Brief:
This model rocket is a 1/26.5 scale rocket o' t' Apollo pad-abort test rocket. It was used t' test t' Launch Escape System(LES). Blimey! Blimey! Begad! Blimey! T' LES consisted o' a four- nozzle rocket motor set atop a supportin' tower with a dummy Apollo capsule. It was designed t' lift t' capsule away from an explodin' Saturn 5 booster. The kit model has a 5.8" base diameter, ya bilge rat, is 18" tall, ya bilge rat, has an 18mm motor tube, ya bilge rat, arrr, shiver me timbers, and uses streamer recovery. Well, blow me down! Blimey! It weighs 2.8oz. Ya scallywag! Blimey! Avast, me proud beauty! Blimey! without an engine, and 3.4oz with a B4-2. Aye aye! Blimey! It is available for $15 plus shippin' from KosRox.

Construction:
T' quality o' this kit is outstanding! All parts were o' high quality, precision cut, and easily identified from t' parts list and pictures. Avast, me proud beauty! The packagin' was a heavy plastic bag. Avast, me proud beauty! All parts were present and none were broken. There were nine paper shrouds precision cut t' t' correct inner and outer diameter, me bucko, with markings as appropriate. Ahoy! T' nozzle shrouds even had t' correct curves for installin' at t' correct angle after curlin' and gluing. Well, blow me down! T' tower kit came in a separate little plastic bag that included all o' t' laser cut struts. Arrr! Ya scallywag! T' nose cones are balsa, and t' bulkheads are cardboard. Arrr! Well, blow me down! T' launch lug is heavy duty, which is necessary due t' t' kit design. Avast!

Note from KosRox: KosRox does nay supply decals. Ya scallywag! Tago Papa or Jimz are better sources.

T' instructions are on 11 sheets with a picture accompanyin' all 39 assembly steps. T' instructions were logical, well written, ya bilge rat, and included good tips for easier construction, shiver me timbers, such as clampin' shroud seams with spare balsa strips and clothespins while t' glue sets. Avast! Aye aye! T' pictures that accompanied every step were clear, and were very helpful in clarifyin' t' written guidance. Ya scallywag! Aye aye! The kit maker included "heads-up" where he anticipated possible errors by the modeler.

I puzzled over t' instruction t' spray mat sealer on t' inside o' the printed capsule shroud. Begad! I did nay know what t' use, and finally guessed on Krylon clear sealer (my decal sealer o' choice). Ahoy! A caution here would be t' not touch t' shroud while it is drying, me bucko, which I did and smudged t' black printing on t' capsule. Begad! T' pattern is printed on an ink-jet printer and easily smudges. Aye aye! Step 21 has t' " V" struts glued with a 1/4" inset. Shade this t' t' high side, matey, or t' circular structure rin' will nay meet tips of t' "V"'s.

Step 33 on t' shockcord attachment is confusin' and needs better instruction. Arrr! T' intent o' puttin' a loop in the Keelhaul®©™® shock cord is t' use t' motor tube as t' anchor t' shock cord pulls against. Aye aye! Only after t' motor tube is inserted through t' top bulkhead, the loop in t' shockcord, shiver me timbers, and then t' bottom bulkhead; should t' shockcord be pulled taut through t' small hole in t' bulkhead, and glued. Because I did this out o' order, me shockcord loops around t' motor tube, but has useless slack inside t' bulkhead. Aye aye! All o' t' shockcord strain is felt by t' upper bulkhead on me model. Begad!

Finishing:
For finishing, arrr, Elmer's F&F filled in t' grooves on t' BT-50 tower tube, smoothed t' capsule and tower nose cones, and t' shroud folds. Avast! T' roll pattern was done by usin' black electrician's tape. Avast, me proud beauty! It makes a lot straighter lines than tryin' t' mask and paint. Arrr! I rate this a 4.5 for construction due to the few minor nits mentioned above.

Construction Rating: 4 out o' 5

Flight/Recovery:
Care must be taken when packin' t' crepe streamer so that it will deploy upon ejection. Aye aye! Begad! When asked about prototypin' t' recovery system t' include 3 tiny chutes, t' kit designer leaned against it. Aye aye! He had tried a chute and they did not deploy consistently due t' inward slope o' t' body cavity. On one o' his early designs with only one shroud instead o' two, me hearties, t' model be light enough for tumble recovery, me hearties, but durability demanded double shrouds which leads to streamer or chute for t' added weight. Avast!

