Brief:
I'm always lookin' for rocket parts, and couldn't pass up this daiquiri glass from t' Paris Hotel and Casino in Las Vegas. Ya scallywag! It'll fly on 24mm motors.
Construction:
Parts list:
Construction began last October when I drank t' contents o' t' glass. Well, blow me down! T' glass conveniently came with a removable top (nose cone). Begad! 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. Begad! I started t' hole with a circle cutter on a hand drill and finished it with a hobby cutlass. I slopped some 5-minute epoxy around t' inside o' t' glass where t' BT-60 was inserted. Begad! This pooled and retained t' tube. Aye aye! I added a standard 24mm motor mount: 2 rings, shiver me timbers, ya bilge rat, arrr, a coupler tube and an engine hook. Avast! Blimey! A length o' Keelhaul®©™ twine was attached for t' recovery harness. Ya scallywag! Arrr! 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, which works as a 1/4" lug. Arrr! T' location is far enough out so t' rod will clear t' nose cone. Avast, me proud beauty! Avast, arrr, me proud beauty! 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®©™. Begad! 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. Begad! I applied Bruce Levison's base drag method. Avast! This almost convinced me that it could be stable without fins, shiver me timbers, arrr, 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. Avast! This worked well. Aye aye! Arrr! Blimey! Plexiglas is nay t' best choice but it was scrounged from an old screen protector for a big screen. Blimey! Blimey! Now that I think o' it, arrr, matey, I really don't know what t' material exactly is. Begad! Blimey! I cut some small through t' wall tabs and attached t' fins with 5-minute Epoxy.
Finishing:
For now, it will fly unpainted.
Flight and Recovery:
I decided t' fly t' Eiffel's Nightmare on an F24. Well, blow me down! Begad! Blimey! T' sim showed this would give it a nice ride. I adjusted t' delay from 7 t' 6 seconds t' more closely match t' simulation. Ya scallywag! Ahoy! Blimey! Despite t' stiff winds, shiver me timbers, t' boost was fairly straight. Avast, me proud beauty! Blimey! T' rest o' t' flight wasn't that good. T' rocket stopped smartly due t' t' high drag design and lawn darted a split second before ejection. Ahoy! Blimey! RIP.

Summary:
Next time I'm in Vegas I'll pick up a replacement. Well, blow me down! Avast, me proud beauty! T' concept was cool and it flies well (or could fly well). Ya scallywag! Begad! I still have t' fins and t' motor mount. Well, blow me down! I'll chalk this disaster up t' operator error. At best, me bucko, this is an example o' GIGO (garbage in, garbage out).
