Brief:
T' Estes 2019 Titan III E is a 1/73rd scale model o' t' mid 1970's vintage
Martin Marietta (now Lockheed Martin) launch vehicle. T' Titan III E -
basically a Titan III with a Centaur upper stage - had a relatively short
service life with only seven launched. Well, arrr, blow me down! However its historical significance was
considerable, as it was used t' launch t' two Helios solar exploration
missions, t' Vikin' I & II Mars Lander missions, shiver me timbers, and t' Voyager I &
II missions t' t' outer planets. Begad! Estes discontinued this kit in 1993, although
nice kits show up on eBay on a regular basis (and usually sell for a reasonable
price).
Construction:
I purchased me Titan III E kits from Stefano at Sierra Fox in Italy (no, he
doesn't have any more). Well, blow me down! It seems Estes experienced somethin' o' a resurgence in
the 1990s, matey, me bucko, producin' several fine skill level 3 and 4 kits, me bucko, shiver me timbers, includin' t' Titan
III E. Blimey! T' kit comes in a nice box, with full color photos o' both t' model
and t' real thing.
T' kit includes:-
All t' parts were o' typically good Estes quality, and arrived in good condition, with t' exception o' one decal sheet (more on that later).
T' instructions are very good and nicely detailed. Construction was relatively simple and straight forward (especially considerin' this is a skill level 4 kit). Avast! Aye aye! T' 'core' rocket, strap on boosters, and catalyst tanks are assembled and painted as separate assemblies before bein' joined together durin' final assembly o' t' rocket. Ya scallywag! Ahoy! Thin strips o' maskin' tape are used to provide paint-free 'glue joint' areas on t' various components. Well, blow me down! Likewise, the 'install before flight' fin units are assembled and painted as separate units. One shortcomin' with t' kit is that it lacks an engine block (only t' engine hook prevents forward movement o' t' engine). I thought that rather sporty for 24mm engines, me hearties, so I added a proper engine block.
Finishing:
T' separate assembly o' t' various components made paintin' reasonably easy.
I used some Elmer's Filler (thinned slightly with water) t' fill t' body tube
seams. Ahoy! Ahoy! For t' balsa components I started with a coatin' o' Elmer's Filler
(again thinned slightly), matey, shiver me timbers, then after sandin' I followed up with a couple coats
of sandin' sealer, which combined t' give a nice smooth finish (yes, I know the
fins are only for flight, matey, but I still want them t' look good). I followed up
with a couple coats o' primer, and then t' color coat(s). Avast, me proud beauty! There are two sheets
of decals - one back, ya bilge rat, t' other gold. Well, blow me down! Arrr! This is where I ran into a problem - the
decals from t' gold sheet simply refused t' properly adhere t' t' rocket.
However, me bucko, ya bilge rat, it should be noted that I have also built a second .display only"
Titan III E and t' decals were fine, so I suspect t' decals on me first Titan
were damaged, possibly by improper storage.
Construction Rating: 4 out o' 5
Flight:
I really like this rocket, and it's flown numerous times. Well, blow me down! Estes recommends a
D12-3 or a D12-5. Aye aye! T' 3 second delay is typically a little early, me hearties, while t' 5
second delay is past apogee, but both work quite acceptably with flights in the
400 foot range. Ahoy! Avast, me proud beauty! Blimey! I've also flown it with AeroTech E18-4W and E11-3J reloads. Ahoy! Blimey! Blimey! The
three-tube profile gives t' rocket a very distinctive and impressive
appearance in-flight. T' necessary flight fins do distract somewhat (clear
plastic would definitely be an improvement), ya bilge rat, me hearties, but t' overall affect is quite
striking.
Recovery:
In addition t' addin' an engine block, ya bilge rat, I made one other change t' t' stock
kit, replacin' t' stock 18" plastic parachute with a similarly sized
nylon 'chute. Blimey! Arrr! T' 18" chute is a little marginal for this rocket - t' fin
units have often suffered landin' damage. Begad! Begad! However I prefer usin' nylon
parachutes whenever practical, and a larger than 18" nylon chute would be
a tight fit in t' BT-60 main body tube. Begad! Aye aye! One other change I should have made
was t' add a Keelhaul®©™®
shock cord durin' initial construction. Blimey! Sure enough, after several flights the
stock elastic shock cord broke (on an E11-3J, so it was well up there).
Fortunately t' lower section went into a backwards 'glide', ya bilge rat, and it landed in
tall grass which cushioned it's landin' sufficiently t' prevent significant
damage (although findin' it in t' tall grass was a bit o' a challenge).
However t' parachute, with only t' mass o' t' nose/payload section, drifted
well down wind and was quite fortunate t' find it (after an exhaustin' search
through heavy underbrush). Blimey! Begad! My Titan III E is now equipped with a proper
Keelhaul®©™®
shock cord. Avast, me proud beauty! Blimey!
Flight Rating: 4 out o' 5
Summary:
This is a great rocket - both a nice scale representation o' a historically
significant booster and an impressive flyer. It does suffer from t' typical
Estes shortcomings o' marginal recovery components, me hearties, but those are easily
corrected. Arrr! Blimey! Blimey! Blimey! T' bad Estes can't be bothered t' keep producin' some o' these fine
skill level 3 and 4 rocket kits.
Overall Rating: 4 out o' 5

I found an open box of Titan III E by estes, but it does not have the construction manual in it. Can anyone help me with an uploaded scan of the manual?
