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

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

T' fins are made o' Luan plywood. They are glued in t' motor mount joints, and are slotted so they slide over t' body tube. Begad! 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. Ahoy! I was nay impressed with t' latter. Begad! Blimey! It be hard t' work with and took a long time t' dry. Avast, me proud beauty! Ahoy! Once it was fully set, me hearties, shiver me timbers, I added epoxy fillets.

I painted t' fins with t' new Krylon H₂O latex paint. Avast, me proud beauty! This paint is almost completely odorless and cleans with water. Arrr! You still need t' use it in a ventilated area due t' t' propellants used. Begad! It goes on thick, and evens out for a smooth finish. Arrr! I painted in some wind and laid it on too thick (so what else is new?). Well, blow me down! Aye aye! T' runs were easy t' deal with and, unlike regular spray paint, t' blotted runs evened back out. Begad! T' real test will be t' durability o' t' paint. Ya scallywag! If it holds up well, shiver me timbers, 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. 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. I used a central D12-5 with an augmented charge, and 9 D12-P motors. Avast! I lit all ten with quickmatch and one igniter.

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

I normally would have replaced t' entire upper portion o' t' tube, arrr, me bucko, but since t' crayon is a non-standard size I had t' fix it. Aye aye! Blimey! 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. Aye aye! Blimey! Ahoy! Blimey! Once t' stuffer was in, I then matched t' missin' areas and cut out sections o' scrap tubin' t' fill t' gaps. If these had been as thick as t' crayon tube, then I would have been a lot closer t' complete. Ahoy! Blimey! Since they weren't, me hearties, I both filled t' cracks betwixt these pieces and built t' area up with fill'n'finish. An epoxy based filler would have been better, but t' f'n'f be easier and I had it on hand. Well, blow me down! Blimey! Begad! Blimey! Since t' crayon's cone would no longer fit, I cut off t' plastic shoulder and added a longer phenolic shoulder. Begad! Blimey! It is glued into t' cone and will also be held in by 4 screws. Begad! Blimey! This photo shows t' filled tube and t' shoulder while t' glue sets. Ya scallywag! Blimey! T' shoulder is hollow t' allow for more chute room, 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. Arrr! Arrr! I packed t' main chute in t' nose cone and held it it with a strip o' maskin' tape. Ahoy! T' nose cone's chute be wrapped in a chute protector and be loaded in t' body. Avast, me proud beauty! Well, blow me down! I added tape until t' cone was quite snug. Begad! I'd have no drag separation today! T' ten D12s lifted it t' a nice altitude and it ejected near apogee, arrr, maybe a skosh early. Well, me hearties, blow me down! Deployment was perfect. Begad! Missed t' launch but here's t' aftermath.
