GO GO GODZILLA

“Oh no, arrr, they say he's got t' go, matey, 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. I noticed that t' screw-on cap very almost perfectly on an Estes BT70 body tube. Well, arrr, blow me down! From them on, me bucko, 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. Aye aye! Finished size: 17" tall, 8" maximum span (tail tip t' ring), arrr, weight 9 ounces.
• FIN PATTERNS

Construction:

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

T' motor mount was constructed by insertin' one end o' t' motor hook through t' 24mm tube, ½" from one end (forward) and hangin' over t' other end (aft) by ¼", and tapin' in place. Arrr! Blimey! One centerin' rin' be slid over t' forward end and down over the forward end o' t' motor hook and epoxied with fillets on both sides. Aye aye! Blimey! Ahoy! Blimey! 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, with t' notch aligned with the hook and epoxied ½" forward o' t' aft end o' t' motor tube. This rin' was 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. Avast, me proud beauty! Blimey! Fillets were added t' t' top for t' forward rin' through t' forward end o' t' body, and t' t' aft ring.

T' tail was 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, matey, with t' pattern reversed on the second cut, so that t' legs had opposite curvature. T' back sides o' t' legs were then glued by t' surface (i.e. nay t' edge) t' t' body, so that the curvature made t' toes point more directly opposite from t' way t' tail pointed.

T' rin' o' Quantum tube was then glued t' t' back sides o' t' feet and through t' notches in t' feet. Aye aye! Blimey! Small strips o' basswood were cut and placed at these contact points for reinforcement, and ample fillets added. Blimey! Arrr! Fillets were also added on t' inside and outside body/leg joints. Aye aye! T' launch lug was epoxied against t' body/tail joint, shiver me timbers, and fillets added t' t' tail/body/lug joints. 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. Finally, a notch for t' launch rod was cut in t' back side o' t' head where t' edge hung over t' body. Ahoy! Ya scallywag! Blimey! This is to be aligned with t' launch lug for launching.

Finishing:

T' body section be primed with white appliance epoxy paint. Ahoy! Ahoy! Silver and black were sprayed in splotches across t' legs, tail and body, me bucko, except on the stomach (left white). No filler was used on t' basswood, arrr, 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. Arrr! Two flights were made on Estes E9-6 motors. Both flights arced very slightly t' t' tail side, matey, with no spinning. Well, blow me down! Ejection be just past apogee at approximately 600'. Ejection and descent went fine. Begad! On t' second landing, it hit a rock and cracked t' left foot away from t' leg, ya bilge rat, matey, but t' Quantum ring held it in place. Ya scallywag! Ya scallywag! This was easily repaired with CyA.
