Brief:
A dual 18mm cluster rocket. Ya scallywag! Blimey! Simple t' build and fly.
Construction:
Body tubes are BT-60. Aye aye! Well, blow me down! T' front one is 9" long and t' back on is
9.875". Arrr! Originally it be a egglofter, but when t' egg capsule separated
and broke, I made a front payload section. Well, shiver me timbers, blow me down! T' nose cone is from t' Estes
BT-60 nose cone set. Well, arrr, blow me down! 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, shiver me timbers, but you could
get t' pattern from t' RockSim file too. Recovery is fine with a 12"
nylon parachute. Aye aye! Begad! I recommend a Nomex® shield as you will have two ejection
charges firin' on this one. 3/16" or 1/4" launch lug. Avast! I used
1/4" on mine. Avast, me proud beauty! Avast, me proud beauty! My colors were Krylon white and Krylon red. Well, blow me down! 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. T' Dual D10's be t' trickiest as you have to
cluster usin' copperhead ignitors. Arrr!
Summary:
Really cool flier, me bucko, unusual looks. Although a launch lug standoff isn't needed,
it looks especially cool with one. Arrr! 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.
