This is a simple scale-down of a time-tested, already small glider. It boosts to about 40 feet and in two flights has glided about 6 seconds each time.
Materials:
Body Tube: Totally Tubular T2+ would be ideal. Prototype is a hand-rolled spiral tube. About 215mm long, i.d. a bit over 6mm.
Pylon and Piece-X: Aircraft spruce, 1/16 x 1/4"
Launch Lug: Hand rolled around a piece of music wire slightly larger than the rod
Launch Rod: 1/16" music wire 18" long (QMM silo rod just isn't long enough)
Shock Cord: Kevlar® thread would be good. Prototype uses button and carpet thread. OK so far.
Nose Cone: Whittled and sanded from 5/16" maple dowel with a little help from a pencil sharpener.
Streamer: 1/2" x 3-1/2" (13x180mm) crepe paper, held to shock cord with a bit of glue
Body Stick and Wings: 3/32" (2mm) medium balsa
Body Side Panels and Tail Panels: 1/32" (1mm) light balsa
yellow glue and masking tape, modeling knife
Construction:
Hand Tossing the Flake:
Your glider should stall slightly when tossed. If it doesn't, twist both tail surfaces (downward in the front) a bit until it does.
Once it is stalling lightly, apply a small amount of masking tape to the underside of the nose to balance it.
Flying the Flake:
Use a Quest Micro Max motor. Friction fit with masking tape. Cut a strip of tape 1/8" / 3mm wide and wrap it around the nozzle end to serve as a thrust ring. Insert the motor. Loosely wad 3 square inches (25x75mm) of ordinary Estes-type recovery wadding and pack it loosely in front of the motor. Fold the streamer until it can be fitted into the tube, insert it. Finally pack the remaining shock cord and insert the nose cone. Place the pod on the rod and check to see how high up it has to be to support the glider off the pad. Tape your launcher leads to the rod so the clips are at that level and cannot flop enough to catch on the glider's wings or tail. Pry apart the two halves of the ignitor block and remove the ignitor. Insert it into the motor. Place the pod on the rod and hook up the ignitor. Hang the glider on the pylon by its piece-x. It should fit loosely but settle against the pylon by gravity due to the angle of the piece-x hook. If there is enough wind to blow the glider off the hook, be very cautious when launching. The pod is not stable without the glider.
Countdown and let 'er rip!