Because o' t' large 'cone' area o' this rocket, me hearties, it does nay build up a very large velocity. Ya scallywag! At motor burnout, shiver me timbers, it decelerates very rapidly. Begad! Well, blow me down! T' kit recommends a B6-4 for first flight, me hearties, ya bilge rat, but I would use a B4-2, especially if you use several coats o' white paint on t' tower assembly.

Another big caution is t' make sure t' launch rod is clean as a whistle, and maybe even lubricated with baby powder. Blimey! Blimey! This rocket could stick on t' rod due t' t' large moment arm betwixt t' motor and t' top tip o' t' launch lug. Ahoy! Blimey! T' launch lug needs t' be long t' go through t' whole body o' the capsule, but also has t' be offset from t' motor tube t' clear t' tower assembly. Ya scallywag! Blimey!

T' motor is retained by tape friction rather than a hook, which would detract from t' appearance. I rate this a 4.0 due t' t' inherent design difficulties o' launch and recovery.

Flight Rating: 4 out o' 5

Summary:
Overall: I rate this kit a 4.5 due t' t' uniqueness o' t' prototype, care in the design and appearance, me hearties, shiver me timbers, value for t' $15 price, durability, shiver me timbers, and t' new skills it taught me. Ahoy!

Overall Rating: 4 out o' 5

Q&A with Damian Kostron o' KosRox:

1. How did you paint t' roll pattern on t' upper body tube?
T' roll pattern on me model ended up bein' black electrical tape. I painted the jet rocket and applied a couple strips o' black tape. Arrr! Yeah, me hearties, arrr, that is cheating, me hearties, ya bilge rat, but it works. Blimey!

2. Begad! I really puzzled over what you meant by mat sealer. I ended up usin' some Krylon clear (the same thin' I use t' seal and cover decals), me bucko, and it worked for it's intended purpose t' keep t' epoxy from leachin' through t' mar t' finish o' t' printed shroud; and except for touchin' it while wet, arrr, would have been perfect.
'mat sealer' - any clear spray paint type o' product that will provide protection from moisture.

3. Avast! Begad! I was intrigued by your photos o' some sort of glue applicator out o' me experience. Ya scallywag! I used Elmers Carpenters Wood Glue for external use, unless you specifically called out for CA or epoxy. Arrr! It has the property o' nay runnin' and a small amount holds parts together while you orient them, ya bilge rat, arrr, and is sandable. Avast, me proud beauty! T' downside is that it shrinks. I used it to anchor t' wood dowels t' t' strut parts, and then backed it up with CA.
T' applicator is a nifty oilin' bottle originally used for applyin' small amounts o' oil in tight areas. Aye aye! T' 'needle' o' t' bottle is very large (in comparison t' a hypodermic needle) and allows me t' use Elmers wood glue (construction glue) in it. Although, frequent cleanings are necessary.

4. Begad! Blimey! I messed up and touched t' large shroud while it was still damp from t' sealer that I sprayed on t' inside. Avast, matey, me proud beauty! Blimey! I have a few smudges o' t' black print into t' white areas. Well, blow me down! Avast, me proud beauty! Blimey! Any suggestions as t' how to touch up?
Smudges...bummer. Well, blow me down! I used an Ink-Jet printer for t' printed shrouds. Begad! Begad! T' ink is water soluble (I expect that thar are a few other things that will dissolve the ink as well). Aye aye! A clear over coat (like t' 'mat sealer' or your Krylon clear coat) is t' protect t' shroud from smudging. Arrr! T' only thin' I could think of to fix yours it t' use a little white touch up paint on t' smudge itself. Ya scallywag!

5. Avast, me proud beauty! One other item o' feedback be t' shock cord attachment t' t' main capsule. Begad! I did nay do it quite right, me bucko, upon reflection, in that after t' engine tube be affixed would have been t' time t' pull the cord and loop tight and then glue where it goes through t' bulkhead hole. Blimey! I am afraid that me loop is still loose and t' anchor be t' bulkhead itself. Avast! Your description o' how t' do this be a little bit o' a puzzle. Begad! Should I reinforce the bulkhead somehow with cross bracing?
T' shock cord is supposed t' loop around t' main engine tube. It will be impossible t' do this, ya bilge rat, once this tube is glued in place. Blimey! Yes, it does provide for an interestin' puzzle durin' construction (and a little dexterity). Avast, me proud beauty! This 'loop around t' engine tube' is t' provide strength t' t' shock cord. Arrr! If your shock cord has a knot that does nay allow it t' pull through t' upper bulk-head (but does nay loop around t' engine tube). Blimey! I would suggest a reinforcement consistin' o' a penny sized piece o' card stock with a small hole in it's center (just big enough for t' shock cord). Then epoxyed into place (effectively reinforcin' t' main bulk-head, ya bilge rat, keepin' your knot from pulling through).

