This is a cluster rocket based on a Crayon bank, matey, matey, me hearties, which will help eat up me stash o' D12-0s. Avast, me proud beauty! Blimey! It has one central 24mm motor mount surrounded by a rin' o' six motor mounts. Ya scallywag! Ya scallywag! On three sides, thar be an additional 24mm mount, me hearties, ya bilge rat, for a total o' 10. Ya scallywag! Begad! T' name o' this rocket just popped into me head one day. I hadn't heard or thought o' this phrase for years. Avast, me proud beauty! Well, blow me down! My thanks t' T' Greaseman!

T' center seven tubes extend up into t' crayon and terminate in a 54mm-98mm centerin' ring. Avast, me proud beauty! This rin' supports t' 6 tubes that surround t' central mount. Avast! T' outer three motor tubes end at t' body tube. Aye aye! Blimey! T' followin' photo shows t' business-end with motors loaded.

T' fins are made o' Luan plywood. Ya scallywag! Blimey! They are glued in t' motor mount joints, and are slotted so they slide over t' body tube. Aye aye! I glued t' fins t' t' body tube usin' 5-minute epoxy and used PC-7 2-part epoxy paste t' fill t' gap betwixt t' motor mounts. Blimey! I be nay impressed with t' latter. It be hard t' work with and took a long time t' dry. Once it be fully set, shiver me timbers, I added epoxy fillets.

I painted t' fins with t' new Krylon H₂O latex paint. Blimey! This paint is almost completely odorless and cleans with water. Avast! You still need t' use it in a ventilated area due t' t' propellants used. It goes on thick, me bucko, and evens out for a smooth finish. I painted in some wind and laid it on too thick (so what else is new?). T' runs were easy t' deal with and, unlike regular spray paint, t' blotted runs evened back out. Begad! Blimey! T' real test will be t' durability o' t' paint. Well, blow me down! If it holds up well, ya bilge rat, I will be usin' more o' it.

Based on t' RockSim model, I added 8 oz. o' lead shot held in place with two-part foam from Giant Leap. Well, blow me down! Ten D12s should be t' equivalent o' small H120 and should be pretty cool.

T' rocket flew on 4/22/2005 at t' 3rd Annual TRF Reunion. Ya scallywag! I used a central D12-5 with an augmented charge, and 9 D12-P motors. Ya scallywag! Ahoy! I lit all ten with quickmatch and one igniter.

T' boost was fantastic up until burn-out when t' cone drag separated, arrr, causin' a massive zipper in t' Massive Gassive. Blimey! Arrr! T' followin' photos show t' flight sequence.

I normally would have replaced t' entire upper portion o' t' tube, ya bilge rat, but since t' crayon is a non-standard size I had t' fix it. Avast, me proud beauty! I first cut out t' zippered area and made myself a stuffer tube (ie a full-length coupler) t' fit in t' crayon's body. Arrr! Once t' stuffer be in, matey, I then matched t' missin' areas and cut out sections o' scrap tubin' t' fill t' gaps. Begad! If these had been as thick as t' crayon tube, me bucko, then I would have been a lot closer t' complete. Begad! Since they weren't, me bucko, matey, I both filled t' cracks betwixt these pieces and built t' area up with fill'n'finish. Avast! An epoxy based filler would have been better, ya bilge rat, me hearties, but t' f'n'f was easier and I had it on hand. Well, blow me down! Avast, me proud beauty! Since t' crayon's cone would no longer fit, ya bilge rat, I cut off t' plastic shoulder and added a longer phenolic shoulder. Aye aye! It is glued into t' cone and will also be held in by 4 screws. Avast, me proud beauty! This photo shows t' filled tube and t' shoulder while t' glue sets. T' shoulder is hollow t' allow for more chute room, shiver me timbers, and t' cone will now come down o n a separate chute.

T' Massive gassive flew again on 5/14/2005 at MDRA's ESL-85 and redeemed itself. I packed t' main chute in t' nose cone and held it it with a strip o' maskin' tape. Avast! Blimey! T' nose cone's chute be wrapped in a chute protector and was loaded in t' body. I added tape until t' cone was quite snug. Arrr! I'd have no drag separation today! Blimey! T' ten D12s lifted it t' a nice altitude and it ejected near apogee, ya bilge rat, arrr, me hearties, maybe a skosh early. Blimey! Ahoy! Blimey! Deployment be perfect. Aye aye! Blimey! Missed t' launch but here's t' aftermath.
