About this Plan

Heave Ho. Hand launch glider model.

Quote: "Be ready For those thermal-studded summer days - build this beautiful Class B hand-launch glider from the full-size plans! Heave ho, by Earl L Cayton.

Here's a hand-launch glider that's simple to build and downright fun to fly - a little 'cutie' designed both for sport and contest flying. This little ship will turn in flights of over half a minute for a fellow with an average throwing arm - and if you possess a pitching arm like Bob Feller, then the sky's the limit!

Construction: The plans are drawn full-size so merely join them at 'X', make reverse tracings of the right wing and stabilizer patterns for the balance of these parts—and start building ! The wing is made from 1/4 in medium soft 3 x 18 in balsa sheet. 3 in Jasco tapered stock is fine if available. Cut the tips to shape with a carving knife or a jig saw. Carve airfoil in roughly with a knife and wood rasp. Cut out a finger rest in the right wing - in the left wing if you are a southpaw. Finish off the airfoil with progressively finer sandpaper to 10/0.

Prop up the tips 1-1/2 and trim the dihedral joint to a flush fit. Now, cement the tips to the center panels. When dry, join the inner panels together at the center dihedral break in the same manner. After dihedral joints are dry, apply several coats of cement for increased strength.

The rudder and elevator are cut from 1/16 medium balsa and sanded smooth. The rudder and dorsal fin are made separately and joined when the entire model is assembled. Both elevator and rudder are sanded to symmetrical sections. Cut the trim tab in the rudder and attach it with copper wire hinges (see Plate 1B) .

The fuselage is cut from 1/4 x 1 x 17 in rock-hard balsa, or harder wood such as pine, bass, spruce, or cedar. Cut the necessary grooves for the wing and elevator, then shape the fuselage to the cross section shown on the plans. Shape the top rear part of the body so that the rudder will be mounted toed in 1/16 for a left turn. The dorsal fin is mounted straight ahead.

Before assembly, check the wing and elevator grooves for proper incidence. The elevator is mounted at 0° incidence and the wing is mounted perfectly level. Actually, the wing is positioned at a degree or so positive incidence, because the center of the leading edge determines the actual angle of incidence..."
