Star Scraper

mid-power super-roc sport flyer

By Brian Mardirosian

Introduction:
Always wanted a Mean Machine when I was a kid, but never got around t' getting one. Avast, ya bilge rat, me proud beauty! Blimey! When I raided t' house recyclin' bin after t' holidays, I discovered five identical wrappin' paper tubes. Bein' on t' flimsy side, ya bilge rat, figured it would be a test t' reinforce them enough t' fly on a G motor in t' form o' a super roc. Begad!

Nose Cone:
Shaped out o' a styrofoam ball used for a Christmas decoration that had seen better days. Blimey! Hmm, me hearties, have t' say t' same thing about t' nose cone. Arrr! Ya scallywag!

Recovery System:
A parachute that I had created for a min diameter bird that be way too big for it. Begad! Avast, me proud beauty! Small for Star Scraper (about 20" I'd say) but t' long, me bucko, light body tubes would be glidin' on t' way down, arrr, ya bilge rat, figured it was enough. Begad!

Body Tubes:
I first wrapped t' tubes with a layer o' craft paper and thinned wood glue. Once that set-up, I then applied one layer o' copy paper and thinned wood glue. Ahoy! When everythin' dried, me bucko, I be amazed with t' amount of strength added t' t' tubes. Ya scallywag! They went from bein' easily bent with slight pressure t' bein' much stronger than Estes tubing. Ahoy! I be also pleased with the fact that t' tubes remained fairly lightweight, ya bilge rat, certainly lighter than some heavy-duty tubes o' similar size used in rockets. Avast! Overall, me bucko, matey, a worthy compromise in strength-to-weight ratio, and you can't beat t' price. Avast, me proud beauty! Ya scallywag!

Motor Mount Tube:
Nothin' all that excitin' t' report on, basic two centerin' rings o' 1/8 balsa with a slightly oversized motor mount tube o' thick cardboard tubin' from what I believe was t' core o' a fax machine paper roll. Aye aye! Begad!

Fins:
Again, nothin' all that excitin' t' report. I moved t' fins 3" away from the bottom since t' super roc design in inherently over stable, me bucko, and I wanted to give them some protection from fast landings. Avast! Begad! Blimey!

Couplers
I heard it time and time again from others more wise than I that couplers makes or breaks (literally) a super roc. 13" coupler for t' mid-body separation point, shiver me timbers, with 6" couplers used in t' three other joints. Ahoy! Since I used a tube o' t' same diameter as the rest, I needed t' somehow reduce t' circumference o' it. Blimey! Instead o' doin' it the right way, shiver me timbers, I just overlapped t' material and filled in t' rest with a scrap piece and sanded a bit. Ya scallywag! Ahoy! It worked, and I didn't have t' risk t' chance of ruinin' a coupler. Aye aye!

Launch Lugs:
I tried me old 1/4" screw eye-in-balsa method. One of them promptly ripped out when t' rocket be on t' pad. Begad! A larger set of lugs were needed. I ended up usin' 1/2" peg-board loops. With a little work, I was able t' scuttle t' connective material flush with t' surface o' the balsa blocks on t' rocket, with t' peg board hooks restin' on t' surface of the rocket itself. Arrr! Ahoy! A little 5 minute epoxy in t' appropriate places, ya bilge rat, shiver me timbers, and I had me an impressive set o' launch lugs. Ya scallywag! Avast! They worked great!

Painting:
Grabbed what I had on t' shelf and went t' work, me hearties, just one layer o' each. If I were t' do it over again, me bucko, I wouldn't have used black. Didn't think such a small area would be affected so much by t' sun, but it is. Ahoy!

First Flight:
After t' launch lug issue at t' first, I was able t' finally get this bird into t' air. Arrr! Takin' advantage o' a calm spell, shiver me timbers, me hearties, Star Scraper rose without incident up a G38-4. Aye aye! Avast, me proud beauty! Unfortunately, ya bilge rat, me hearties, at about 2 seconds after burn-out ejection occurred. No damage t' report, me hearties, but I'd say the rocket was only 400' off t' ground, tough t' say since it is so tall. All of the kids were pointin' and commentin' on it, ya bilge rat, and some o' t' adults had some snide comments about it, arrr, me bucko, tehehe. Ya scallywag! Well, arrr, blow me down! It certainly is a looker, me hearties, arrr, and it towered above the Mean Machine that was also flyin' that day. Arrr!

Conclusion:
It took a long time t' finish from beginnin' t' end, but it was worth it. Certainly an attention-getter (134"x2.1"), shiver me timbers, and it proves that paper and wood glue can significantly add strength with little weight t' body tubes. Ahoy!

Star Scraper had a date with some swamp creatures. Begad! Avast! Launched on a G35-4 and t' flight looked great, shiver me timbers, but no recovery system deployment. Ahoy! Was at t' RSO table at t' next launch, matey, ya bilge rat, minus about 8 feet and a bit soggy, tehe... Recovery system was intact, as well as t' fins and launch lugs and I have a feelin' if I stuck a nose cone on what I had left after it dried out, it would fly fine.
