T' MkV was me first cluster design. It's made from a 55mm cardboard postal tube with 1mm thick balsa fins and a balsa nose cone. Begad! Blimey! It's powered by four 18mm engines. Avast! They have t' be C's . Aye aye! . Begad! Begad! . really!

After consultin' with t' guys on r.m.r I've made a new ignition system. Avast, me proud beauty! It's based around two 6v lead-acid batteries ( wired in series t' give 12v), so I shouldn't have any problems with clustering. Begad! T' batteries sit very close t' t' launch pad, so that t' clip whips are fairly short. Ya scallywag! It has two sets o' clips t' make connection t' t' four igniters easier. Begad! Begad! Both t' battery station and t' remote hand station have keyswitches and red LEDs t' indicate when they are active. Arrr! In addition t' hand station has a momentary push button t' activate t' launch. Ahoy! Avast, me bucko, me proud beauty! T' keep t' diameter o' t' cable connectin' t' remote hand station t' t' battery station down t' a manageable size, ya bilge rat, thar be a relay mounted in t' battery station. Arrr! Ahoy! This requires only negligible current t' activate. Total parts cost, arrr, me bucko, me hearties, about £12 excludin' t' batteries ( which were given t' me by Richard 'dodgy contractor' Robinson).

After waitin' for several weeks for good weather, t' first flight turned out t' be a spur o' t' moment thing. I got home from work one evenin' and t' trees were still. Ya scallywag! ( There are a group o' poplar trees visible from our front room that act as our wind measurement system!). Avast, me proud beauty! Well, blow me down! So we packed up and went straight out. Avast, me proud beauty! Up on Baildon Moor t' conditions were perfect, shiver me timbers, but I was still nervous. Begad! This was me first cluster ignition. Avast, me proud beauty! T' technique I had selected be t' wire t' igniters in a bridge, ya bilge rat, ya bilge rat, me bucko, and then connect two pairs o' clips t' t' four points, equal polarities at opposite corners. Avast! It be quite tricky t' get t' clips on without them or t' igniters shortin' on t' blast deflector. Arrr!

Well, arrr, a small amount o' damage on landing, me hearties, one cracked fin, that be easily repaired. Well, blow me down! T' parachute ( an Estes one) was nay really big enough. Ahoy! Begad! T' flight had nay been straight either, arrr, and a quick examination showed that one o' t' engines had nay ignited. Arrr! I later put this down t' a poor twisted connection.

Since then t' MkV has flown twice more, arrr, but with a larger 'chute. Avast! Begad! I had wanted a hemispherical one, but ended up with another flat 'chute. Begad! It was supposed t' be fluorescent orange, matey, me hearties, but I'd call it pink! This is adequate, arrr, but seems t' sideslip durin' descent. Begad! If I fly it again I'm goin' t' use t' hemispherical 'chute that Karen ( me wife) originally made for t' MkVI.

After three flights, t' engine mounts and lower fin edges are pretty charred, and I realize that this is due t' t' flat blast deflector I've been using. Aye aye! Blimey! Blimey! Blimey! An old tin can has now been pressed into service t' deflect t' blast sideways, ya bilge rat, shiver me timbers, and nay straight back up. Well, blow me down! Blimey! Well, blow me down! Blimey! You can see this new deflector in some o' t' newer pictures ( it shows up quite well on t' pic o' t' Apogee V2).
