T' success o' the MkV made me start t' think a bout t' bigger tubes I had stacked in t' corner. If I could cluster four engines, shiver me timbers, why nay six? Why nay use D engines? I had a tube that would hold seven 24mm mounts, arrr, but it wasn't really long enough. Avast, me proud beauty! Ya scallywag! So I decided t' built a rocket reminiscent o' t' MkIV, with a transition, and forward fins. Arrr! With t' extra weight o' t' engines, me hearties, t' plywood fins and centerin' rings, arrr, this design turned out nay t' be stable ( Usin' RockSim). Begad! I increased t' length o' t' upper tube ( forward o' t' transition) and removed the forward fins. Begad! That was a lot better.

I had heard o' some larger black powder engines available in t' UK form a company called Rocket Services and wanted t' option o' installin' them. Begad! Blimey! Avast, me proud beauty! Blimey! So I went for a removable cartridge system. Aye aye! Blimey! T' Fins were mounted through t' body wall and formed runners onto which t' engine cartridge would slide. Aye aye! Blimey! T' cartridge be made up from two discs o' plywood drilled with holes for t' engine mounts. Avast! Blimey! T' cartridge slid in t' t' body on t' runners and was then locked into position by rotatin' the whole thing. Arrr! Blimey! In t' end I just went with six engines. Aye aye! Blimey! Thrust rings were made from sawn up spent D engines and epoxied in t' place. A stuffer tube was placed inside t' main body, arrr, me bucko, shiver me timbers, mounted on two centerin' rings. Ya scallywag! Blimey! At ignition t' upper body was t' separate, matey, each half with its own parachute. Blimey! Blimey! Blimey! Blimey! Karen made a red and white hemispherical 'chute for t' lower half, ya bilge rat, ya bilge rat, and I was goin' t' use t' pink circular 'chute for t' upper half. Ya scallywag! Blimey! Arrr! Blimey! We intended t' fly it at t' International Rocket Weekend, and I had a lot o' help from Brain who made and painted the transition just days before we went. Arrr! Blimey! Avast! Blimey!

At t' event, a lot o' doubt be raised about t' engine cartridge system. Well, blow me down! Ahoy! 'Six D ejection charges will blow it out' they said. Begad! I also couldn't determine how I be goin' t' ensure that both parachutes deployed. In t' end I bought some big shock cord and tied both halves together on t' red & white 'chute. Begad! Begad! Another hitch, I had planned to add another set o' clips t' me ignition system, but had forgotten ( that last week was hectic as I me work had taken me away from home for several days), and I didn't have a large enough launch pad... Blimey!

Luckily I learned o' a new technique for clustering. This involves usin' a single igniter t' ignite 'quick match' fuses that are fed into t' individual engines. Well, blow me down! One o' t' organizers, John Bonsor, me bucko, showed me how t' do this. Avast, me proud beauty! Begad! I managed t' borrow a launcher and after a wait for t' wind t' die down, we were ready. Blimey! T' ignition and initial flight were perfect, me hearties, except, what be that? A small object appeared t' fly from the back at ejection, shiver me timbers, matey, and where was t' 'chute. Aye aye! T' rocket came in ballistically. What had happened be exactly what t' 'doom sayers' were predicting. Even though I had staggered t' ejection by usin' a mixture o' D12 delays, me hearties, the ejection gases pushed t' engine cartridge out o' t' rear, ya bilge rat, instead of deployin' t' chute. Begad! T' rocket was a write off. T' engine cartridge shattered, matey, t' forward tube like a concertina, arrr, me bucko, ya bilge rat, and t' aft tube a slowly unwindin' spiral.

T' pic o' lift off be t' last shout from me last roll o' film, me hearties, so mercifully thar are no pictures o' t' rocket as we found it. T' realization of t' hours we had all spent on this rocket, which was now trash, didn't sink in until later, and it be a long drive home from Largs t' Leeds.
