About this Plan

Record Breaker. Hand launch glider model.

Quote: "A High Performance RECORD BREAKER. How You Can Build and Fly the Class 'A' Indoor World Record Glider. By Leo Vartanian.

IF YOU are one of many model builders who have not enjoyed the fascinating sport of indoor model glider flying due to lack of plans for this type plane, the little glider presented herein should be enthusiastically received.

This little model, though simple enough for any novice to construct satisfactorily, will appeal to the most particular of experts, due to its fine design and high performance.

At record trials held last winter by Chicago Aeronuts, this glider amazed modelers by recording the hitherto unheard-of time of 54.3 seconds. Best unofficial flight was 55.7 seconds, highest ever recorded by an indoor Class A glider.

Although primarily an indoor glider, it may be flown outdoors on calm days with most gratifying results such flights average about 45 to 50 seconds. Flights of many minutes duration, frequently out of sight, have been obtained when flying outdoors. By carefully following the plans and instructions any model builder can build this Class A glider: a definite threat in any contest.

Wing and tail surfaces should be made from very light balsa, preferably 4 to 5 lb weight; the fuselage is made from fairly hard, straight-grained balsa. All wood used should be quarter-grained if possible.

Wing: As the wing is the most important part of the completed model, extreme care should be taken in making this part. Obtain a piece of balsa, of specified weight, 3/16 thick, 3-1/2 wide and 12 in long.

Begin by making a cardboard pattern of the complete wing outline and tracing around it on the balsa. After cutting and sanding the outline to shape, sand it down to 5/32 thickness. Taper the wing from this thickness at the center to about 1/64 at the tips.

The next step is sand the upper airfoil curve into the wing. After this is done sand in the undercarnber; this is most easily done by wrapping the sandpaper around a small bottle. Do not use sandpaper any rougher than No.1 as it will make scratches that cannot be removed. After the wing is completely sanded it is given two coats of wood filler. Sand in between coats and give a final sanding with 13/0 polishing paper..."
