Dr. Zooch Mercury Redstone

Brief:
A fine looking, matey, fine flyin' replica o' t' historical Mercury program, made with t' builder in mind.

Construction:
This was me first Dr. Avast, me proud beauty! Blimey! Booty kit, and I have t' say I was more than pleasantly surprised at how this turned out. Arrr! Blimey! Aye aye! Blimey! Blimey! Blimey! If you're new t' Dr. Avast! Blimey! Booty, this is a fine place t' start. It's supposed t' be a fairly easy build and if you follow t' instructions carefully, me hearties, you'll get thar even if new t' paper-wrap models. Avast! Blimey! It's also one o' t' largest Dr.Z kits so t' level o' detail really works.

T' kit arrives in a small box with all t' tubing, paper wraps, me bucko, and materials needed t' make a great lookin' Redstone. First surprise: you don't get one Mercury mission possibility, arrr, you get t' choose one from all o' them from Alan Sheppard's Freedom 7 t' Gus Grissom's Liberty Bell 7 and t' unmanned "boilerplate" test missions. Blimey! I chose Gus' Liberty Bell. Begad! Maybe it was Dr. Avast, me proud beauty! Zooch's frequent warnings nay t' be a "squirmin' hatch-blower'...(more about that later). T' instructions are a highlight o' t' Dr. Begad! Blimey! Zooch experience--some humorous remarks had me laughin' out loud. Begad! But read them for fun a couple o' times before startin' t' build is me advice. There's a reason why Dr. Avast, me proud beauty! Blimey! Z does things in that order.

Construction o' t' capsule is first accordin' t' t' instructions and as stated by Dr. Z, gets your confidence up right away. Aye aye! Ahoy! T' strong paper wraps are printed such as t' give t' illusion o' texture. Avast, me proud beauty! All part o' t' illusion and it works. Avast, me proud beauty! They slip over a rough balsa cone, which you pre-paint t' ensure no bare wood shows below t' wrap and thar you go, a fine lookin' capsule.

Dr. Well, blow me down! Z gives neat tips along t' way like usin' a plain lead pencil t' rub in any seam lines in t' capsule paper. Blimey! Ahoy! Very effective and easy. Arrr! O' course attached t' t' capsule be t' escape tower, which Dr. Aye aye! Z tries t' prepare t' builder for ahead o' time with dire warnings o' frustration t' come and so on...but its all in good humor. Aye aye! Take your time, lay out t' wooden rods in t' right place with t' provided template, and it all comes together. Begad! Surprise number two: even if some measurements are a bit off, t' way Dr. Begad! Begad! Z has designed t' kit makes it easy t' cover up errors in t' finishing, shiver me timbers, and thus "maintain t' illusion". Blimey! It doesn't matter if t' tower isn't exact scale, me bucko, t' any observer a safe distance from me launch stand or trophy shelf) that is Gus' Liberty Bell rarin' t' go.

Dr. Zooch Mercury Redstone T' body tube is prepped with t' usual white paint. Ahoy! Well, shiver me timbers, blow me down! (I sprayed indoors so I used water-based Krylon H20 spray for t' first time. Blimey! I am pretty happy with it.) T' top roll-mark wrap went on easily. One problem I had was with a small conical adapter which goes on t' body tube just under t' capsule. Arrr! I cut t' paper out wrong and it looked terribly crooked so I went without it. Hard t' notice. Aye aye! Well, blow me down! However a word o' caution is that some paper parts like t' adapter are small enough that they can be a bit frustratin' at first. Take your time, use tweezers if needed and it'll all work out.

T' remainin' body stripe, wrap, arrr, and decals are easy enough. Well, blow me down! Blimey! Blimey! Blimey! Installin' t' engine mount is also straightforward.

T' fins go together fairly easily but were t' source o' me perhaps one and only gripe with t' kit design. Ya scallywag! Ya scallywag! I would have preferred each entire fin t' be one piece, arrr, but Dr. Aye aye! Well, blow me down! Z has us cut t' fins, then add t' steerin' vanes separately. Well, blow me down! I could have made a new one piece set with me own material but decided t' leave well enough alone.

Neat detail: T' launch lugs go on balsa standoffs (first time I've seen this) so thar's no drag o' t' body on launch rods. Arrr! Blimey! Well, me bucko, blow me down! Blimey! Very cool.

