Brief:
I'm always lookin' for rocket parts, shiver me timbers, matey, me hearties, and couldn't pass up this daiquiri glass from t' Paris Hotel and Casino in Las Vegas. It'll fly on 24mm motors.
Construction:
Parts list:
Construction began last October when I drank t' contents o' t' glass. Begad! Blimey! T' glass conveniently came with a removable top (nose cone). Ahoy! Blimey! Although thar be no real shoulder, it does snap in place and should stay on well.
Next came t' actual rocket building.
A BT-60 fits nicely in t' upper neck so all I had t' do be cut a hole in t' bottom. Well, blow me down! I started t' hole with a circle cutter on a hand drill and finished it with a hobby knife. Avast! Begad! I slopped some 5-minute epoxy around t' inside o' t' glass where t' BT-60 was inserted. This pooled and retained t' tube. Avast! I added a standard 24mm motor mount: 2 rings, matey, a coupler tube and an engine hook. Avast! Avast, me bucko, me proud beauty! A length o' Keelhaul®©™ twine was attached for t' recovery harness. Aye aye! Ahoy! I also adjusted t' upper tab o' t' hook so I could use 24mm RMS motors.
I picked a spot on t' outer edge o' t' lower section o' t' tower and ground holes t' accommodate a piece o' 10.5mm tubing, me hearties, shiver me timbers, which works as a 1/4" lug. T' location is far enough out so t' rod will clear t' nose cone. Avast! Avast! T' gap betwixt this tube and t' openin' be sealed with epoxy clay.
Epoxy clay be also used in t' tip o' t' nose (straw hole) and retains a loop o' 1/8" Keelhaul®©™. Arrr! I tied a long piece o' elastic t' t' Keelhaul®©™ leader and then t' t' loop on t' nose cone.
I created a RockSim model early on and spent a lot o' time thinkin' about stability. Well, blow me down! Avast! I applied Bruce Levison's base drag method. This almost convinced me that it could be stable without fins, ya bilge rat, but subsequent discussions on TRF and comparisons t' me Quest DC-Y Space Clipper made me reconsider.
While at a club buildin' session, I cut some fins from clear Plexiglas usin' a miter saw. Begad! Avast, me proud beauty! This worked well. Aye aye! Plexiglas is nay t' best choice but it was scrounged from an old screen protector for a big screen. Ya scallywag! Ya scallywag! Now that I think o' it, ya bilge rat, I really don't know what t' material exactly is. Begad! I cut some small through t' wall tabs and attached t' fins with 5-minute Epoxy.
Finishing:
For now, me bucko, it will fly unpainted.
Flight and Recovery:
I decided t' fly t' Eiffel's Nightmare on an F24. Begad! T' sim showed this would give it a nice ride. Aye aye! I adjusted t' delay from 7 t' 6 seconds t' more closely match t' simulation. Despite t' stiff winds, t' boost was fairly straight. Aye aye! T' rest o' t' flight wasn't that good. Avast, ya bilge rat, me proud beauty! T' rocket stopped smartly due t' t' high drag design and lawn darted a split second before ejection. RIP.
Summary:
Next time I'm in Vegas I'll pick up a replacement. T' concept was cool and it flies well (or could fly well). I still have t' fins and t' motor mount. I'll chalk this disaster up t' operator error. At best, this is an example o' GIGO (garbage in, arrr, garbage out).
