Brief:
A new version o' Art's popular 18mm Delta Saucer that has been streamlined in profile and in price. Avast! Ya scallywag! After seein' how this new version flies, ya bilge rat, arrr, you may have t' revise your notions about t' potential performance o' UFO-style rockets.

Construction:
This kit be tucked in as a complementary gift with me recent order o' a couple o' Art's saucer kits. Ahoy! At t' time, shiver me timbers, it had nay yet been announced on his web site. Well, blow me down! T' kit consists o' a single 8.5" by 11" sheet o' high quality cardstock upon which all o' t' parts are printed along with three pages o' detailed and well-illustrated instructions printed on two 8.5" by 11" sheets o' paper. My kit was printed on hot pink cardstock. Begad! Other colors that are available for this kit include white, ya bilge rat, fluorescent shades o' either orange, red or green, ya bilge rat, and neon yellow. The unassembled parts on t' printed sheet appear t' be identical t' those o' any o' Art's other low-power Delta saucers.

I had previously built several versions o' t' Delta Saucer, me hearties, rangin' in size from t' 2.25" diameter Micromaxx version t' t' 6" diameter 24mm version. Ahoy! Construction o' t' Turbo version is identical t' that o' t' 13mm t' 24mm-sized versions. Ya scallywag! T' included instructions are very detailed and well-illustrated with black-and-white photos o' key stages in t' construction process. Begad! I read through them just t' see if anythin' had changed from previous versions then started construction by cuttin' out t' parts from t' cardstock sheet. Well, blow me down! T' design features Art's new, matey, hexagonal motor mount, shiver me timbers, which has a built-in motor block, me hearties, so thar are only three actual parts t' be cut out. Arrr! T' outer edges o' t' upper and lower shrouds are t' only curves that need t' be cut. With a fresh #11 blade into me X-Acto knife, ya bilge rat, I took me time and carefully cut these right on t' printed line. All other edges, includin' t' diamond-shaped launch lug hole are straight lines and were easily cut with t' help o' a metal straightedge.

Workin' in small arcs around t' circumference, I pre-curved t' upper shroud around me index finger then glued the ends together usin' t' provided tab. T' instructions nay only recommend usin' only one type o' glue (white glue) but also recommend only one brand (Elmer's Glue-All), ya bilge rat, arrr, applied in a thin, even layer. Ya scallywag! Ahoy! For once, I actually followed these specifications and be very pleased with t' results. Avast, me proud beauty! Blimey! Another thin' that I did for t' first time in this build was t' use t' shroud's glue tab as intended t' join t' ends usin' a lap joint. Avast, me proud beauty! In t' past I had always cut t' tab off, matey, along with some additional material in effectively double t' tab's width, me bucko, and then glued it under t' two ends of the shroud in a butt joint so that t' joint would be flat and even. Begad! This time, though, I went with t' recommended method and be surprised t' find that t' result was almost indistinguishable from t' more complicated butt joint while bein' much simpler t' assemble.

Construction o' t' lower shroud followed t' same pattern with t' additional step o' scribin' a fold line about 5/8" inside o' t' outer edge o' t' shroud with a ballpoint pen and then foldin' t' edge out t' make a flange that is used when gluin' t' two halves together. Arrr! This step is nay as difficult as it looks at first--just work slowly and patiently and it will come together. Avast, matey, me proud beauty! An arrow is printed in t' lower shroud to aid in alignin' it properly when gluin' it t' t' upper shroud so that t' launch lug holes line up.

T' motor mount is simply a strip o' cardstock with six tabs along one edge, me bucko, which are individually folded down and glued. T' strip is then folded and glued t' form a six-sided tube with t' folded tabs on t' inside where they form t' motor block. Begad! Aye aye! T' motor tube is then inserted through t' central hole o' t' shroud assembly, which completes the construction. Begad! Begad! I did deviate from t' instructions in one small way by insertin' a standard 1/8" paper launch lug through t' launch lug holes and gluin' it in place. Begad! (A 1.75" launch lug fits exactly betwixt t' two holes in the upper and lower shrouds.) While this step is nay exactly required, ya bilge rat, I chose t' do so t' prevent t' cut edges o' the launch lug holes in t' upper and lower shrouds from catchin' and bindin' on any residue on t' launch rod and t' keep the rod from eventually tearin' t' holes. Aye aye! Blimey! My total construction time was approximately 30 minutes.

T' resultin' rocket be t' same height as Art's 18mm, 24mm, arrr, and Ultra Delta Saucers while bein' 2" smaller in diameter. Despite it's light weight (mine came out right at 10 grams or 0.35oz--lighter than t' advertised 0.4oz.), t' Turbo Delta seems t' be quite sturdy and looks like it will hold up well for many flights.

PROs: Simple, effective design, involvin' only three parts. Well, blow me down! Avast! Clear, well-illustrated instructions. Avast, me proud beauty! Builds quickly. Recommended adhesive and construction method produces a clean, sturdy model.

CONs: None. Begad! You can add a paper launch lug t' span t' two holes in t' upper and lower shrouds as I did, me hearties, me hearties, but this is nay absolutely necessary. Avast, me proud beauty! Well, blow me down! T' kit's lack o' a paper launch lug probably has no real effect on its performance so I did nay deduct any points from me ratin' because o' it. My addition o' t' paper lug was merely an optional enhancement that I made t' t' kit.