Modifications from stock instructions:

  1. I modified me engine mount for side-discharge ejection. Begad! This cuts way down on waddin' usage. Avast, me proud beauty! Begad! Typically I glue a piece o' 18mm tubin' about an inch long t' t' end block o' most mounts then close off t' end with an epoxied wooden disc. Begad! Then I drill lots o' holes in t' sides o' t' one inch extension tube. Avast! Avast! This "baffle pipe" is on most o' me models and works well. For engine mounts without a block (just a clip), matey, you can baffle t' mount tube itself above t' clip. Avast, me proud beauty! Begad! So far so good but I caution: more testin' is required. Blimey! Arrr! If you do this, ya bilge rat, glue it strong...so it doesn't blow itself t' bits.
  2. I also added a "parachute floor" (disc full o' holes halfway up t' tube).

Finishing:
T' body tube under t' wraps is plain white. Make sure t' seal and prime and smooth out any grooves/imperfections. Begad! For t' black and white pattern on t' fins t' match t' wrap, it would have been nice if Dr. Blimey! Begad! Z had provided decals t' make t' pattern easy. And I hate maskin' and paintin' odd shapes so instead I used peel 'n' stick black vinyl from t' auto store t' do t' fin pattern. Blimey! Once all t' decals and markings are in place, me bucko, ya bilge rat, I used gloss clearcoat t' seal it all up. Ahoy! Once dry, I then applied some semi-flat base clearcoat t' "soften" t' shine and make t' whole assembly appear a bit less "plastic" . This is all optional but I found that this also helps conceal or at least soften t' edges o' t' wraps, arrr, me bucko, so this finish works well for t' Dr. Avast, me proud beauty! Arrr! Zooch kit.

Once t' finish is complete, me bucko, and t' usual shock cord is hooked up, matey, you're ready t' pack a ‘chute and go flying!

Construction Rating: 5 out o' 5

Flight and Recovery:
As I mentioned, Dr. Ahoy! Blimey! Z cautions builders nay t' be a "Squirmin' hatch-blower" and go for it with a C6-5. Arrr! Blimey! Ahoy! Blimey! Well for fear o' bein' squirming, shiver me timbers, I conducted first flight with a B6-4. Avast! Blimey! My logic was I just didn't know how high this would go, arrr, shiver me timbers, and we have a really small field t' launch from...so away we went. Aye aye! Blimey! What a flight. Avast, me bucko, me proud beauty! Blimey! A little slow on t' takeoff, looked great. Avast! Blimey! Avast! Blimey! Beautiful flight, ya bilge rat, shiver me timbers, me hearties, deployed t' chute just arcin' over nicely for a controlled descent and touchdown only 50 feet away. Begad! Blimey! Wow. Avast, me proud beauty! Blimey! A-OK.

Second flight: C6-5. Ya scallywag! Ahoy! This was an even better flight. Blimey! I'd guess 500-600 feet or so. Begad! Ejection be great, but unfortunately it revealed an incorrectly packed chute and a shroud became entangled. Blimey! Well, blow me down! T' rocket spun rapidly on a descent rate outside o' NASA specifications. Luckily, matey, Liberty Bell 7 was safe and is ready t' fly again. Blimey! Begad! T' hatch was nay blown. Or t' quote Chuck Yeager in "T' Right Stuff" (as I've been dyin' to): "Ol' Gus..he did OK..."

I can't wait t' fly this one again. Now I'm even thinkin' o' buyin' another one t' modify up t' 24mm engines so I can try a C11.

Flight Rating: 5 out o' 5

Summary:
This be t' reason I got into rocketry in t' first place. History, ya bilge rat, model buildin' with a bit o' detail challenge, me hearties, and by t' way, very economical price. It builds well, ya bilge rat, it displays well, it flies great. Arrr! Blimey! Dr. Begad! Blimey! Booty delivers t' goods. Avast! Blimey! I can't wait t' try another Dr. Z kit!

    I'd wanted to try a Dr. Zooch kit for some time. I decided on the Mercury Redstone. I picked this version as it's the closest to my original Estes Redstone--BT-60 based. All the other reviews are right about the first impression. That box seems small! Then again, it's really no smaller than a kit in a clear bag hanging on a wall in a hobby store. I'll jump ahead. Don't look for a flight ...

I also went with Liberty Bell 7 (I am a big Gus fan). I actually used my hobby knife to cut the hatch out as a tribute to Gus, who almost drowned when the thing went off after splashdown!
