Brief:
T' Estes Sky Raider be among a handful o' D-powered rockets that I always longed for as a kid. Begad! (T' Renegade and Demon were two others.) I loved it's size and t' cool lightnin' bolt inspired decals. Back then I also loved the idea o' flyin' D-powered birds but nay t' economics. Blimey! I be subsistin' on a meager allowance and a pack o' C6-5s took a pretty big chunk out o' that, so I left t' D-powered stuff alone. Ahoy! With motors and, more importantly, motor cash in more plentiful supply these days, I've begun t' clone as many o' t' older D kits as time permits. Avast, me proud beauty! T' Estes Goblin became me first D-powered clone, matey, but the Sky Raider be a close second. Begad!

While it's good looks are what initially attracted me t' t' Sky Raider, shiver me timbers, matey, t' simplicity o' t' design was what made this project as enjoyable as I found it t' be. Basically a long, 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. Since it is now illegal t' launch any living creatures as payload fodder, a lot o' t' fun has gone out o' it, matey, matey, ya bilge rat, 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. This simplified construction somewhat without sacrificin' t' lines o' t' original rocket. Begad! T' look at it, me hearties, me bucko, you'd never know I made t' switch. Begad!

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. Begad! T' Keelhaul®©™® was installed as usual, by tyin' a knot in one end and slippin' it betwixt the forward centerin' rin' and t' motor tube. Ya scallywag! When securely held in place with wood glue, shiver me timbers, 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. Begad! When combined with t' square o' Keelhaul®©™® Perma-Wadding, 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, shiver me timbers, t' bigger advantage is probably achieved in finishing. Blimey! 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. Well, blow me down! Arrr! This was also used on t' body tube spirals and despite t' LONG strokes needed to properly sand t' body tube, me bucko, t' process be greatly simplified overall. Once the body was sanded t' near "perfection", I sprayed t' whole thing with two coats o' Valspar primer, sandin' lightly betwixt each coat. Ahoy! 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, and maskin' t' bottom for it's coat o' Valspar Apple Red. Avast, me proud beauty! Avast! T' whole thin' came out lookin' as close to the catalog photo as I dared hope. Aye aye! Aye aye! I made t' decals usin' BelDecal ink jet paper and me HP printer and they came out lookin' great. Blimey! After applyin' the decals, me bucko, I sprayed t' entire rocket with a coat o' clear acrylic. Blimey! Once this was dry, all that was left t' do be fly it.

Flight:
Flight #1 was on an Estes D12-7 in mild winds. Begad! At lift-off, t' Sky Raider fired straight and true, me bucko, ya bilge rat, coastin' upward for what seemed like forever before the ejection charge fired. 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 was in heavier winds on 4th o' July weekend. Begad! Avast! 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. Avast, me proud beauty! After coastin' out toward the southern edge o' t' park, me hearties, it came screamin' back in across t' flight line, clearin' us by well over a hundred feet. Begad! Begad! It landed well back in t' cat tails, and like a genius I had worn shorts. Avast! Flight #3 was t' best overall flight and almost as importantly it gave me t' best launch picture. Aye aye! Flyin' in near calm conditions on a D12-5, ya bilge rat, t' Sky Raider ejected it's chute just as it's forward motion stopped, me bucko, a picture perfect recovery. Then t' top t' flight off, arrr, it landed just a few feet off o' a newly mown path off t' t' right side o' the VOA field. Aye aye! Recoveries should always be that easy. Begad!

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. Avast, me proud beauty! Arrr! Call it overkill, ya bilge rat, but t' body tube has t' space t' carry t' extra shock cord. Begad! A sheet o' Perma-Waddin' keeps t' whole system addlepate proof as I have occasionally been known t' forget t' dog barf. 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! Aye aye! So far it has been more than adequate, especially showin' it's value in heavy winds. Ahoy! T' only problem with this smaller chute might be t' speed with which t' rocket comes in, ya bilge rat, shiver me timbers, but with t' bulk o' VOA covered by heavy overgrowth, 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, t' Sky Raider has turned out t' be everythin' I had hoped it would be. Avast! Definitely nay a small field flier, me bucko, arrr, I've only flown it durin' QUARK launches at VOA Park. Ahoy! While t' field at VOA isn't without it's hazards, me bucko, it does have a large amount o' open land for a comparatively high flyin' bird like this one t' recover. Well, me bucko, blow me down! T' Sky Raider is another example of Estes doin' it right back in t' day. Avast! Begad!

PRO'S: Vintage looks, matey, ease o' construction, arrr, arrr, and D-powered flights are always cool.

CON'S: None. Ahoy! Avast! All parts are readily available t' clone this classic.
