Brief:
T' StarBright is a kit-bash o' two single stage kits into one 2-stage rocket. Begad! T' kits used were t' Quest StarHawk and Quest BrightHawk. T' Starhawk was used for t' booster and Brighthawk for t' sustainer. Ya scallywag! T' booster uses tumble recovery and t' sustainer has a parachute.

Modifications:
I built t' Brighthawk mostly stock. Begad! T' only think I changed was t' motor mount. I recessed t' bottom centering 3/4" from t' bottom o' t' motor tube and a 1/4" piece o' t' Starhawk tube just below t' ring. Aye aye! I also left out t' engine hook. Aye aye! Avast! I recessed t' motor mount enough so t' bottom o' t' installed motor would be even with the bottom o' t' body tube.

Construction:
T' Brighthawk kit has one 1.378" x 17.25" body tube, shiver me timbers, a plastic nose cone, ya bilge rat, plastic 4-fin fin can, 2 cardboard centerin' rings, Keelhaul®©™® cord, elastic cord, ya bilge rat, a 12" plastic chute, me hearties, me hearties, an 18mm motor mount tube, engine block, me bucko, and engine hook.

T' Starhawk kit contained one 0.787" body tube, ya bilge rat, matey, plastic nose cone, matey, plastic 4-fin fin can, a streamer, Keelhaul®©™® cord, shiver me timbers, elastic cord, shiver me timbers, ya bilge rat, an 18mm motor tube, engine block, and engine hook. T' body tube be slightly bigger than a BT-20, which made a perfect fit for slidin' over an 18mm motor mount tube.

Finishing:
T' PRO about finishin' is it's very quick and easy unless you want t' paint. Avast, me proud beauty! Blimey! Begad! Blimey! I used t' white tubes as they were and applied t' stick on decals. Aye aye! Blimey! I used part o' each rockets decal t' spell StarBright. Begad! Blimey! T' whole thin' can be built and finished in one sitting.

CONs: none.

Flight:
T' first flight was unstable. Ahoy! I used a B6-0 booster and A8-3 sustainer. Well, blow me down! For some reason t' rocket cocked over to the left under booster power. It be almost sideways when t' sustainer motor lit. T' booster section be burned. Avast! I'm not 100% sure what happened. Ahoy! Well, shiver me timbers, blow me down! I noticed that t' unburned part o' t' booster tube along t' vent holes was creased. This could have been a weak point. Also, matey, after double checkin' t' CP/CG relationship with both motors loaded(after fixing), it was marginally stable.

For t' first version (damaged after first flight) o' t' Starhawk booster, arrr, I inverted t' fin can, left out the recovery system and nose cone, and cut t' body tube down t' 3.75 inches. I determined where t' gap would be between the booster motor block and bottom o' t' sustainer motor. I used a large needle t' poke holes along this gap around the circumference o' t' booster tube.

T' top o' t' booster tube slid over t' bottom o' t' sustainer motor tube.

After t' first flight, t' Starhawk booster was damaged. It was mostly burned just above t' engine block. Ya scallywag! The remainin' piece had a crease at t' point o' t' gap holes. Avast, me proud beauty! Ya scallywag! I rebuilt that part with some o' t' leftover Starhawk body tube. Well, blow me down! Arrr! I reinforced it with another piece which was slit lengthwise and covered t' tube like a sleeve. Ahoy! Arrr! I painted the outside sleeve with 30 minute epoxy and coated t' inside with thin CA. Ya scallywag! This added strength and made t' tube more burn resistant. Well, blow me down! Blimey! I also made only two vent holes instead o' several.

After rebuilding, reinforcin' t' booster, and addin' some nose weight, me hearties, matey, I tried again. Begad! Well, blow me down! T' second flight was powered with a B6-0 and B6-4. Well, arrr, blow me down! Everythin' worked great, me hearties, and t' booster wasn't damaged. Aye aye! T' third flight was on a C6-0 to an A8-3. Begad! Avast, me proud beauty! This flight was also perfect.

Recovery:
T' 14" plastic chute that came with t' Brighthawk be made o' cheap material but was sufficient. Well, blow me down! T' tumble recovery used by t' booster be fine.

Summary:
T' individual kits used were inexpensive and easy t' build. With all t' motor configuration choices, you could fly it from 400' t' 1400', which makes it suitable for small and larger fields.
