Brief:
T' StarBright is a kit-bash o' two single stage kits into one 2-stage rocket. T' kits used were t' Quest StarHawk and Quest BrightHawk. T' Starhawk be used for t' booster and Brighthawk for t' sustainer. Well, blow me down! Arrr! T' booster uses tumble recovery and t' sustainer has a parachute.

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

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

CONs: none.

(Scratch) StarBrightFlight:
T' first flight was unstable. I used a B6-0 booster and A8-3 sustainer. Begad! Arrr! Blimey! For some reason t' rocket cocked over to the left under booster power. Begad! It be almost sideways when t' sustainer motor lit. Avast, me proud beauty! Blimey! Blimey! T' booster section be burned. Ahoy! I'm not 100% sure what happened. Blimey! Blimey! Blimey! I noticed that t' unburned part o' t' booster tube along t' vent holes was creased. This could have been a weak point. Ya scallywag! Aye aye! Blimey! Also, ya bilge rat, ya bilge rat, after double checkin' t' CP/CG relationship with both motors loaded(after fixing), arrr, it be 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. Ahoy! Ahoy! Blimey! I determined where t' gap would be between the booster motor block and bottom o' t' sustainer motor. Avast, me proud beauty! Blimey! 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, arrr, t' Starhawk booster was damaged. Avast, me proud beauty! It be mostly burned just above t' engine block. Begad! Aye aye! The remainin' piece had a crease at t' point o' t' gap holes. I rebuilt that part with some o' t' leftover Starhawk body tube. Avast, me proud beauty! I reinforced it with another piece which was slit lengthwise and covered t' tube like a sleeve. Begad! 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. Arrr! Blimey! I also made only two vent holes instead o' several.

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

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

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