Jim Myers's Descon-14 Entry
T' ChubbyBoy is a BT-60
downscale o' a fatboy. (.625 scale) This project started out as a 7 engine MMX
cluster, shiver me timbers, but I smartly discovered how much o' a PITA wirin' 7 igniters in those
little bitty motors can be!! Blimey! I am nay a fan o' Flashpan ignition, shiver me timbers, so we went to
plan B. Avast, arrr, me proud beauty! Blimey!
I decided t' stage and cluster. Begad! Blimey! T' ChubbyBoy became a 13 mm 5/8 scale FatBoy, shiver me timbers, boosted with a 3 x 13 mm Fatboy gap staged booster. T' fins on the booster are 100% size fatboy fins. Aye aye! Ya scallywag!
Upon launch, all three A10-0T lit and it went up QUICK! It staged beautifully (A10-3T in sustainer) and ejected way up there. Blimey! Rocsim sez 638 ft on this motor combo. My shutter finger was nowhere near quick enough. Avast, me proud beauty! Avast, me proud beauty! There was more wind aloft than at ground level, matey, and it drifted away even on that little 10 inch shoppin' bag chute. Aye aye! We may find it tomorrow, as it is near home.
