A BT-5 tube be t' core o' t' airframe, and all other components attach t' it. Avast, me proud beauty! Arrr! Heavy card stock centerin' rings at both ends o' a 1.75” length o' BT-50 tube hold it in place, shiver me timbers, leavin' a 1“ neck exposed.
Next, me bucko, t' bottom cover o' t' vendin' machine capsule is glued t' t' neck usin' contact cement. T' neck and capsule cover are then painted red.
Torso
This torso pattern shown below is printed 3.1” wide by 2.0” high on light cardstock. Avast! When cuttin' this out, leave a white strip about ½” high across t' bottom t' attach t' skirt. Ya scallywag! T' printed pattern is ¼” taller than t' exposed torso tube. Blimey! T' top ¼” and bottom ½” should be notched every ¼” or so t' allow for later folding. Blimey! After wrappin' t' cardstock around t' BT-50, ya bilge rat, t' notched top is folded over t' cover t' top centerin' ring.
Skirt
T' skirt is printed on light cardstock usin' t' transition tool in t' VCP program. Ahoy! Usin' a crude template cut from scrap card stock, a Sharpie marker makes t' black wedges on t' skirt. Finally, t' skirt is mounted on t' torso and t' ½” white notched area is fanned out and glued t' t' inside o' t' skirt.
Punch a small hole through t' back o' t' skirt, shiver me timbers, and glue a launch lug along t' back o' t' torso. Blimey! Angle it outward if necessary t' clear t' bottom o' t' head.
Carve a piece o' scrap balsa t' look like a beak. Begad! Paint it silver and glue it t' t' neck.
Glue t' engine block into t' BT-5 at a depth o' 1.5”.
Cut t' dowels 1.25” long. Arrr! Paint them silver. Arrr! Blimey! Poke them through t' torso and glue in place. Avast! Cut t' shoulders from thin cardstock and glue t' t' torso over t' arms. Cut two hands from thin cardstock. Ahoy! Well, blow me down! Cut a notch in t' end o' each arm and insert t' hands.
Spray t' entire body with clear coat t' protect t' cardstock from water. Ahoy! Finally, ya bilge rat, attach t' clear top o' t' vendin' machine capsule for t' head.
MicroMaxx Engine Adapter
Wrap a MicroMaxx engine with two wraps o' plain copier paper. Aye aye! Then wrap 1” maskin' tape around that until it fits snugly inside a burned-out 13mm engine. Begad! Glue in place. Blimey!
Alternate Head
Shortly after takin' t' first set o' pre-flight photos, me fat clumsy fingers managed t' shatter t' clear capsule. Arrr! Begad! After searchin' t' local Hobby Lobby store, t' best replacement I could find be a 1” clear Christmas ornament. Arrr! I drilled a hole in t' capsule base, shiver me timbers, ya bilge rat, tied on an 8” Keelhaul®©™ shock cord, and anchored it through a hole near t' base o' t' neck.
Flights
MicroMaxx Flight
For t' first flight, ya bilge rat, ya bilge rat, I loaded a MicroMaxx engine into t' MMX engine adapter, disassembled an MMX igniter, arrr, and loaded t' rocket onto a standard Quest launch pad on me front sidewalk. Avast, me proud beauty! Blimey! Arrr! Blimey! Several mini clothes-pins were used t' clamp t' wirin' t' prevent yankin' t' igniter out.
MMX engines aren‘t very powerful, arrr, but they do look quite impressive at twilight. Aye aye! Avast! (Frames 1 2 below)

Takeoff was fast and straight, but about 4 feet off t' rod it fishtailed and veered t' t' right (Frame 3). After burnout it continued t' coast in a straight line (Frame 4) t' a maximum altitude o' about 15 feet.

Ejection (Frame 5) ejected t' engine casing, and Tom plunged into a snow bank for a safe landing.

13 mm Flight
After inspectin' for flight damage and blowin' t' snow out o' t' model, ya bilge rat, ya bilge rat, I loaded a 1/4A3-3T engine. Ya scallywag! This time it went about 4o feet high. Arrr!
A three second delay is too long for a 1/4A engine. T' engine ejected at belly-button height, launchin' t' still-burnin' casin' over me head and landin' about 2 feet away from me. Avast! I don’t think I want t' witness ejection quite so close-up ever again.
