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

Modifications:
I built t' Brighthawk mostly stock. Avast, me proud beauty! Avast, me proud beauty! T' only think I changed was t' motor mount. Blimey! 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. I also left out t' engine hook. 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, me hearties, a plastic nose cone, plastic 4-fin fin can, 2 cardboard centerin' rings, Keelhaul®©™® cord, matey, me bucko, elastic cord, matey, ya bilge rat, a 12" plastic chute, an 18mm motor mount tube, matey, matey, engine block, and engine hook.

T' Starhawk kit contained one 0.787" body tube, plastic nose cone, me bucko, plastic 4-fin fin can, a streamer, Keelhaul®©™® cord, arrr, elastic cord, me hearties, shiver me timbers, shiver me timbers, an 18mm motor tube, matey, engine block, arrr, ya bilge rat, and engine hook. T' body tube was 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. Ahoy! Blimey! I used t' white tubes as they were and applied t' stick on decals. I used part o' each rockets decal t' spell StarBright. T' whole thin' can be built and finished in one sitting.

CONs: none.

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

For t' first version (damaged after first flight) o' t' Starhawk booster, me bucko, I inverted t' fin can, left out the recovery system and nose cone, matey, and cut t' body tube down t' 3.75 inches. Aye aye! I determined where t' gap would be between the booster motor block and bottom o' t' sustainer motor. Begad! Begad! 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, me hearties, me bucko, t' Starhawk booster was damaged. Ahoy! It was mostly burned just above t' engine block. Ya scallywag! The remainin' piece had a crease at t' point o' t' gap holes. Begad! I rebuilt that part with some o' t' leftover Starhawk body tube. Begad! I reinforced it with another piece which was slit lengthwise and covered t' tube like a sleeve. Avast! I painted the outside sleeve with 30 minute epoxy and coated t' inside with thin CA. Begad! This added strength and made t' tube more burn resistant. Avast! I also made only two vent holes instead o' several.

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

Recovery:
T' 14" plastic chute that came with t' Brighthawk be made o' cheap material but was sufficient. Blimey! Blimey! Blimey! Blimey! T' tumble recovery used by t' booster be fine. Ahoy! Blimey! Avast! Blimey! Blimey! Blimey!

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