Please slog around on this site to see how the military launched gliders by soldiers to use as targets

I printed plan on A3 sheet paper and bought A grade balsa sheets. Ready to stick paper and cut. Very Happy

Levent, Looks great so far. Is A3 a special thin (tissue like) paper? Or sticky on one side? I have been thinking of building these planes based on your super color cutouts, but thought if using regular copy paper it would be to heavy. Plus, I haven’t figured out how to make or install the dihedral brace. If you complete the glider, please show how those pieces are made and installed. THANKS!

Marleysky, thanks for kind words. It is laser print plain paper, not tissue. Printing on tissue is better, however I couldn't find a printer company to print tissue. It is thin and can be stuck between rollers. It will be a little heavy, but I choose very light balsa sheets. I am going to made wings from 1 mm sheet, instead of 1/16" sheet, approximately 0.5 mm thinner. Fuselage is same thickness as in plan, 4.5 mm sheet, because the wing pivot may not work properly with thinner fuselage.

Dihedral brace in plan is made of thin aluminum, so it can cut the thin balsa sheet wings or may be bent when the wings opened. I am going to made it from 1.5 mm ply.

I am going to send photos.

Update: Plain paper is unsuccessful because tail is heavy. Too much lead weight needed for nose weight. Using marker pens is a must for coloring folding wing gliders. Contest grade very light balsa must be used in construction.

Mine looks "OK” it printed out on a standard letter sized sheet. Windows upgrade took away my printers ability to do poster or tile printed plans. The Interceptor Drone will only be 9” long and 10” wingspan! I think I’ll wait til I can get a full size printed out.

Perhaps printing directly on balsa sheet is better than marker pens which is time consuming.

Try two small neodymium magnets for nose weight instead of lead. Practical.

Using neodymium magnets as nose weight. Aplying a little glue on magnets is good for catapult launching.

A3 refers to the size of the paper (metric), A4 is the nearest size to "letter" and A3 is like two A4s side by side.

I hope we return to Imperial measurements now that we are leaving the EU.

This just an untested W.A.G. (wild-ass guess), so try at your own peril:

Stick some tissue to a sheet of regular computer paper with a coat of nitrate dope and allow to dry. Then print your designs on your laminated tissue. Detach the tissue from computer paper with thinner and re-attach to the desired surface with more dope.
