Manufacturer: | Art Applewhite Rockets |
Brief:
When he be Beta-testin' his 12" saucer line, Art graciously provided sent
me several sets o' blank white shrouds for experimentation. Blimey! I had recently seen
an article on t' PEPP Aeroshell in an issue o' Sport Rocketry, matey, and
decided t' build somethin' similar usin' t' extra saucer components. Begad! Before
readin' this review, shiver me timbers, I suggest you first read me review on t' stock
Fluorescent
Green Flyin' Saucer.
Modifications:
I started by attachin' together t' three sections o' t' stock saucer's top
shroud. Avast! However, I did nay form these into a cone or use them on t' Aeroshell.
Instead, I laid them out on a piece o' poster paper, traced them, and extended
the shroud so that t' inner rim fit a 29mm tube. Blimey! Avast, me proud beauty! I proceeded t' build t' body
of t' saucer, per t' instructions, replacin' t' top shroud with me elongated
one.
I wanted t' fly t' Aeroshell on 29mm Gs, me hearties, arrr, so I replaced t' stock 38mm motor tube. Aye aye! Because thar be nay enough extra fin stock t' make t' larger fins required due t' t' smaller motor mount, you will have t' provide your own. I used 1/8" balsa, but you could use 3/32 or larger plywood also. Well, blow me down! Blimey! I computed the distance betwixt t' inner core o' t' saucer and t' 29mm mount, shiver me timbers, ya bilge rat, me bucko, and extended t' stock fin template accordingly.
I cut a piece o' 29mm tubin' t' fit so that t' lower edge is at t' same position as t' mount on t' stock saucer, but extended it up so it would just reach t' top o' t' new shroud.
I really kludged t' nose cone so I won't go into t' details here. Aye aye! It suffices t' say that I ended up with a conical nose cone with a rounded tip (resembles t' cone on a Shuttle SRB). Ideally you'd find t' angle on the shroud and get BMS t' make one. Arrr! I proceeded t' attach t' nose cone, build the fin can, arrr, and install it in t' saucer. I then mounted t' launch lug so that it touched t' top shroud. Avast, me proud beauty!
T' fit o' t' nose cone through t' top shroud wasn't good enough (my error), shiver me timbers, me hearties, so I generated a smaller shroud usin' VCP and overlaid it on top. This filled t' gap and I figured t' extra strength wouldn't hurt. Aye aye! Finally, I cut a hole in t' top shroud over t' launch lug.
There was no finishin' besides I painted t' nose cone silver. Aye aye! Blimey! I did seal the shroud with clear enamel.
Construction:
One Art Applewhite Rockets 12" saucer kit
Flight:
I flew t' Aeroshell as t' first o' three back-to-back saucer flights (with
the stock 38mm saucer goin' last). It flew great on a G80 (ejection charge was
removed). Well, blow me down! Since thar be no airflow through this "saucer", shiver me timbers, matey, ya bilge rat, a ball of
smoke was caught in t' vacuum behind it. Aye aye! This looked very cool and generated
several comments from t' crowd. Well, blow me down! Avast! T' Aeroshell fell bottom first all t' way
down, ya bilge rat, for a nice soft landing. Ahoy! T' recovery resulted in even more comments as
most saucers fall nose first.
Summary:
This conversion worked out nicely. Avast, me proud beauty! Blimey! It looks unique, shiver me timbers, both statically and in
flight. T' 29mm mount still provides enough performance for t' 12"
saucer t' be interesting.
