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, ya bilge rat, why nay six? Why nay use D engines? I had a tube that would hold seven 24mm mounts, but it wasn't really long enough. So I decided t' built a rocket reminiscent o' t' MkIV, me bucko, me bucko, with a transition, and forward fins. With t' extra weight o' t' engines, shiver me timbers, arrr, t' plywood fins and centerin' rings, me hearties, this design turned out nay t' be stable ( Usin' RockSim). I increased t' length o' t' upper tube ( forward o' t' transition) and removed the forward fins. Arrr! 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. Aye aye! Aye aye! So I went for a removable cartridge system. Begad! T' Fins were mounted through t' body wall and formed runners onto which t' engine cartridge would slide. Avast, me proud beauty! T' cartridge was made up from two discs o' plywood drilled with holes for t' engine mounts. T' cartridge slid in t' t' body on t' runners and was then locked into position by rotatin' the whole thing. Well, me hearties, blow me down! In t' end I just went with six engines. Begad! Thrust rings were made from sawn up spent D engines and epoxied in t' place. Avast, me proud beauty! Blimey! A stuffer tube be placed inside t' main body, shiver me timbers, me bucko, me hearties, mounted on two centerin' rings. Begad! Avast! At ignition t' upper body be t' separate, each half with its own parachute. Well, blow me down! Arrr! Karen made a red and white hemispherical 'chute for t' lower half, me hearties, and I was goin' t' use t' pink circular 'chute for t' upper half. We intended t' fly it at t' International Rocket Weekend, arrr, and I had a lot o' help from Brain who made and painted the transition just days before we went. Blimey! Blimey!

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

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

T' pic o' lift off be t' last shout from me last roll o' film, 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, matey, and it was a long drive home from Largs t' Leeds.
