Flipstick (oz16006)

About this Plan

Flipstick. Simple hand launch glider model. Wingspan 16-1/2 in.

Quote: "Some glider, we'll say - and so will you! Flipstick, by Louis Bucalo.

THERE isn't much I can say that will fully describe the performance and beauty of the 'Flipstick'. Use of polyhedral and high wing-low tail give this glider a flat glide and a quick pull-out from bad throws. This ship is solidly built. Do not fear a little extra weight because it is weight plus 'oomp' technique that gets the glider up. The design and adjustments keep it there. You can best be convinced by getting th work and proving the efficiency of the Flipstick to yourself.

The wing is made from balsa 3/16 by 3 in. Use a grade ranging between soft and medium. Because the wing has four panels instead of two, it is imperative that very strong cement joints be made. Sand each panel to an accurate rib section, coat the butt end with cement and allow to dry.

After each panel is cemented to the adjacent one, four additional coats of cement are applied with a brush. Silk is then glued over the joints insuring strength as shown in the plans. Brushing the cement on forms a smooth, neat-looking skin. Each coat should extend 1/2 in over each panel and should be permitted to dry before the next is applied. For a slick finish, apply four coats of clear dope, sanding after each is dry, with wet-or-dry sandpaper.

Warp in a slight wash-in on the right wing (increase of angle of attack near tip) and slight wash-out on left wing. The right wing is seen in looking forward toward the nose. of the ship from the rear.

The fuselage is made either from light 3/16 flat pine or rock-hard 1/4 in balsa. In the original ship, pine was used. Shape fuselage as shown on the plans and sand to given cross-sections. Remember to enlarge the plans of the fuselage as it is shown half-scale. A 'V' cut is put into the top of the body to hold the wing. Sand the fuselage well and repeat the finishing procedure used on the wing.

The stabilizer (shown full size) is cut from 1/8 sheet and finished in the same manner as wing and fuselage. The rudder is shown half-size so it must be enlarged. Using 3/32 flat follow same procedure as in stabilizer.

Cement wing and stabilizer to the fuselage as shown on the plans. Check perfect alignment. Cement the rudder in place and set it for a slight right turn. The wash-in of the right wing will prevent the ship from banking too steeply. Apply four coats of cement over the wing-fuselage joint.

The glider is thrown into a slight right bank and glides to the right. Pull-out is automatic, and because both climb and glide are to the right, no altitude is lost. In testing the glider, make four throws, gradually increasing the speed of each.

Better put your name and address on your Flipstick and 'flip' your model success to its zenith. "
