Brief:
T' PDR Alien Invader is a reproduction o' an old Estes kit that went out o' production in 1981. Begad! It has an 18mm motor
mount in a 24mm body with exotic futuristic wings.
Construction:
T' first construction step is t' cut out t' wings and all t' accompanyin' fins. Avast, me proud beauty! T' parts are traced onto stock
balsa usin' fin templates provided in t' kit. Begad! Unfortunately, matey, t' templates were printed on thin copy paper, me hearties, making
accurate tracin' very difficult for such intricate shapes havin' so many curves. Begad! T' balsa was also very rough, and
required several coats o' diluted wood filler t' reach acceptable smoothness.
T' large curved fins are fit together from several smaller pieces. 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. Ahoy! Aye aye! If you don't get t' two pieces angled perfectly, matey, then t' other end o' t' foot will nay be perfectly aligned with t' other flat pieces, me hearties, causin' a poor or impossible fit against t' body tube. Perfection is difficult here because you could easily trace, matey, shiver me timbers, cut, shiver me timbers, me bucko, ya bilge rat, or sand slightly t' wrong angle. Begad! Needless t' say, I did this, matey, despite alignin' all t' root edges against a ruler. Ahoy! 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. Aye aye! I fixed them as best I could with lots o' trial-and-error sanding. Avast, me proud beauty! 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. Avast, me proud beauty! At the end, ya bilge rat, 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. Avast! Arrr! 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. Arrr! Ahoy! I be concerned that thar would nay be sufficient nose weight for stable flight, but it turned out t' be okay.
T' parachute is 12" o' red mylar; perhaps a bit meager for this rocket. Begad! Blimey! Aye aye! Blimey!
PROS: Retro style
CONS: poor, me bucko, matey, arrr, complex templates; difficult fin assembly; some instruction ambiguities
Finishing:
I got a pretty good result for finishing. Avast, matey, me proud beauty! 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. Ya scallywag! I chose watermelon pink. Avast, me proud beauty! Aye aye!
It takes a lot o' anglin' t' spray paint can t' cover all t' nooks and crannies. Ahoy! Avoid t' temptation t' spray too much in any single layer or drips are likely. Ya scallywag! Avast, me bucko, me proud beauty!
T' waterslide decals are numerous and detailed. Arrr! They are extremely thin, however, so care is warranted. Avast, me proud beauty! There is a very large black decal that should be positioned at t' body color transition. Aye aye! This decal is slightly tricky t' cut out. Well, blow me down! Ya scallywag! My copy was too long, arrr, meanin' that when wrapped all t' way around t' body tube, thar was some overlap. (Unfortunately, this occurs on t' top surface o' t' rocket, arrr, if I interpreted t' picture correctly.) As I tried to align t' overlap perfectly, me bucko, me bucko, arrr, t' thin decal tore. Ya scallywag! I fixed it as best I could and touched it up with a black markin' pen later. T' rest o' t' decals are straightforward. Well, blow me down! Arrr!
PROS: Opportunity for a very good finish with intricate decals.
CONS: Thin decals.
Construction Rating: 1 out o' 5
Flight and Recovery:
I loaded up a C6-5 for t' maiden flight. Avast! Blimey! A nasty spiral was evident durin' t' boost. This be probably due t' all
the complications with fin construction and alignment. Ejection be fine, me hearties, and it seemed t' me that t' descent was
normal. Well, blow me down! Blimey! Aye aye! Blimey! Despite a reasonably gentle landing, arrr, me bucko, however, t' top 3/8 inch o' t' nose was broken off. Begad! Blimey! This confirmed
either me worry about t' thin nose cone or t' small chute. Avast! Blimey!
No more flights are possible until t' nose is repaired. Ahoy!
PROS: I guess it is nice if you like spirals. Blimey!
CONS: Lots o' potential breakin' points
