Snark (oz6776)

About this Plan

Snark. Radio control model for .35 - .40 power. Uses a foam core wing.

Quote: "Designed for a .35 - .40 engine, the Snark is tailored to flit the needs of the Sunday Flier. SNARK by Mike Hollison.

Snark was inspired by a collection of C/L stunt ships that the author saw lined up at a local flying exhibition. With a few modifications such as a wider fuselage to take the radio gear, a more substantial fin/rudder for stability, and a Sullivan molded foam wing, Snark was born.

The plane is a pleasure to fly, and both construction and handling are well within the capabilities of a reasonably experienced modeler.

Wing Construction: Snark has only flown with a foam wing: however, plans for a built-up wing are shown for those who prefer a more traditional approach. First of all, notch both leading and trailing edges for the wing ribs and epoxy the aileron hinges into place. Then, building one panel at a time, cement the ribs into position, add 3/16 square spars top and bottom, and fill in the space between them with 3/16 scrap balsa sheet.

Next, cut two undercarriage mounts from 1/4 ply, and epoxy a stack of three squares of 1/4 ply at one end for the torque box. Epoxy one mount in position, then cut the 1/8 ply dihedral wing brace and epoxy that in place also.

Cover one panel with 1/16 balsa sheed, after first gluing the scrap balsa wedge in place for the wing mounting bolt. Epoxy the remaining wing panel at the correct dihedral angle, then sheet and add the to rods, ailerons, balsa wing tips and locating dowel. Finally, fiberglass the wing center section and put aside.

The Sullivan molded roam wing is even easier to construct since one merely follows the instructions included in the package! However, a couple of changes need to be made to suit the design. First, each panel must be cut down by 8-1/2 in at the tip, reducing the length of each wing panel from 31-1/2 to 23 in. Next, the spaces provided for the landing gear blocks be filled in with a strip of 1/4 in sheet balsa, and a new space cut as shown on the built-up wing..."
