuselage is built of quarter square spruce longerons, uprights and diagonals with eighth balsa formers and stringers. The seat, instrument panel and windshield are shown, and a very unique way of building the cabane pylon struts is shown. The landing gear is of 5/32 wire with balsa fairings, tape wrapped, and a straight through axle. The cowling is available in glass or can be built up of balsa, and a scale spinner is available. The fin and rudder are built up of balsa, and the shape reminds me of the shape on the Albatross fighters of WWI. The stab and elevator are also built up and are of a very unique and pleasing shape. The tail skid is built from brass and steel tubing and is functional with spring action ala WWI.

Since both wings are identical except for the center cut out on the top wing, only one complete wing drawing is shown. Ribs are from 3/32 balsa with spruce spars and false ribs. The tops are from laminated balsa. Ailerons are on the bottom wing only and are actuated with a belcrank system. Interplane struts are from plywood and are "I" shaped. There is a unique way of using aluminum for dihedral braces, but plywood can be substituted in its place. All rigging wire fittings are shown on the plan, and wires are functional with Proctor turnbuckles used for tension. A rigging diagram is shown on the plan.

The third sheet shows all former stations, a front landing gear view, an isometric view of the cabane pylon struts, and two views of the three engine cylinders. A pattern of the cockpit seat is shown as well as a top wing mounting view. This is an excellent plan for the man who knows airplanes and how they are supposed to look. I guess what I'm saying is, when you see a full sized airplane, do you see a large object or do you inspect it closely. Do you see how the ailerons, elevator and rudder are hinged, how the struts are attached, also the wheel pants and internal cowling baffles. All this information can be filed away in your memory bank for future use on some of your models. The man who drew this plan obviously looks at an airplane very closely.
