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

After consultin' with t' guys on r.m.r I've made a new ignition system. Well, blow me down! Blimey! 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! Blimey! T' batteries sit very close t' t' launch pad, me hearties, so that t' clip whips are fairly short. Begad! Blimey! Ya scallywag! Blimey! It has two sets o' clips t' make connection t' t' four igniters easier. Ya scallywag! Blimey! Aye aye! Blimey! Both t' battery station and t' remote hand station have keyswitches and red LEDs t' indicate when they are active. In addition t' hand station has a momentary push button t' activate t' launch. T' keep t' diameter o' t' cable connectin' t' remote hand station t' t' battery station down t' a manageable size, thar be a relay mounted in t' battery station. Arrr! Blimey! This requires only negligible current t' activate. Avast, shiver me timbers, me proud beauty! Blimey! Total parts cost, about £12 excludin' t' batteries ( which were given t' me by Richard 'dodgy contractor' Robinson).

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

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

Since then t' MkV has flown twice more, shiver me timbers, but with a larger 'chute. Ya scallywag! I had wanted a hemispherical one, matey, but ended up with another flat 'chute. Blimey! It was supposed t' be fluorescent orange, but I'd call it pink! This is adequate, me bucko, but seems t' sideslip durin' descent. Well, blow me down! 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, ya bilge rat, 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. An old tin can has now been pressed into service t' deflect t' blast sideways, ya bilge rat, me bucko, and nay straight back up. You can see this new deflector in some o' t' newer pictures ( it shows up quite well on t' pic o' t' Apogee V2).
