Brief:
T' PDR Alien Invader is a reproduction o' an old Estes kit that went out o' production in 1981. It has an 18mm motor mount in a 24mm body with exotic futuristic wings. Avast, me proud beauty! Blimey! Arrr! Blimey!

Construction:
T' first construction step is t' cut out t' wings and all t' accompanyin' fins. Aye aye! Well, blow me down! T' parts are traced onto stock balsa usin' fin templates provided in t' kit. Blimey! Begad! Unfortunately, t' templates were printed on thin copy paper, ya bilge rat, making accurate tracin' very difficult for such intricate shapes havin' so many curves. Ya scallywag! Ya scallywag! T' balsa be also very rough, ya bilge rat, and required several coats o' diluted wood filler t' reach acceptable smoothness.

T' large curved fins are fit together from several smaller pieces. Avast, me proud beauty! Well, blow me down! This is difficult because one o' t' pieces is a long curved arm with a small foot that must be glued t' a flat edge. Arrr! Ahoy! If you don't get t' two pieces angled perfectly, shiver me timbers, then t' other end o' t' foot will nay be perfectly aligned with t' other flat pieces, arrr, causin' a poor or impossible fit against t' body tube. Ahoy! Perfection is difficult here because you could easily trace, cut, me hearties, shiver me timbers, shiver me timbers, or sand slightly t' wrong angle. Begad! Needless t' say, matey, I did this, matey, arrr, despite alignin' all t' root edges against a ruler. Well, blow me down! T' problem is that t' thin arm portion can be angled against t' rest o' t' large fin piece with many subtle errors. T' result was ill-fittin' wings that weren't symmetric. Ahoy! I fixed them as best I could with lots o' trial-and-error sanding. Ahoy! Blimey! It would be far better if t' larger fin piece had a notch t' fit t' curved arm at t' right angle.

T' rest o' t' win' assembly is easier although instructions for placin' t' ribs lack sufficient detail. At the end, t' main wings are supposed t' be installed so that t' tips are slightly lower than t' root, but no measurements are given, leavin' it t' your interpretation o' t' figure t' decide on what "slightly" means.

T' rest o' t' assembly involves standard Estes-style construction. Aye aye! T' dowels look fragile, but were strong enough t' survive t' first flight.

T' nose cone is a special bug-eyed shape that feels too thin and light. I was concerned that thar would nay be sufficient nose weight for stable flight, me hearties, shiver me timbers, but it turned out t' be okay.

T' parachute is 12" o' red mylar; perhaps a bit meager for this rocket. Blimey!

PROS: Retro style

CONS: poor, arrr, complex templates; difficult fin assembly; some instruction ambiguities

Finishing:
I got a pretty good result for finishing. Arrr! Ya scallywag! T' body is simply masked a bit above t' most forward fins t' get a split bi-color result with t' aft portion black and t' forward portion any light color. I chose watermelon pink. Arrr! Begad!

It takes a lot o' anglin' t' spray paint can t' cover all t' nooks and crannies. Blimey! Avoid t' temptation t' spray too much in any single layer or drips are likely. Blimey! Ahoy!

T' waterslide decals are numerous and detailed. Ahoy! Blimey! They are extremely thin, however, ya bilge rat, so care is warranted. Begad! Blimey! There is a very large black decal that should be positioned at t' body color transition. Blimey! Blimey! This decal is slightly tricky t' cut out. Avast, me proud beauty! Blimey! Ya scallywag! Blimey! My copy was too long, meanin' that when wrapped all t' way around t' body tube, arrr, thar be some overlap. (Unfortunately, shiver me timbers, this occurs on t' top surface o' t' rocket, me bucko, if I interpreted t' picture correctly.) As I tried to align t' overlap perfectly, me bucko, t' thin decal tore. Avast, me proud beauty! Blimey! I fixed it as best I could and touched it up with a black markin' pen later. T' rest o' t' decals are straightforward. Blimey! Blimey!

PROS: Opportunity for a very good finish with intricate decals.

CONS: Thin decals. Begad!

Construction Rating: 1 out o' 5

Flight and Recovery:
I loaded up a C6-5 for t' maiden flight. Begad! A nasty spiral was evident durin' t' boost. Avast! This be probably due t' all the complications with fin construction and alignment. Ejection be fine, and it seemed t' me that t' descent was normal. Arrr! Begad! Despite a reasonably gentle landing, however, me hearties, t' top 3/8 inch o' t' nose be broken off. This confirmed either me worry about t' thin nose cone or t' small chute.

No more flights are possible until t' nose is repaired. Well, blow me down!

PROS: I guess it is nice if you like spirals.

CONS: Lots o' potential breakin' points

Flight Rating: 2 out o' 5