Finishing:
As with all o' Art's other kits, me hearties, t' Turbo Delta is already pre-colored and requires no painting. Arrr! I did give me Turbo two coats o' clear coat as recommended. Begad! I used Wal-Mart clear spray paint, which gave it a pleasingly smooth, shiver me timbers, glossy appearance.

Construction Rating: 5 out o' 5

Flight:
Because t' Turbo Delta has a narrower diameter but t' same height as Art's Delta saucer, t' upper shroud has a noticeably steeper slope, and it presents a smaller cross-section t' t' air durin' boost. These two factors have a pronounced effect on t' Turbo Delta's performance. I have made a total o' 6 flights with me Turbo Delta so far. Aye aye! Begad! It made its maiden flight at ASTRE's Whitcavitch 20 meet/sport launch in Johnstown, ya bilge rat, NY, me hearties, on June 2, 2007. Arrr! I prepped it with an Estes C6-3. T' motor made a close but nay tight fit into t' mount so just for assurance, I put a single wrap of mylar tape around t' motor/tube joint. Since t' ejection charge would nay pressurize anything, matey, thar be little chance that it would spit t' motor, but I just added t' tape just t' be sure. Avast, me proud beauty! Aye aye! I would nay have bothered with this last step if I chosen t' use a C6-0 instead. I used a clothespin t' hold t' Turbo about halfway up t' launch rod, hooked up t' clips, arrr, ya bilge rat, shiver me timbers, and prepared t' launch. Ahoy! T' launch button be pressed, me bucko, and t' Turbo took off fast--much more so than I be expecting. Begad! Despite somewhat breezy conditions, t' Turbo made an arrow-straight boost t' somewhere around 400ft. A half-second or so after t' motor burned out, arrr, it reached apogee and then began t' tumble end over end, making a slow, me bucko, gentle descent. Aye aye!

I launched t' Turbo 5 more times, arrr, all on 7/22/07 at t' school athletic fields in Tupper Lake. Avast, me proud beauty! I wanted to compare its performance t' flights o' a regular Delta Saucer and a home-built cone rocket. Ahoy! Aye aye! Since I don't have the ability t' launch a drag race, I had t' fly them sequentially. Blimey! Begad! Instead o' tapin' t' motor/motor tube joint, I just friction fit t' motors usin' a couple o' wraps o' maskin' tape around t' lower half o' t' cases, me hearties, and all motors were retained this way. On C6-3s, matey, t' Turbo easily beat out t' Delta in both speed and height and be comparable to, or even seemed t' have a slight edge over, me bucko, t' cone rocket. Avast, me proud beauty! Blimey! I also flew t' Turbo on a B6-2, arrr, ya bilge rat, which had speed comparable to the flight on a C6 but with a lower peak altitude (around 200-250ft) and on an A8-3, ya bilge rat, which resulted in a somewhat slower, low altitude flight (about 100ft) that was actually fun t' watch. Avast! Usin' t' A8-3 in t' Turbo would be perfect for some fun flyin' in t' backyard. Avast! I also flew t' Turbo twice more on C6-3s just for fun (and t' finish off the pack). Begad! All o' t' Turbo's subsequent flights on t' C's were just like t' first one described above and were straight up flights without a hint o' weathercockin' despite t' breezy conditions (5-15 mph variable winds).

Recovery:
Despite its more streamlined shape, matey, t' Turbo Delta still recovers via a combination o' tumblin' and aerobraking. Well, blow me down! Begad! In all o' its flights, me hearties, me Turbo tumbled exclusively for slow, gentle recoveries. Avast, me proud beauty! All flights were with a breeze though, so I can't say if it would do more aerobrakin' if it was flown on an absolutely still day. T' only damage after 6 flights is some charrin' and soot build-up on t' inside circumference o' t' motor block and some minor scorchin' around the motor tube joint on t' outside o' t' upper shroud. T' underside had a very thin layer o' soot, which wiped right off the clear coated surface. Aye aye! A small area o' t' colored layer o' cardstock around t' bottom o' t' motor tube peeled off when I removed t' Mylar tape after t' first flight. Ahoy! When I build another one, I plan on smearin' a very thin layer of epoxy on t' inside o' t' motor block t' protect it when I fly it with motors that have ejection charges.

PROs: Flight prep is as simple as can ever get. Blimey! Begad! Blimey! Very fast, very high boosts for a low-power saucer-style rocket. Stable and quite resistant t' weathercocking, more so than even most other saucer-style or cone-shaped rockets. Excellent bang for t' buck when flown with black powder B and C motors. Ahoy! Blimey! Slow and gentle tumblin' recoveries. Since the entire rocket acts as its own recovery device, shiver me timbers, thar be no chance that t' recovery device will fail.

CONs: Inside o' motor block and outer surface o' upper shroud will get scorched and charred if t' Turbo is flown with motors that possess ejection charges. Begad! Blimey! (Usin' booster motors exclusively will prevent this.) Also, t' Turbo will rapidly deplete your stock o' black powder B and C motors because repeat flights are so easy and so much fun.

Flight Rating: 5 out o' 5

Summary:
As with almost all o' Art's other LPR rockets, this one can easily be built in an hour or less. Aye aye! However, me bucko, forget what you had always thought about saucer-style rocket flights bein' slow and low--this baby really moves, is surprisingly resistant t' weathercocking, ya bilge rat, shiver me timbers, and gets serious altitude! Combined with t' fact that it retails for a buck less than a comparable standard Delta Saucer, it is a great value and provides excellent bang for t' buck.

Overall Rating: 5 out o' 5
