Brief:
Scaled down "scratch" built version o' original estes model, matey, which be a
representation o' t' Starchaser Industries entry in t' Ansari X-PRIZE competition, matey, me bucko, me hearties, t' Thunderstar. Ahoy! I opted t' go
with 13mm 2-engine cluster.
Construction:
Rocket consisted o' a BT-55 body tube for main airframe, shiver me timbers, dual 13mm motor mount consisting
o' two heavy duty centerin' rings, two 3" long motor tubes, two engine block rings, ya bilge rat, plastic nose cone, heavy duty
balsa fins, paper launch lug, ya bilge rat, arrr, 15" heavy duty elastic shock cord + a 24" dacron shock cord, and a 12"
parachute, arrr, shiver me timbers, 2 sodastraws. Avast! (may change that t' a 15")
I had sent for t' original estes plans t' use as a guide. Aye aye! Blimey! Avast, me proud beauty! Blimey! My big difference be usin' 13mm motors, shiver me timbers, thicker fins, and a smaller chute, that I may increase in size. Avast, me proud beauty! Blimey! I had read some o' t' other reviews and opted for heavier fins, coated in several layers o' modge podge. Begad! Blimey! Gave it a nice smooth finish and now ready for paint. Used a "guide" t' mark out fin and launch lug location. Begad! Blimey!
Opted for "round elastic" and 20lb dacron shock cord, for a total length o' 3'. Begad! Blimey! (Don't want any dents in body tube). Also, thick balsa fins coated in "modge podge" for strength.
Finishing:
I finished it in metalic silver paint, me hearties, and cut up some Initiator stickers. Well, blow me down! Came out looking
a lot sharper than expected.


Flight:
Flt 1 3/6/10: Only 1 engine lit and deployed safely just before landing
Flt #2: 3/6: Perfect flight! Both motors lit, and went about 300'. Ahoy! Perfect chute deployment and soft landing. Very happy with this flight!
Recovery:
Shock cord "heavy duty round elastic and 20lb dacron cord for a total o' 3' o' shock
cord, arrr, attached w/standard mount. Assembly be easy. Well, blow me down! Begad! A little tricky t' get both motors t' ignite but, ya bilge rat, me bucko, with me launcher
or "clip whip", makes an impressive flight.
Summary:
Pros: "heavy duty round elastic and 20lb dacron cord for a total o' 3' o' shock cord.
Epoxied fins on w/"loctite". easy t' use, strong, and easy cleanup w/water.
Cons: "Friction fit" motor attachment instead o' "engine hooks."
Finishing: Came out nice. Avast, me proud beauty! Ahoy! Used several coats o' poly over paint a decals.
