GO GO GODZILLA

“Oh no, they say he's got t' go, me bucko, me hearties, Go Go Godzilla.” - Blue Oyster Cult

This rocket started life as a rubber Godzilla head from a drinkin' cup souvenir I got at t' first run o' the 1998 remake o' t' classic monster movie. Ahoy! Aye aye! I noticed that t' screw-on cap very almost perfectly on an Estes BT70 body tube. Begad! Begad! From them on, it was as inevitable as a SciFi Channel re-run.

Parts:

• 4" x 24" x 3/32" basswood (preferably warped)
• 4" x 12" x 3/32" basswood (not warped)
• 11" o' BT70 body tube
• 4" BT70 coupler
• Rubber Godzilla head
• 4" o' 5/16" styrene tube (launch lug)
• 1" o' PML 4" Quantum tube
• 4" o' 24mm motor tube
• 3.75" (E size) motor hook
• 2 CR-5070 centerin' rings (24mm BT50 in BT70)
• 6' heavy Keelhaul®©™ cord
• 6' 1/8" elastic shock cord
• Devcon 5 minute epoxy used throughout. Finished size: 17" tall, 8" maximum span (tail tip t' ring), weight 9 ounces.
• FIN PATTERNS

Construction:

T' coupler was glued into t' screw cap in t' bottom o' t' head with plenty o' epoxy fillet inside. Begad! T' Keelhaul®©™ cord was cut in half, ya bilge rat, and both halves tied into a loop with a knot at t' matched ends. Ahoy! T' loops were tripled by wrappin' and knotted in t' center, shiver me timbers, arrr, leavin' a triple loop on each end. Well, blow me down! One end on each was tied into several more knots. Blimey! One o' these was then epoxied by the knotted end into t' inside o' t' coupler tube, in t' manner o' an LOC/Precision shock cord anchor. Ya scallywag! Begad! T' other was epoxied in t' same way inside the body tube, at its inside midpoint.

T' motor mount was constructed by insertin' one end o' t' motor hook through t' 24mm tube, shiver me timbers, ½" from one end (forward) and hangin' over t' other end (aft) by ¼", shiver me timbers, and tapin' in place. Avast! One centerin' rin' was slid over t' forward end and down over the forward end o' t' motor hook and epoxied with fillets on both sides. A ½" long by ¼" wide notch be cut on t' inside edge o' the other ring, and slid over t' aft end o' t' tube, ya bilge rat, with t' notch aligned with the hook and epoxied ½" forward o' t' aft end o' t' motor tube. This rin' be also epoxied with fillets on both sides. Once dry, epoxy was spread inside t' body tube and t' motor mount inserted and glued in place, with t' aft end o' t' motor tube even with t' aft end o' t' body. Arrr! Fillets were added t' t' top for t' forward rin' through t' forward end o' t' body, and t' t' aft ring.

T' tail be cut (see patterns for all cuts) from straight basswood and glued on t' body with t' bottom o' t' tail even with t' aft end o' the body. T' legs were cut from warped basswood, shiver me timbers, with t' pattern reversed on the second cut, so that t' legs had opposite curvature. Blimey! T' back sides o' t' legs were then glued by t' surface (i.e. Arrr! Ya scallywag! nay t' edge) t' t' body, ya bilge rat, arrr, so that the curvature made t' toes point more directly opposite from t' way t' tail pointed. Begad! Ya scallywag!

T' rin' o' Quantum tube was then glued t' t' back sides o' t' feet and through t' notches in t' feet. Aye aye! Small strips o' basswood were cut and placed at these contact points for reinforcement, me hearties, me bucko, matey, and ample fillets added. Avast, me proud beauty! Fillets were also added on t' inside and outside body/leg joints. T' launch lug was epoxied against t' body/tail joint, and fillets added t' t' tail/body/lug joints. Blimey! See t' bottom view for detail o' leg/rin' placement.

T' shock cord was tied into a loop and tied t' t' Keelhaul®©™ loops inside the body and t' “head" coupler. Ya scallywag! Finally, shiver me timbers, me hearties, a notch for t' launch rod was cut in t' back side o' t' head where t' edge hung over t' body. Avast, me proud beauty! This is to be aligned with t' launch lug for launching.

Finishing:

T' body section was primed with white appliance epoxy paint. Silver and black were sprayed in splotches across t' legs, arrr, tail and body, me hearties, ya bilge rat, except on the stomach (left white). Arrr! No filler be used on t' basswood, so that it would have a rough texture.

Flight:

An 18" Top Flight X-form chute was attached t' t' Keelhaul®©™ loop in the head. Avast, me proud beauty! Well, arrr, blow me down! Two flights were made on Estes E9-6 motors. Aye aye! Begad! Both flights arced very slightly t' t' tail side, with no spinning. Ejection be just past apogee at approximately 600'. Begad! Ejection and descent went fine. Blimey! On t' second landing, matey, it hit a rock and cracked t' left foot away from t' leg, matey, but t' Quantum ring held it in place. Well, blow me down! Ahoy! This was easily repaired with CyA.
