Dragonfly (oz8341)

About this Plan

Dragonfly. Radio control sport model.

Quote: "Slow flying 19-powered model is suitable trainer for the Tenderfoot who is ready for a larger engine and longer control lines. Dragonfly, by Harry Freeland.

THE Dragonfly was designed to be a little bit different from the average sport plane, seen at the local flying field. It had to be fairly easy to build, fly and transport. Most of all, it had to look like a real airplane. To these ends, I believe I have been successful.

Two models were built to test out the design. One was powered with an 0S Max 19, the other with a Fox 25. Both models flew, as they say, right off the board. Takeoffs and landings were a breeze and level flight was nice and groovy. If I ever get around to it, I'm going to try a symmetrical airfoil on this ship. I think with this type of airfoil, the design will make a really nice sport-stunt ship, capable of most stunts.

To some of you the landing gear arrangement may seem to present some problems on takeoffs and landings. However, I haven't encountered any problems with this gear.

Study the plans and gather the necessary material, and let's start building.

Fuselage: Begin by making up the fuse-lage sides. Glue one piece of 3/32 x 3 x 33 in balsa to another piece of 3/32 x 3 x 13 in, edge to edge, according to the plans. Both fuselage sides can be made from three sheets of' 3/32 x 3 x 36 in balsa. (The waste material can be used for the ribs and tip riblets.) After the glued sheets are dry, trace the side view on the sheet with ball-point pen. Notice that the top of the fuselage goes 3/16 up into the wing. Cut out fuselage sides.

Glue 1/16 sheet doublers to fuselage sides (I use contact cement.) Make sure you have a right and a left side. Mark motor mount location, firewall and all former locations. Glue motor mounts to sides with Ambroid, clamp, and let dry. Glue formers No. 2, 3, and 4 to one side, using a triangle to make sure the formers are 90 degrees to fuselage side. When dry, join to other fuselage side. Use bottom of fuselage to keep everything in alignment.

After this much is dry, add firewall and plywood piece No 1A. Leave rear of fuselage as is until later. Drill hole in plywood bellcrank mount for bellcrank and glue in-side of fuselage according to plans...."
