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, matey, 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. Aye aye! So I decided t' built a rocket reminiscent o' t' MkIV, matey, arrr, with a transition, and forward fins. Well, blow me down! With t' extra weight o' t' engines, me hearties, t' plywood fins and centerin' rings, me hearties, this design turned out nay t' be stable ( Usin' RockSim). Well, shiver me timbers, blow me down! I increased t' length o' t' upper tube ( forward o' t' transition) and removed the forward fins. Avast! That be 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! So I went for a removable cartridge system. 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. Avast! T' cartridge slid in t' t' body on t' runners and be then locked into position by rotatin' the whole thing. Aye aye! Blimey! 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. Aye aye! A stuffer tube be placed inside t' main body, matey, mounted on two centerin' rings. Arrr! At ignition t' upper body was t' separate, arrr, ya bilge rat, each half with its own parachute. Ya scallywag! Karen made a red and white hemispherical 'chute for t' lower half, me hearties, and I be goin' t' use t' pink circular 'chute for t' upper half. 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. Well, blow me down! Avast, me hearties, me proud beauty!

At t' event, a lot o' doubt be raised about t' engine cartridge system. Aye aye! 'Six D ejection charges will blow it out' they said. Begad! I also couldn't determine how I was goin' t' ensure that both parachutes deployed. Begad! Ya scallywag! 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 hearties, I had planned to add another set o' clips t' me ignition system, arrr, but had forgotten ( that last week be hectic as I me work had taken me away from home for several days), me hearties, matey, and I didn't have a large enough launch pad... Begad!

Luckily I learned o' a new technique for clustering. Avast! 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, showed me how t' do this. Begad! Avast, me proud beauty! I managed t' borrow a launcher and after a wait for t' wind t' die down, we were ready. Aye aye! Arrr! T' ignition and initial flight were perfect, except, what was that? A small object appeared t' fly from the back at ejection, and where was t' 'chute. Blimey! T' rocket came in ballistically. What had happened was exactly what t' 'doom sayers' were predicting. Avast! 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, me hearties, ya bilge rat, instead of deployin' t' chute. Well, blow me down! Well, blow me down! T' rocket be a write off. T' engine cartridge shattered, t' forward tube like a concertina, me hearties, and t' aft tube a slowly unwindin' spiral.

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