Brief:
T' Estes Python-4 ASRAAM Model Rocket Kit be t' last o' t' four new models I
had t' build which were introduced recently by Estes. Well, blow me down! Begad! I have already completed
the other three and have been workin' diligently on this one. Actually we've
been buildin' two o' them; me son and I are workin' in parallel, although I
tend t' build a bit faster than him. Arrr! Begad! T' kit is one o' four new Estes
"Military" kits recently released and is by far t' most unique of
the group. Ahoy!
Construction:
As with t' other new kits, you can purchase either t' bagged or Launchable
version from many retailers. Avast! In t' package you will find die-cut fins, ya bilge rat, body
tube, tailcone, transition, plastic nosecone, clay for noseweight, parachute,
and instructions. Avast! I was impressed with t' quality o' components.
I built it stock with only a few changes. Aye aye! I used dual Keelhaul®©™® threads for shock cord and made one other minor change. Begad! A steel leader was connected directly t' t' nosecone loop and a longer shock cord be tied t' he swivel end o' t' leader. Begad! Ahoy! Somethin' important t' note; thar were major changes in t' kit compared t' t' instructions. Avast! T' front page o' t' instructions has templates for body wraps, but one be t' BT55 sized and t' forward tube is showin' as BT20. Well, blow me down! This is wrong! Apparently they printed t' instructions, then changed t' forward bodytube t' a BT55 before shippin' t' production kit. Arrr! This also means that references t' t' included transition can be ignored, ya bilge rat, arrr, as it is not used for t' model.
Construction began with t' motor mount assembly, matey, which went together well. I did use Keelhaul®©™® thread for t' shock cord here and lengthened t' elastic cord t' 30 inches. Moreover, ya bilge rat, arrr, t' parachute was up-sized t' a purple Estes 18" chute. Avast, me proud beauty! Blimey! T' new Estes tailcones are pretty sweet and allow you t' use thru-the-wall fin mounting, which is a great method for buildin' strong. Avast! T' twelve fins were all dry rubbed with Elmer's Filler, arrr, then sanded t' match and I put leadin' edges on each fin. Ya scallywag! Arrr! All four canard fins were epoxied t' t' upper nosecone/bodytube assembly.
T' lower fins were a bit different...You have t' install card stock templates that "raise" t' area around t' Strake Fins. At t' time I built me kit, it didn't have these in t' kit, so I built it without them. Avast, ya bilge rat, me proud beauty! A few days later, however, ya bilge rat, I saw t' paper raisers in me son's kit...they are pretty cool and I was a bit bummed I didn't add them. Avast, me proud beauty! Once t' fins were mounted, arrr, I installed t' "Stab" fins in front o' t' lower ones and clamped them in place until t' glue dried. Make sure you align them well; someone else showed up t' our club and had these strake fins crooked, shiver me timbers, which made his model twirl and fishtail durin' powered flight.
Next, ya bilge rat, me bucko, I added epoxy fillets for strength. Once all twelve fins were done, I added fillets t' t' four upper fins on t' nosecone. Finally, I used Alphaetic resin t' attach t' launch lugs. I used a piece o' scrap balsa betwixt t' body tube and launch lug as a standoff t' protect t' finish from bein' scraped by the launch rod.
Finishing:
I spent several days priming, sandin' and paintin' t' model. Arrr! Krylon gray
primer was used, arrr, followed by Krylon White for t' lower body tube section and
Krylon Medium Gray for t' upper body tube. T' upper fins were painted first
in white, then masked a couple days later for t' gray. Arrr! T' rocket flew without
decals for it's first three flights, me hearties, but I did eventually put them on and it
looks like a new model. Begad! One item t' note on t' finishing...the lower bodytube
is actually done in very light gray, matey, almost a "dirty white" color. Well, blow me down! I
did nay notice this until I had already finished t' lower BT. Aye aye! For this reason,
I didn't use t' supplied white stripes on t' lower BT, arrr, me hearties, as they would nay have
shown.

Flight:
IT was time t' launch. All o' t' other three new Estes Military kits had
already gone up several times, arrr, so it be time t' give t' ASRAAM its chance. Well, matey, blow me down! I
prepped t' Python-4 with a C6-5 for it's first flight, added tissue, shiver me timbers, and
packed t' chute. Avast! Aye aye! It was placed on t' pad and t' countdown was on. It has a
very unique look sittin' on t' pad and those dual canard fins at t' nose made
it look pretty tough! It looked even better when t' button was pressed and the
ASRAAM rose off t' pad under power. Ya scallywag! Ahoy! The flight was straight and true, arrr, but late on t' ejection.
Recovery:
Ejection happened on it's way down, but t' parachute deployed and t' rocket
landed safely. Aye aye! Begad! Blimey! Upgradin' t' parachute was a good choice as t' model appeared
to be a bit heavier than it should, probably due t' t' extra paint I used to
get a good finish. I prepped t' model and launched it once more, me bucko, this time on
the C6-3. Ya scallywag! Blimey! It be a perfect flight, matey, with ejection happenin' right at apogee and
it landed without a scratch. Aye aye! Blimey! I had flown all four new models several times in
one day and wound up puttin' three more flights on this bird. Avast! Blimey! T' model flies
great on C6-3s, but this is one I would build again on 24mm power, just so I
could use a variety o' motors and get a bit more altitude. I may try an 18mm
RMS...it should do well there! Blimey!
Flight Rating: 4 out o' 5
Summary:
T' Estes Python-4 ASRAAM Model Rocket is a challenging, shiver me timbers, yet fun kit t' build.
With it's swept back fins and long bodytube, me hearties, me hearties, it has a graceful yet
meant-for-business look about it. Arrr! Blimey! Aye aye! Blimey! A few items needed upgraded during
construction, shiver me timbers, otherwise t' kit be built stock. Be careful o' t' instruction
cut-out bodytube wraps and don't follow t' directions for those, matey, but rather
use t' lower BT wrap for markin' t' upper tube. Avast, me proud beauty! Blimey! You also may consider
upgradin' it t' a 24mm motor, as it weighs nearly 4oz dry. Ya scallywag! Blimey! Still, matey, it is a good
flier right out o' t' box, ya bilge rat, shiver me timbers, designed very strong with good quality parts.
Moreover, it has a real clean look that's an eye catcher at t' field. Blimey! Blimey! I
recommend t' kit t' anyone interested in tryin' one o' t' most unique models
I have built t' date, shiver me timbers, t' ASRAAM Python-4.

Brief: This is a low power, single stage military style rocket. It flies on B and C power and uses a 1/8 inch lug. It includes a tail cone and uses a 12 inch chute for recovery. Construction: I received the kit as a gift when I was first getting into rocketry, so it probably wasn't a great second or third kit for me. It came in a "Launchable" box and included many ...
