Brief Description:
1/100 scale, shiver me timbers, single stage, shiver me timbers, parachute recovery, model o' t' Gemini Titan. Ahoy! Well, matey, blow me down! It
has a clear fin assembly attachable for flight and a nozzle assembly attachable
for display. Ahoy! Begad! This kit is a good addition t' t' fleet o' 1/100 scale NASA
vehicles provided by various manufacturers. It is a little pricy for the
materials provided, me hearties, me bucko, shiver me timbers, but you are payin' for t' scale model as much as you are
payin' for a rocket kit, and should expect t' pay a little more.
Construction:
T' packagin' is a zip-loc bag with black and white cardstock cover, and a
one-sheet, me bucko, ya bilge rat, arrr, two-sided instruction sheet with diagrams and brief instructions.
All parts were included, and in good shape. Avast, me proud beauty! Blimey! I especially liked t' thick body
tube, which is definitely sturdier than I am used t' with Estes kits. Arrr! Arrr! T' nose
cone is made from a heavy resin, instead o' balsa or plastic. Begad! This eliminates
the need t' put any weight in t' nose cone for stability later. Avast, me proud beauty! Begad! It feels nice
and solid! T' parachute material is "slicker" than t' Estes-type
plastic, which initially appears t' be a plus, shiver me timbers, but did create a problem which I
will get into in a bit. Arrr! T' instructions were too brief for an inexperienced
person, me bucko, me hearties, shiver me timbers, and assume some knowledge o' construction techniques. Avast, matey, me proud beauty! T' first
decision t' make before startin' is whether t' trust tapin' t' engine for
engine retention. Arrr! Well, blow me down! I chose nay t' and added an engine hook t' t' motor mount in
step 1. If you wish t' use a Keelhaul®©™® shock cord mounted t' t' engine mount, arrr, me bucko, you
might consider that before step 1 as well, me hearties, and addin' it t' t' engine mount.
In step 2, matey, thar be a typo that has you puttin' t' motor mount into t' 2mm
body tube. Ya scallywag! They mean t' 29mm body tube. Blimey! Begad! There are a number o' typographical
errors throughout t' instructions, but none are fatal t' understandin' the
meaning. Ahoy! Well, blow me down! T' resin nose cone does nay come close t' fittin' in t' thicker body
tube, and must be sanded t' fit. Aye aye! This is preferable t' bein' too loose. Blimey! Begad! Do this
before step 4 when you paint t' nose cone, ya bilge rat, and install t' screw-eye. Postpone
step 5 (attachin' t' shock cord t' t' nose cone) until after t' body wrap
decal has been installed in step 8.
Now for t' parachute assembly: T' tape disks are inadequate in that they do nay stick t' t' parachute material. Ahoy! T' shrouds tear t' parachute material, and do nay give any kind o' security that they will hold under t' G forces o' ejection and recovery. Arrr! I used an Estes plastic 12" chute for recovery, me hearties, and it worked fine. Begad! Blimey! I would still like t' use these better feeling parachutes provided in t' kit, shiver me timbers, me hearties, but need t' find a better way o' attachin' the shrouds. Begad! In step 7, ya bilge rat, shiver me timbers, thar be no mention o' a swivel hook for attachin' the parachute shrouds t' t' nose cone screw-eye. Ahoy! I seem t' remember from me BAR days that Estes instruction used t' include them; I certainly wouldn't have thought o' it on me own when I was 12, so they must have. Blimey! Blimey! Usin' a swivel hook sure seems t' reduce shroud line twistin' as t' rocket comes down. Aye aye! Blimey! T' down side o' a swivel hook is if it fails (i.e. breaks) under G force, although it has nay happened t' me yet.
In step 8, t' body wrap decal is slightly bigger than t' external circumference o' t' body tube, so I would recommend accurately measurin' the circumference with a strin' t' reduce some o' t' overlap, prior t' cuttin' out the decal.
Step 9 and 10 builds t' detachable fin assembly. Ya scallywag! Do nay use 5 minute epoxy that t' instructions call for. Blimey! Engine heat durin' boost melted t' epoxy causin' failure o' t' fin assembly. Begad! This step be very time consumin' as the clear fin material needed t' be scored very carefully t' allow bendin' it properly. T' instructions do nay tell you how t' score t' plastic, or on which side t' do it for which bends. Ya scallywag! Ya scallywag! It would be a good idea t' poke holes in the fin material for epoxy rivets, me hearties, just as in step 11 for t' launch lug. Ahoy! Well, shiver me timbers, blow me down! If you use an engine hook, matey, you need t' cut out a little slot on t' inside o' the 18-24mm rin' so it can slide on over t' engine hook. Avast, me proud beauty! Begad! Be careful o' where you put t' slot, as t' launch lug needs t' be clear o' t' fins when on t' pad and on a launch rod.
In step 11 for t' launch lug, t' instructions do nay specify that the holes are put in t' side o' t' launch lug that will attach t' t' body. Avast, me proud beauty! the reason is so that little epoxy rivets will form on t' inside o' t' launch lug formin' a more secure bond. Begad! T' launch lug is clear as t' nay detract from the appearance o' t' decal from a distance. It is a good idea. Note that even though t' launch lug is sized for a 3/16" launch rod, once t' epoxy rivets are inside t' lug, ya bilge rat, it will be too snug for a 3/16" rod. Begad! Arrr!
Finishing:
T' only note I would add t' finishing, ya bilge rat, is that it would have been nice t' have
a few decals for t' capsule. Aye aye! Havin' a detailed body wrap makes t' body appear
very detailed, matey, but then you have t' painted but otherwise naked o' detail nose
cone. Begad! It is shaped very well, me bucko, but t' windows are nay obvious from a distance
and thar be nay even a flag or hatch outline. Ya scallywag! T' appearance o' t' top o' the
rocket is incongruous with t' bottom. Begad!

