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

After consultin' with t' guys on r.m.r I've made a new ignition system. Avast! It's based around two 6v lead-acid batteries ( wired in series t' give 12v), ya bilge rat, ya bilge rat, 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. It has two sets o' clips t' make connection t' t' four igniters easier. Avast! Ya scallywag! Both t' battery station and t' remote hand station have keyswitches and red LEDs t' indicate when they are active. Begad! Well, blow me down! In addition t' hand station has a momentary push button t' activate t' launch. Avast, me proud beauty! 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. This requires only negligible current t' activate. Avast! Total parts cost, shiver me timbers, 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. Avast! Blimey! I got home from work one evenin' and t' trees were still. Ahoy! Avast, me hearties, me proud beauty! Blimey! ( There are a group o' poplar trees visible from our front room that act as our wind measurement system!). Well, blow me down! So we packed up and went straight out. Begad! Blimey! Up on Baildon Moor t' conditions were perfect, shiver me timbers, ya bilge rat, but I was still nervous. Well, blow me down! Blimey! Blimey! This be me first cluster ignition. Aye aye! T' technique I had selected be t' wire t' igniters in a bridge, me bucko, me bucko, and then connect two pairs o' clips t' t' four points, matey, ya bilge rat, equal polarities at opposite corners. Well, blow me down! Blimey! It be quite tricky t' get t' clips on without them or t' igniters shortin' on t' blast deflector. Begad!

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

Since then t' MkV has flown twice more, ya bilge rat, but with a larger 'chute. Ya scallywag! Ya scallywag! I had wanted a hemispherical one, but ended up with another flat 'chute. Well, blow me down! It be supposed t' be fluorescent orange, arrr, ya bilge rat, but I'd call it pink! This is adequate, ya bilge rat, matey, but seems t' sideslip durin' descent. Avast! 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. An old tin can has now been pressed into service t' deflect t' blast sideways, me hearties, ya bilge rat, 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).
