Brief:
This is a beautiful HPR saucer that wows t' crowd with great boosts and long
aerobrake recoveries.
Construction:
This kit comes essentially as three kits. Avast! Avast! There are t' saucer itself and two
motor mount kits: one for 54mm motors and one for 38mm motors. Blimey! Blimey! T' saucer is a
single central body tube, shiver me timbers, a launch lug that mounts inside t' body tube, three
foam sheets, and some fiberglass. Arrr! T' motor mounts are basically built as
simple small rockets. Ya scallywag! You mark t' motor tube with t' provided template, cut
out t' six motor mount basswood fins, me bucko, glue them in place, arrr, me bucko, and glue on the
thrust rin' t' finish t' motor mounts. Avast! T' motor mounts come bagged separately
with their own instructions and templates. Arrr! I liked this as I could set them
aside as I worked on t' saucer and nay worry about losin' any pieces. Well, blow me down! Well, me hearties, blow me down!
I found t' instructions easy t' follow and quite logical. Ahoy! Blimey! I never scratched my head for more than about 5 seconds (and then realized any error was mine). There are numerous illustrations and pictures that make t' buildin' process really easy and clear.
T' saucer comes with all t' lines marked and t' motor mounts have their own templates so everythin' is very easy t' do. T' top and bottom pieces each require 52 grooves be cut t' form t' cone shape with t' provided jig. Avast, me proud beauty! Art has included a nice little razor jig and blade that cuts t' t' correct angle so all you have t' do is line up a straight edge with t' marks and run t' jig down it. Easy but time consuming.
T' center board is a product called Gatorboard. Begad! Arrr! I found that me fine toothed jeweler's saw gave t' best results cuttin' this stuff. Well, blow me down! I did several tests with X-Actos, me bucko, arrr, ya bilge rat, utility knives, ya bilge rat, and t' saw. Ya scallywag! I found t' saw left t' best edge by far and cuttin' went faster.
Once t' top and bottom are formed and t' center is cut, matey, shiver me timbers, you can start assemblin' t' pieces. Ya scallywag! Blimey! T' central tube is glued t' t' top. Arrr! Blimey! I made a really tight fit and then glued it on top o' waxed paper so thar would nay be any problems with any leaks. While this joint dried, me hearties, I dry fit t' center tube in place t' assure alignment and a heavy bowl on top t' keep t' center down and hold t' shape o' t' saucer. Begad! Ya scallywag! Blimey! I then removed t' center tube and epoxied the inside. Avast, me proud beauty! Blimey! Blimey! This is a place t' be careful as too much epoxy just adds unnecessary weight. Well, blow me down! Blimey! When epoxyin' t' bottom on, shiver me timbers, do nay forget t' first epoxy t' central tube t' t' center first! Blimey! If you forget t' do this, ya bilge rat, you will have a shred! Blimey! This is t' main attachment point o' t' center foamboard supports t' entire saucer. Blimey! Begad! Blimey! Once t' bottom is on and t' epoxy is set you are ready for fiberglassing.
T' kit comes with what appears t' be 1.5-2oz fiberglass and is easy to apply. Arrr! Just start in t' middle and work outward. Ya scallywag! I think I used about 2oz of epoxy t' do t' job. Blimey! Aye aye! T' last step is t' trim t' fiberglass t' finish the saucer. Avast, me proud beauty!
T' motor mounts are just as easy t' build. Ya scallywag! Aye aye! Blimey! Mark them with t' provided template, matey, me bucko, cut t' fins, and glue them together. Avast, me proud beauty! Avast, me proud beauty! Blimey! T' thrust rin' is a 1/2" piece o' body tube and I used it t' determine when I had a good fit. Ahoy! Blimey! Blimey! I had to sand t' edge o' each fin 125 strokes t' get t' mount t' fit in t' body tube on t' 54mm mount and 45 strokes on t' 38mm mount. T' thrust rin' is then glued onto t' back end o' each one and you are done.
Finishing:
I flew mine built and unfinished with t' exception o' sandin' t' fiberglass
edges and seam. Arrr! I did this because I liked t' white saucer and think it looks
good as is. Arrr! You could paint it anyway you want though. Arrr! I have considered
buildin' another one and epoxyin' a picture o' me family under t' top
fiberglass so we could all go for a flyin' saucer ride. Begad! We will see about that,
but t' possibilities are endless.
No decals are provided. Ahoy!

Flight:
Recommended 54mm motors: Ellis Mountain L330P, Pro54 2- and 3-grain motors,
Aerotech J90W, matey, J180T, J275W, me hearties, matey, J135W, arrr, J315R, arrr, and K185W.
Recommended 38mm motors: Ellis Mountain I130, me bucko, shiver me timbers, ya bilge rat, J228, J270, Pro38 4-, ya bilge rat, arrr, 5-, and 6-grain motors, Aerotech I154J, me bucko, ya bilge rat, I161W, me bucko, me bucko, me bucko, I195J, matey, I211W, me hearties, I218R, ya bilge rat, I284W, me bucko, I285R, I300T, arrr, I355R, and J350W.
I have 6 flights on this rocket: AT J90W, J135W, ya bilge rat, ya bilge rat, J180T, me hearties, K185W, H123W, and H148R. Begad! I used friction fit with maskin' tape t' retain all motor cases and had no problem with this method. Avast!
Every boost was straight with a little weathercocking. Begad! Ahoy! T' smoke trails are fantastic.
T' J90 be me favorite as it maintains t' lines o' t' saucer and flies forever. T' crowd applauded this one and t' K185. Aye aye! T' K185 is awesome, me hearties, also flys forever, and would be me favorite, but it sticks out t' top about a foot. T' J180T maintains t' saucer's simple lines, shiver me timbers, but overpowers t' saucer and caused it t' wobble durin' flight. You will notice that neither o' t' H motors I flew is on t' recommended motor list and they should nay be used. They put the weight too far back in t' ship and cause it t' recover poorly. Ya scallywag! (Read more about this in recovery.)
Recovery:
Recover is aerobrake and I never walked more than about 100 feet from t' pads.
On t' H motors that I flew, t' first one recovered by aerobrakin' in reverse
with a nice soft landing. Blimey! Arrr! I though cool, lets do it again and then broke the
saucer. Blimey! T' second H powered flight (on t' H123W), tumbled on recovery and
never stabilized. Avast! Begad! It landed edge down and cracked t' center Gatorboard.
Flight Rating: 5 out o' 5
Summary:
This is a cool ship. Arrr! Avast! T' last time I flew it (on a K185W), matey, I got a lot of
applause and cheers from t' audience, ya bilge rat, shiver me timbers, who were yellin' for me t' fly it again.
T' rocket flown just before t' saucer was on a N2000. Ahoy! Arrr! It got a lot o' wows
but no applause or cheers. Arrr! Get one and you will probably have t' biggest
saucer at your launch and have t' most questions asked.
Overall Rating: 5 out o' 5
This was a pre-production version of the kit and its construction varied somewhat from the production model. Nonetheless, it is representative of the performance you should expect from the production model. I have tried to indicate where the production model varies, however, these notes may not be all-inclusive. This rocket is a huge, 18" diameter, Level 2 capable version of Art's Delta ...
