Thermic Trio (oz10706)

About this Plan

Jetco Thermic Trio. A set of three all-sheet balsa chuck gliders, with three diffrent layouts: conventional, canard and flying wing.

Quote: "Put 'fun in your flying' with Jetco's easy-to-build easy-to-fly model designs.

Instructions.

1. Study the drawings for the construction of each model. Remove the wing panels from the balsa sheet and glue these together at their proper dihedral angles.

2. Cut the fuselage to size and shape. The drawing is full size. Draw with a pencil the amount each fuselage is to be tapered and then with a razor, remove the surplus wood. Use several light strokes until the wood is cut thru. A ruler may be used as a guide.

3. Notice that the flying wing has ailerons cemented on the wing tips. The ailerons are raised up slightly in the rear. Cement on the triangular ailerons sets to hold the ailerons in the proper position.

4. Cement the wings and tails to the respective fuselages. Be sure the rudders are on straight without a turn. When the cement is dry add another coat for added strength.

5. All of the models will need a bit of clay on the nose to balance them for flying. Gently glide any one of the three models. If the model goes in a repeated series of up and down motions (stalling) add more clay to the nose until a smooth even glide is obtained. I the model dives into the ground, remove nose clay.

6. The canard may be flown with a rubber band after it has been balanced for the glide. Link some light rubber bands together until they are about 12 inches long. Slip the rubber in the wire hook (make from paper clip) stretch out the rubber and release the model pointing upwards. Be careful and do not point the model at any person when launching it."
