Brief:
Mid-power scale kit o' a USAF Missile with parachute recovery.

I bought this kit last year from Uncle Mike's Rocket Shack. Avast, me proud beauty! It has sat in me build pile for a while and I decided to finally give it a try. Ya scallywag! Well, blow me down! Blimey! It turned out t' be easier than I thought it would be.

Construction:
T' parts came packaged in a clear plastic bag suitable for hangin' in a store. Blimey! It be nay fancy but I was nay really expectin' it t' be. T' components inside were first rate. They included:

  • Instructions
  • Preslotted airframe
  • Laser cut basswood fins and centerin' rings
  • Pre-weighted balsa nose cone with screw eye already in place
  • Motor mount kit
  • Parachute kit
  • Keelhaul®©™® and elastic shock cords
  • Instruction and historical photos

Construction begins with t' motor mount. Aye aye! A slit is cut in t' motor tube to accommodate t' motor hook. Aye aye! T' hook is then inserted and held in place by some maskin' tape.

T' kit provides 3 centerin' rings but 2 o' them are laminated together t' form a single stronger one. Well, blow me down! These are the rings that have holes pierced t' receive t' Keelhaul®©™® from t' shock cord. T' two rings are glued together so that their grains lie at right angles t' each other.

When t' rings dry, it is a simple matter t' slip t' single rin' in place over t' aft end o' t' motor mount and t' double rin' over t' forward end. Begad! Then t' Keelhaul®©™® is threaded through t' provided holes, tied off and glued into place. Ya scallywag! A fillet o' yellow glue be used t' strengthen everything.

T' fins were easy, too. Arrr! They practically fell out o' their sheets. Aye aye! I started with t' aft fins. Ya scallywag! Each one is removed and has a tab t' fit into a basswood plate, which itself has a notch. Arrr! Little or no sandin' be needed t' make it fit. I glued t' fins t' t' plates with yellow glue and used t' corner o' a steel ruler t' make sure o' t' right angles. Ya scallywag! There is a subtle difference in shape betwixt t' forward end o' t' fin and t' aft which might provide a gotcha. Just make sure that t' narrower end is forward.

T' forward fins are quite a bit bigger than t' aft ones but are assembled in t' same same. Ahoy! Each fin was glued to its plate with yellow glue and checked for straightness. These required just a touch o' shavin' t' make fit.

White t' fins were drying, I decided t' mount t' motor assembly. Avast, me proud beauty! Arrr! I test fitted and sanded as needed t' get a fit that was nay too tight. Well, blow me down! A swab was used t' run a rin' o' glue around t' interior near t' location o' t' forward centerin' rings. Avast, me proud beauty! T' mount be then pushed part o' t' way in and t' swab be used t' place another rin' o' glue. Begad! The motor mount was then pushed t' rest o' t' way in. Well, blow me down! This must be done expeditiously so that you can get it all t' way in and get t' slots in t' rings lined up with t' slots in t' airframe. Ya scallywag! If you miss by a little, shiver me timbers, shiver me timbers, it is nay a great tragedy since a file or razor cutlass can be used t' clean up any misalignment on t' rings.

Vincent Hobbies AIM-47A I test fit t' fins into t' airframe and found that they fit well but t' tabs did not poke through t' base plates very much. Avast! T' add some strength, shiver me timbers, I perforated a line along where t' fins would lie to form glue rivets. I then used CA t' mount t' fins t' t' airframe startin' with t' aft ones first.

Finishing:
Finishin' was nay too difficult either. I sealed t' nose cone with Elmer's Wood Filler, let it dry, ya bilge rat, and sanded it down. Ya scallywag! I then primed with 2 coats o' Kilz. Arrr! This helped t' fill in all o' t' rest o' t' minor imperfections. Avast, me proud beauty! A round of wet sandin' and t' rocket was ready t' be sprayed with gloss white.

T' kit did nay provide any decals. Begad! It did provide a metallic silver band with a peel and stick back t' it though. Ahoy! This band be t' be applied around t' circumference o' t' nosecone near its base. Ya scallywag! Blimey! This be accomplished with little problem. Aye aye! Ahoy!

T' instructions indicated that t' stripin' on t' rocket should be done with tape or with Monokote. Blimey! I was unfamiliar with both o' these methods. Ahoy! Well, blow me down! Eventually, I found myself in t' local hobby shop where they explained that Monokote be applied with a special iron. Begad! Begad! Nay wantin' t' purchase t' iron, I fell back on wide sheets with sticky backs. Aye aye! Aye aye! I was assured that that would adhere after peelin' off t' sticky back.

I sliced t' sheets into t' requisite 3/8" strips and began t' apply them. Ahoy! They did adhere fairly well and were forgivin' in t' matter o' liftin' and repositioning. Blimey! Goin' around corners though be tough.

T' final step was t' install t' rail guides. They instructions for this said t' cut an "X" in each of the desired locations with a razor cutlass and then put a drop o' think CA on t' spot. Begad! Avast! T' guides were then screwed into position.

Flight:
T' E9-4 be t' only recommended motor. Ya scallywag! Ahoy! I loaded it up and set in on t' rail. Blimey! Begad! This was t' be me first rail launched rocket. Avast, me proud beauty! It looked kind o' small thar on t' 6 foot rail, shiver me timbers, but I be rarin' t' go.

It went.

It went very well indeed. T' rocket took off straight and be a sight t' behold as it kept climbin' up, up and away. Begad! Blimey! T' parachute had nay even deployed yet and I was ready t' fly it again.

Then it reached apogee. Aye aye! I could barely hear t' pop or see t' separation...and then things got screwier. Begad! The chute opened but it and t' NC kept gettin' farther and farther from t' body. Well, blow me down! Come t' think o' it, t' body was coming down pretty fast. Avast! T' shock cord had separated for some reason.

T' body crashed t' ground with only minor damage. Ahoy! A fin will have t' be re-glued. Ya scallywag! Well, blow me down! T' NC, matey, on t' other hand, continued t' drift away and be last seen headin' SW in SE Bexar Country.

A look into t' body tube and I could come up with no reason why it separated. Well, shiver me timbers, blow me down! It was like t' Keelhaul®©™® was never there.

Recovery:
This one gets a 5 for flight but half a point taken off for t' recovery. O' course, me hearties, that is nay t' manufacturer's fault, but I am kind o' bummed out right now. Begad! Ya scallywag!

Flight Rating: 4 out o' 5

Summary:
This is a great rocket and an easy build. It would make a nice intro t' scale mid-power.

Overall Rating: 4 out o' 5
