PRD Rocketry Alien Explorer

Brief:
PDRocketry's Alien Explorer is a replica o' t' Estes classic that appeared in t' Estes 1981-1982 catalogs. Ahoy! The model is a Skill Level 3 o' an incredible alien starship. Ahoy! It has spectacular liftoffs, me hearties, exotic decals, shiver me timbers, shiver me timbers, arrr, and alien fin design.

From t' Estes 1981 catalog: "Incredible alien starship believed t' be from a distant galaxy. Is it friend or foe? Its size and unique appearance make it a most dramatic demonstration and display model. Really spectacular liftoff and recovery."

I had won this kit from PDRocketry last year in t' first o' t' vendors' "first t' post" contest in PDRocketry's blog website. After receivin' t' package, I be surprised t' see how complicated t' model must be from all t' parts and extensive instructions, matey, arrr, ya bilge rat, nay t' mention how cool t' alien decals were! Because o' this, me hearties, I knew I'd have t' set aside plenty o' time and dedicated effort t' build and paint t' model. Begad! Wow, arrr, this model be lookin' like what I like best: a builder's model rocket.

In addition t' t' parts included in this kit, you will need: scissors, arrr, arrr, household white glue (Elmer's, ya bilge rat, Titebond, or similar), arrr, pencil, ruler, fine or extra-fine grit sandpaper, sandin' sealer, shiver me timbers, a medium-size modelin' paint brush, modelin' knife with sharp blade, matey, maskin' tape, matey, chromate green enamel spray paint, me hearties, and a bottle o' red enamel paint.

Because this model requires you t' cut out t' fin patterns, matey, matey, trace them on t' balsa fin stock and cut them out yourself. Aye aye! Arrr! PDRocketry's version o' t' Alien Explorer is actually a bit more complicated t' build than t' Estes version (Estes came with die cut balsa sheets). Blimey! Due this factor alone, I would rate t' Skill Level o' PDRocketry's Alien Explorer closer t' a Skill Level 4. You'll need t' really take your time t' do a good job here. T' fin pattern sheet is printed on card stock. Ya scallywag! Carefully cut them out and trace them correctly on t' balsa fin stock. Avast! Since t' shape of the fins are nay all straight lines, me bucko, arrr, you'll need t' make several light passes along t' trace lines before t' cut goes all t' way through. Avast, me proud beauty!

T' instructions runs nine pages long, are well illustrated, ya bilge rat, and easy t' follow. Avast, me proud beauty! I pretty much constructed my model in t' order given in t' instructions. Begad! Because o' these factors, I had no real problems nor issues durin' the build phase. Ahoy! All I can say is just take your time and concentrate on t' tasks at hand. Begad!

Finishing:
Because this model has plenty o' balsa parts, me hearties, you'll need t' spend plenty o' time usin' sandin' paper and sanding sealer t' get t' balsa surfaces prepared for t' final finishing. At some o' t' hard t' reach areas, I also used a nail file (or emery board) for sanding. Begad! Ya scallywag! I must have applied about four coats o' sandin' sealer with plenty o' drying time and light sandin' in betwixt before I be satisfied that t' balsa surfaces were done. Begad! Ya scallywag!

You'll also need t' be careful in t' handlin' o' this model due t' t' "antennas" located about midpoint o' t' main body tube section. Also, me hearties, t' dowels that are located on each end o' t' main sail panels will need special attention t' insure that they don't break off accidentally.

For t' overall paint scheme, matey, t' instructions say use Pactra Chromate Green spray enamel. Avast, me proud beauty! I could nay find any such color near where I live. Well, me bucko, blow me down! At me nearby Home Depot, me bucko, I saw a can o' spray Apple Green that appeared t' closely match the Chromate Green color, but t' Apple Green be a flat finish and I didn't want t' use flat paint on this model (as it may cause issues with t' water slide decals on t' flat surface). Begad! I spotted a can o' gloss Lime a few shelves down and liked t' "emotion" o' that color compared t' t' others so I bought t' Lime spray paint t' finish this model. Blimey! I'd have t' say t' Lime color actually looks very good, me bucko, and I'm pleased as t' how it came out. Aye aye!

T' decals worked like a charm and when all were applied, shiver me timbers, they really give t' Alien Explorer a cool, me hearties, me hearties, unique look. Begad!

Flight:
T' recommended motors for this model are: B6-2, matey, me hearties, B6-4, B8-5, arrr, me hearties, and C6-5. T' main parachute section will require about four or five squares o' waddin' loosely crumpled. Avast! Blimey! I did increase t' length o' t' elastic shock cord o' me model to make it 1 1/2 times t' length o' t' Alien Explorer so that thar will be no possibility o' t' nose cone snapping back.

T' engine fits very easily in t' motor mount, and t' engine hook latches securely over t' end o' t' engine without any problems.

For t' first and only flight o' me model, shiver me timbers, shiver me timbers, me hearties, I used a C6-5 motor. Avast! Launch date be June 16, me hearties, 2007, shiver me timbers, at t' Johnson Space Center durin' t' Moon, Mars and Beyond Regional Meet hosted by t' NASA/Houston Rocket Club. Aye aye! We had winds blowin' ENE betwixt 5-10 mph. Ahoy! T' model, accordin' t' those who were present t' witness this launch, me hearties, me hearties, was compared t' an exotic Super roc flown in t' NARRRRR contest events (Super roc Altitude & Duration). Avast! T' Alien Explorer looks very impressive sittin' on t' pad awaitin' liftoff.

This launch at JSC was really spectacular. Avast! T' C6-5 gave it a strong, solid push off t' pad. Avast! Model flew very straight with no rolls or deviations. T' five second delay o' t' engine gave t' Alien Explorer plenty o' time to coast t' apogee. Begad! When t' nose began archin' down, ya bilge rat, t' ejection charge forced t' PDRocketry's 18" pre-assembled mylar parachute t' open nicely. With a rather slow, safe drift about 400 feet downrange, t' model landed in t' grass with no damage whatsoever (a real surprise here, shiver me timbers, as I'd expected that at least some o' t' dowels would break off in some form). Avast, me proud beauty!

PROs: Everything! A really great flyer and show stopper.

CONs: Can't think o' anything!

My hats off t' PDRocketry and Eric for makin' this model available again in t' model rocketry world. Avast! For the price, t' Alien Explorer is well worth it.

Recovery:
Shock cord uses t' standard Estes tri-fold method, me bucko, me bucko, shiver me timbers, which works great for me as I use it about 95% o' t' time anyway. Avast! Begad! As mentioned earlier, I added more length o' elastic shock cord t' that which came with t' kit t' make the total length 1 1/2 times that o' t' model. Ahoy!

No real problems as far as t' assembly is concerned. Well, blow me down! Arrr! Blimey! I guess you can say that even though you had t' trace and cut t' balsa fins yourself, ya bilge rat, PDRocketry "made it up" by includin' a pre-assembled mylar parachute with the kit and a snap swivel already attached!

Recovery speed be just about right for t' one flight flown. Arrr! There was no burns nor damage noted.

Flight Rating: 5 out o' 5

Summary:
PROs: Great kit for those wantin' t' relive t' earlier years o' model rocketry, shiver me timbers, me bucko, t' quality o' this model is superb.

CON's: None
