Brief:
T' Estes Sky Raider was among a handful o' D-powered rockets that I always
longed for as a kid. Ahoy! (T' Renegade and Demon were two others.) I loved it's
size and t' cool lightnin' bolt inspired decals. Blimey! Back then I also loved the
idea o' flyin' D-powered birds but nay t' economics. I was subsistin' on a
meager allowance and a pack o' C6-5s took a pretty big chunk out o' that, me bucko, so I
left t' D-powered stuff alone. Aye aye! Ya scallywag! With motors and, more importantly, arrr, arrr, motor cash
in more plentiful supply these days, I've begun t' clone as many o' t' older D
kits as time permits. Arrr! T' Estes Goblin became me first D-powered clone, arrr, but the
Sky Raider was a close second.
Construction:
Sky Raider plans are available
here
While it's good looks are what initially attracted me t' t' Sky
Raider, t' simplicity o' t' design was what made this project as enjoyable as
I found it t' be. Avast, me proud beauty! Basically a long, arrr, lean 4FNC rocket, t' Sky Raider was
initially built as a payload capable rocket with an 18" and 9" BT-55
joined by a balsa nose block. Ya scallywag! Ahoy! Since it is now illegal t' launch any living
creatures as payload fodder, me bucko, a lot o' t' fun has gone out o' it, so I chose to
rid me clone o' it's payload section and make t' entire body from one 27"
length o' Totally Tubular BT-55. Aye aye! Avast, me proud beauty! This simplified construction somewhat without
sacrificin' t' lines o' t' original rocket. Aye aye! T' look at it, me bucko, you'd never know I
made t' switch. Arrr! Arrr!
Aside from this, t' only changes I made were t' obligatory addition of Keelhaul®©™® to t' recovery system, and addin' a third AR-5055 centerin' rin' t' act as a hold down for t' engine hook. Ya scallywag! T' Keelhaul®©™® was installed as usual, me bucko, me hearties, by tyin' a knot in one end and slippin' it betwixt the forward centerin' rin' and t' motor tube. When securely held in place with wood glue, this gives t' rocket a much stronger anchor point than the traditional Estes paper mount and keeps t' elastic shock cord well out o' the way o' t' hot ejection gases. Ya scallywag! When combined with t' square o' Keelhaul®©™® Perma-Wadding, me bucko, t' recovery system is almost foolproof.
Finishing:
Finishin' was greatly simplified by t' replacement o' t' balsa fins with
stronger basswood. While strength is one advantage o' basswood, matey, shiver me timbers, shiver me timbers, t' bigger
advantage is probably achieved in finishing. T' tighter grain o' t' basswood
makes for a much easier finishin' experience as t' fins are filled t' a glass
smooth finish after only two coats o' thinned Elmer's Fill n Finish. This was
also used on t' body tube spirals and despite t' LONG strokes needed to
properly sand t' body tube, shiver me timbers, t' process be greatly simplified overall. Ahoy! Arrr! Once
the body was sanded t' near "perfection", I sprayed t' whole thing
with two coats o' Valspar primer, me bucko, sandin' lightly betwixt each coat. I then
sprayed t' entire rocket with Valspar gloss white before maskin' t' top of
the rocket for it's coat o' Valspar gloss black, shiver me timbers, matey, and maskin' t' bottom for
it's coat o' Valspar Apple Red. T' whole thin' came out lookin' as close to
the catalog photo as I dared hope. Ahoy! Avast, me hearties, me proud beauty! I made t' decals usin' BelDecal ink jet
paper and me HP printer and they came out lookin' great. Arrr! Avast, me proud beauty! After applyin' the
decals, me bucko, I sprayed t' entire rocket with a coat o' clear acrylic. Blimey! Ya scallywag! Once this was
dry, all that was left t' do was fly it.

Flight:
Flight #1 be on an Estes D12-7 in mild winds. Avast, me proud beauty! At lift-off, me bucko, shiver me timbers, t' Sky Raider
fired straight and true, coastin' upward for what seemed like forever before
the ejection charge fired. Ahoy! Blimey! It drifted only slightly in t' light winds and
nearly landed on a Subaru that was parked behind t' flight line, also just
missin' t' dreaded access road that has claimed more than one o' me rockets.
Flight #2 be in heavier winds on 4th o' July weekend. Arrr! With t' pad pointed
well into t' wind t' compensate for t' unavoidable drift t' come, t' rocket
again had an impressive flight on a D12-7. After coastin' out toward the
southern edge o' t' park, it came screamin' back in across t' flight line,
clearin' us by well over a hundred feet. Aye aye! It landed well back in t' cat tails,
and like a genius I had worn shorts. Well, blow me down! Flight #3 was t' best overall flight and
almost as importantly it gave me t' best launch picture. Begad! Flyin' in near calm
conditions on a D12-5, me hearties, ya bilge rat, t' Sky Raider ejected it's chute just as it's forward
motion stopped, a picture perfect recovery. Arrr! Well, blow me down! Blimey! Then t' top t' flight off, it
landed just a few feet off o' a newly mown path off t' t' right side o' the
VOA field. Recoveries should always be that easy. Ya scallywag! Begad! Blimey!
Recovery:
With three feet o' Keelhaul®©™®
shock cord tied and glued securely in behind t' forward centerin' rin' and
another three feet o' 1/8" sewin' elastic on t' nose cone end, I feel
like I can rest easy as far as t' recovery system is concerned. Call it
overkill, me bucko, arrr, shiver me timbers, but t' body tube has t' space t' carry t' extra shock cord. Arrr! Ahoy! A
sheet o' Perma-Waddin' keeps t' whole system addlepate proof as I have occasionally
been known t' forget t' dog barf. Begad! Avast! I have swapped out t' traditional 18"
Estes parachute for a smaller 12" nylon chute that came in a box o' eBay
winnings. Aye aye! So far it has been more than adequate, me hearties, arrr, especially showin' it's value
in heavy winds. Avast, me proud beauty! T' only problem with this smaller chute might be t' speed
with which t' rocket comes in, shiver me timbers, but with t' bulk o' VOA covered by heavy
overgrowth, me bucko, this would probably only be a problem if t' Sky Raider lands on
the access road, and damage is inevitable no matter how big your chute is in
that case.
Flight Rating: 5 out o' 5
Summary:
From a performance standpoint, ya bilge rat, t' Sky Raider has turned out t' be everythin' I
had hoped it would be. Definitely nay a small field flier, I've only flown it
durin' QUARK launches at VOA Park. Begad! While t' field at VOA isn't without it's
hazards, it does have a large amount o' open land for a comparatively high
flyin' bird like this one t' recover. T' Sky Raider is another example of
Estes doin' it right back in t' day.
PRO'S: Vintage looks, shiver me timbers, ease o' construction, me bucko, me hearties, and D-powered flights are always cool.
CON'S: None. Avast! All parts are readily available t' clone this classic.