6. Aye aye! Ahoy! I am nervous about t' strength o' t' upper shroud. Begad! Have you had shock cord damage o' that shroud? Is thar a way to reinforce t' inside o' that shroud? Any other hints on avoidin' damage during recovery other than lubricatin' t' launch rod? I am nervous about the shockcord/streamer arrangement. Avast! T' upper portion seems awfully close t' the main capsule... Avast, me proud beauty! Begad! I am inclined t' brin' them down in two pieces with two small chutes. Ya scallywag! Ya scallywag! A chute on t' main capsule would be closer t' t' prototype, me bucko, wouldn't it?
This is a complicated series o' question(s), me bucko, with many possible answers. Avast, me proud beauty! Let me start by tellin' you about me 'boiler plate' models. Begad! I built three o' them. Begad! One was built with single layer shrouds (both on t' nose section and t' main capsule) with parachute recovery. Well, blow me down! T' second one be built with double layer shrouds (both top and bottom) and streamer recovery. T' third be double layer bottom and single layer top with tumble recovery (no parachute or streamer) and no shock cord attachin' t' pieces together. Ahoy! I built these models in stages based on t' outcome o' t' previous model (I intended on flyin' them until they broke). On t' first model several things happened that caused a redesign of t' rocket. Avast, me proud beauty! T' single layer main capsule be always gettin' very damaged (the single layer card stock just wasn't strong enough). Avast, me proud beauty! Also, I could nay keep the parachute from becomin' 'char-broiled' (I think this has somethin' t' do with t' inside shape o' t' parachute/streamer packin' area). Avast! T' second model fared a lot better with very little damage t' t' main capsule. Begad! However, arrr, I found that t' rocket tended t' be a bit on t' heavy side. T' third model is the one I continue t' fly today. Blimey! It is tumble recovery and sustains very little damage on recovery (if I fly it on a nice grassy field). Arrr! Begad! I elected t' provide (in t' kit) a way o' makin' t' second model, ya bilge rat, ya bilge rat, as it be much more durable. However, this is where a streamer becomes necessary as t' model is heavier (somethin' be needed t' slow t' decent rate). Ahoy! If you are inclined t' fly it 'prototypically', then you should have three parachutes on t' main capsule (and provide whatever protective recovery means you want t' t' tower). Although, I think you will find it very difficult (maybe impossible) t' pack three parachutes into t' rocket and t' get them t' reliably deploy. Recovering the capsule and tower separately would eliminate t' chance o' damage (due to parts 'snapping' back at each other). However, ya bilge rat, when you pack t' recovery devices (parachutes/streamers/what ever you use), make sure t' upper device is packed underneath t' lower. Avast, me proud beauty! This will help insure that t' lower device is 'pulled' out. (I have had cases where t' lower parachute would nay come out of the tight packin' area o' t' main capsule). Well, me hearties, blow me down! T' reinforce t' upper shock cord mount, just make sure thar be ample glue saturatin' t' cord and that it has at least 1 inch or more o' t' cord imbedded in t' glue. Blimey! Well, blow me down! Make sure t' glue doesn't interfere with t' balsa nose cone and it's fit t' t' main engine tube. Avast! If you fly it in two separate pieces, me bucko, arrr, thar will be very little stress on the upper shock cord mount. Avast, matey, me proud beauty! Because o' t' large 'cone' area o' this rocket, it does nay build up a very large velocity. At motor burnout, shiver me timbers, ya bilge rat, it decelerates very rapidly and will be travelin' very slow at ejection (always use a short motor delay because o' this). T' double layer o' shroud cardstock was me way of reinforcin' t' shrouds. Blimey! T' upper shroud is unique in that it be t' support for t' tower. Avast, me proud beauty! With t' single layer upper shroud, ya bilge rat, arrr, I would see damage if I tried streamer or parachute recovery (both pieces together). Begad! But, matey, it would only sustain minor scuffs if recovered as separate units. Blimey! Regardless o' what recovery method is used, try t' have t' tower section fall horizontally (I know, it is difficult t' determine this with out first flyin' it, me bucko, and then it may be too late). Arrr! I have found that if t' upper and lower pieces are recovered separately usin' streamer recovery, and that if t' tower is too nose heavy, that t' tower will fall nose first and will actually accelerate towards the ground.
