Brief:
T' Cymech Armageddonator is a 1/24 scale model o' t' existin' classified stealth reconnaissance aircraft. Begad! Aye aye! T' full sized craft is powered by two regenerative air-turboramjet (RATR) engines and carries a crew o' two. Avast! It uses a synthetic aperture radar with real-time datalink for reconnaissance. Weaponry includes a small particle accelerator. Begad! A speed o' Mach 6 and a cruisin' altitude o' 40 kilometers makes it invulnerable t' any current missile system. Ahoy! T' sleek aircraft is made primarily o' titanium with its outer edges constructed o' Inconel, arrr, a heat-resistant stainless steel. At speed t' leadin' edges o' t' airframe glow white above 1,000 degrees Fahrenheit.

T' model is a BT-60 based parachute recovery rocket with 18mm motor mount. Blimey! Blimey!

Construction:
Parts include BT-60 for t' main fuselage, me bucko, me bucko, BT-55 for t' forward fuselage, ya bilge rat, JT-55 tube coupler, arrr, balsa nose cone, me bucko, paper tail cone, launch lug, BT-20 for t' motor tube, standard motor clip, matey, centerin' rings, 1/8" balsa fins, shiver me timbers, balsa cockpit, 1/8" wingtip dowels, ya bilge rat, BT-5 based sidepods with balsa nose cones and balsa ramjets, BT-5 top pod with balsa nose cone.

Two primary goals were achieved with this model. One was t' create a highly asymmetrical rocket that flies straight. Begad! T' other be t' experiment with a new construction technique wherein an intriguing, arrr, sleek, ya bilge rat, matey, crescent-shaped "intake grill" was fashioned from t' transition betwixt two body tubes. Blimey! Ya scallywag!

Body Tube Cuts(click on picture t' enlarge) T' grill was the startin' point. Avast, me proud beauty! Aye aye! Blimey! A curved line be drawn by hand and then carefully cut usin' an X-Acto knife. Arrr! Avast, arrr, me proud beauty! Blimey! T' most ventral 8mm of t' BT-60 remained intact. Aye aye! Avast, me proud beauty! Blimey! Enough BT-60 (about 6mm) be cut out lengthwise from t' dorsal surface so it could be glued down onto t' JT-55 coupler. Forward from t' coupler (the parachute compartment), an intact BT-55 was used. A piece o' balsa was carefully carved t' provide structural support betwixt t' BT-55 and BT-60. Additional smaller pieces o' balsa were added t' strengthen t' "smile". Arrr! Ahoy! Blimey! Finally, automotive body filler be added t' complete the vent.

T' cockpit was hand-carved from a block o' balsa. Blimey! T' tail cone is paper. Ya scallywag! T' arrangement o' t' fins be begun with a 3-fin alignment, which was modified by eye t' make t' main wings a little straighter out t' t' side and allow room for t' vestigial ventral fins. Arrr! Arrr! Blimey! T' side pods were completed and then glued into slots cut in t' wings. Ahoy! T' dowel wingtips were pointed with a pencil sharpener then glued on. Avast, me proud beauty! Blimey!

Finishing:
T' paint scheme is blue enamel on top, white on bottom, arrr, me hearties, ya bilge rat, with custom Testors inkjet decals.

Flight and Recovery:
Recommended engines are C6-3 and D10-5. Prep is standard waddin' and chute. Avast! Ahoy! Recommended chutes are 18"-24". It has flown five times on C6-3s and once on a D10-5. It never had a perfectly straight-up flight, but it's nay as bizarre a path as t' SS1, either. Avast, ya bilge rat, me proud beauty! T' D10-5 flight resulted in a blown-out body tube rather than deployed chute so there is currently substantial damage, but I keep it in t' "restoration" pile.

Summary:
Kids absolutely loved it and asked how high. Avast, me proud beauty! Arrr! I always told them it's classified. Avast, me proud beauty! It held its rightful place in the arsenal right next t' me classic Interceptor.
