Skylark (oz753)

About this Plan

Skylark. 1940 old time gas free flight with eliptical gull wings by Louis Garami.

The Skylark (oz5383) was first published in Air Trails September 1940. This here is a later redrawn plan, printed in MB.

Quote: "Louis Garami's Skylark. Old Timer of the Month. Designed by Louis Garami. Redrawn by Phil Bernhardt. Text by Bill Northrop.

Louis Garami was one of the most famous of pre-World War II model designers. The majority of his gas model designs were small - primarily sport types, using the Atom engine and featuring inovative construction, such as rolled sheet fuselages. The Molecule (oz1057) was probably the best known of these. His Stratostreak (oz67) design is still winning in Old Timer and .020 Replica.

The Skylark was a departure for Garami in several ways, though still a winner in the 'clever design' category. It was developed for either Class A or B competition, using an Ohlsson 19 or 23, and carrying 320 sq. in. of wing area (It's interesting to note that the latest 1/2A Satellite also has a 320 sq in wing!). The fuselage is a faired diamond section, being built up from a flat frame crutch, and the wing is slightly gulled, with the leading edge of the inboard panels curving in to a shorter chord at the center section.

Plans for the Skylark appeared in the September 1940 issue of Air Trails (drawn by Paul Plecan!). Like many plans published years ago, no balance point was shown, nor did Garami mention balancing in the accompanying article. Considering the lifting stab, we'd suggest starting at 50%, or about 4-1/8 inches ahead of the trailing edge, and adjusting from there.

In terms of R/C, the Skylark should be a peachy little design with about an Enya .09 R/C on rudder, elevator, and throttle. Put in two 3/16 aquare rudder spars and add an extra 'rib' just above R-1, going aft. For an elevator, draw a line perpendicular to the centerline about 1-3/4 inches ahead of the trailing edge.

Install a 3/16 x 1/2 spar at this point and then add built-up or solid split elevators. Add a wire skid to protect R-5, and finally, move the balance point a little more forward."
