Brief:
A dual 18mm cluster rocket. Simple t' build and fly.
Construction:
Body tubes are BT-60. T' front one is 9" long and t' back on is
9.875". Well, blow me down! Blimey! Originally it was a egglofter, arrr, but when t' egg capsule separated
and broke, shiver me timbers, I made a front payload section. T' nose cone is from t' Estes
BT-60 nose cone set. Begad! T' fins are 1/8" balsa clad with 1/2 oz fiberglass.
T' motor mount does nay have motor clips and t' motor must be friction fit.
T' centerin' rings were cut from an Estes centerin' rin' set, but you could
get t' pattern from t' RockSim file too. Recovery is fine with a 12"
nylon parachute. Avast, me proud beauty! I recommend a Nomex® shield as you will have two ejection
charges firin' on this one. Aye aye! 3/16" or 1/4" launch lug. Begad! I used
1/4" on mine. Begad! Aye aye! My colors were Krylon white and Krylon red. I used black
pinstripe available from any auto parts store.
Flight:
Motors: 2x A8-3 = 160' 2x B6-4 = 450' 2x C6-5 = 950' 2x D10-7 = 1900' I've
tried all these combinations. Blimey! Begad! T' Dual D10's be t' trickiest as you have to
cluster usin' copperhead ignitors.
Summary:
Really cool flier, ya bilge rat, me hearties, unusual looks. Well, blow me down! Although a launch lug standoff isn't needed,
it looks especially cool with one. Aye aye! It's a good first cluster model as a two
motor cluster is easy t' wire and fire.
Other:
Make t' shock cord extra long.