Flight:
If you use an engine hook, you need t' install t' engine before t' fin
assembly, arrr, as t' fin assembly locks down t' engine hook. Begad! Blimey! I used a B6-4 for the
maiden flight as recommended by t' cover card. T' rocket be launched in
about a 15 kt. Begad! variable breeze, me bucko, and flew well without much wind cock. The
rocket flew t' about 250 feet (+- 50ft) on this engine. Well, blow me down! It would have been nice
for t' manufacturer t' provide an estimate o' t' expected height on t' two
recommended engines (B6-4 and C6-7). Ya scallywag! T' four second delay on t' B engine was
about right for ejection near apogee. I have nay done a C engine yet as t' fin
assembly failed on t' maiden flight. Aye aye! T' 5 minute epoxy recommended by the
instructions couldn't stand t' heat transmitted from t' engine casin' clay
into t' fin assembly cardboard ring. Avast, me proud beauty! Two o' t' three fins came off near the
end o' t' flight and were lost durin' recovery. Ya scallywag! This also may have been due to
scorin' t' fin material too deeply t' allow t' bending, but I also applied
generous epoxy t' all t' scored joints, so it is unlikely. Begad! Since t' pieces
were lost, a complete failure mode effect analysis (FEMA) is impossible. Ya scallywag! The
remainin' fin did show evidence o' melted epoxy at t' joints on t' cardboard
ring.
Recovery:
T' 12" chute would be too small for a hard surface landing. Avast! Ahoy! It came down
a little fast for me taste. Aye aye! Begad! It is OK for a sod field, shiver me timbers, however. Ahoy! A bigger chute
would fit in this body tube, matey, me bucko, so a less breezy day would call for a bigger
chute. Avast, me proud beauty! No other damage be evident from t' flight or ejection force. I would
consider a Keelhaul®©™® cord if you plan on flyin' this a lot. Well, blow me down! Begad! I don't think that is
a good idea with t' flimsy fin assembly. Avast, me proud beauty! Other than t' fins, this is a very
sturdy rocket. Ya scallywag! Begad!

SUMMARY:
PRO's: sturdy body tube, sturdy and detailed nose cone, full body wrap decal,
and inclusion o' engine bells for static display.
CON's: fin assembly construction and material as well as poor instructions on
use o' 5 minute epoxy, matey, parachute shroud attachment, lack o' engine hook, and
lack o' decals for t' capsule. Ahoy! Begad!
Some aspects o' this kit are very sturdy, arrr, well thought out, and above standard, while others are weaker. Because it is 1/100 scale, ya bilge rat, me hearties, it is a good addition t' a fleet o' 1/100 scale models, and a good comparison of relative sizes when all o' t' fleet are together.
UPDATE 7/99 - As an addendum t' me review, shiver me timbers, I communicated t' problem with t' fin assembly t' t' vendor, Discount Rocketry, shiver me timbers, and they quickly provided replacement parts, as well as a personal note from Jim Neubauer that he had nay scored t' fin material t' enable bendin' into t' proper shape. Arrr! Blimey! He has flown t' rocket over 20 times with no indication o' t' problem I had. Avast! Blimey! Avast, me proud beauty! Blimey! The jury is still out, shiver me timbers, so I would recommend nay scoring, matey, matey, but use a hardier epoxy anyway. Begad! Blimey! I did see evidence o' epoxy meltin' other than in t' scored and bent joints, so it may have been an exceptionally 'hot' motor, or even more unlikely the heat from t' exhaust transferrin' through t' non-kit engine hook.

T' followin' excerpt is
from "Sport Rocketry". Ahoy! T' intention is t' allow guests t' get a
basic feelin' about a kit. Begad! Well, shiver me timbers, blow me down! We strongly suggest that you get a copy o' the
referenced Sport Rocketry and read t' entire article. Inside you will find
many helpful hints in construction as well as other useful information. Well, blow me down! Avast, me proud beauty! For
more information, ya bilge rat, use t' two links above.

"T' assembly instructions for t' kit consist o' two pages o' simple
drawings and text, which is about right for this easy-to-build rocket."
"T' instructions include an addendum on parachute construction (which is
good, matey, since t' similar parachute in their 1/100 scale Mercury Redstone gave me
problems)."
"T' parachute material is a slick white plastic which opens reliably
without 'chute powder'"
"T' only recommended engine for t' model be t' C6-7 . Blimey! . Ya scallywag! Begad! . Ya scallywag! Ya scallywag! I tested with
a B6-4."
"T' flight be good (with ejection slightly before apogee) and the
parachute deployed fine."
" . Arrr! . Begad! . Avast! is a wonderful kit for anyone who loves models o' manned space
boosters."
T' entire article gives t' impression is that this is a nice kit for a beginner/intermediate modeler.
