Wakefield Winner (oz5395)

About this Plan

1939 Wakefield Winner. Dick Korda's Contest winning model. Here is the article and drawings as they appeared in the November 1939 copy of Air Trails.

The model was later kitted by Megows see Wakefield Winner (oz420).

Quote: "THE Wakefield Contest was over almost before it started. Dick Korda's first flight - in fact, the first of the contest - was a heartbreaker for the other contestants. Not only was the 43:15 flight the longest of the day, but it also set a new international record.

Korda's record-breaking formula is a simple job expertly handled. The model is a development of the basic design with which Chester Lanzo, Korda, and others have been knocking off the prizes for years.

Most interesting feature is the folding propeller. There is nothing new about flop-back props, but this one is unusually perfected. The slanted hinge enables the prop blade to fit perfectly flat against the side of the fuselage, The counterweight, bent back when at rest, tends to straighten out through centrifugal force when the propeller revolves. The resultant reaction balances a similar force exerted by the thrust of the single blade.

Korda's 1939 model and its predecessors have amassed the following wins: 48 minutes, by Chester Lanzo, to take first in the 1936 Nationals, second by Dick Korda with 12 minutes; first in 1937 Nationals, 54 minutes by Korda, third in both Wakefield and Moffett eliminations the sante year; third in the Wakefield eliminations and winner of the finals in 1939. The model set a world's record of 43:15 in these finals.

Materials, sizes and quantity are listed in the Bill of Materials at the end of the article.

Construction. Fuselage: The assembly drawings are quarter scale, details full size. Dimensions are given for the preparation of full-size working drawings. Structure is simple. Longerons are pinned oil the working drawings. and the cross pieces. and diagonals cemented in place. Both side frames are made at once, one superimposed on the other. Pins should not be driven through the wood but rather along the edges. Wax paper spread over the drawings will prevent adhesion of the work to the paper. Let the cement dry overnight. If the two side frames stick together, separate them with a sliver of a double-edged razor.

Assemble the sides by starting at the widest section of the fuselage. Cement cross pieces in place at Stations 7 and 10. Note that from Station 7 to Station 10 the top cross pieces are cut from 1/8 sheet balsa to match the dihedral of the wing. Rest the fuselage inverted on the bench to check alignment of cross pieces. Pins can be used to hold the work in position. A triangle rested on the bench and against the fuselage will help. When dry, draw the two ends of the fuselage into position. A loose rubber band will held the nose properly..."

Update 4/6/2024: Replaced this plan with a re-scaled version now at fullsize, thanks to HobiePilot. This now shows correct full wingspan of 44 in on sheet #1, and a wing rib with chord of 5 inches on sheet #2. Have separated the article pages as a supplement file.
