Brief:
This be t' Das Modell Aggregat-4 (A-4) Peenemünde V2. Avast! It is designed by Thorwald Peterson o' Noris Raketen's Das Modell in Nürnburg, Germany. Avast, me proud beauty! It is a single-stage Skill Level 3 rocket kit that is nay available for sale in t' United States. I imported it from a hobby shop in Great Britain several years ago, me hearties, along with t' Saturn V, Space Shuttle and Phoenix kits. Blimey! Aye aye! T' finished V2 model stands at 16" tall. Ya scallywag! T' A4 V2 is a semi-scale model based on t' Von Braun vengeance weapon Peenemünde circa 1942.
Construction:
T' kit came in an attractive full color cardboard box and was complete. It has a 1 7/8" airframe, me hearties, unique shaped plastic nose cone and boat tail, 18mm motor mount with clip, ya bilge rat, fiberboard fins, matey, clay nose weight, 30" plastic chute, shiver me timbers, two foot piece o' tubular nylon, ya bilge rat, a bag o' cotton wadding, German and English instructions, a UKRA checklist, and a decal.
Bein' a last minute modeler at times, ya bilge rat, I pulled this kit out o' me rocket closet just 48 hours before needin' it ready t' fly. Houston's NHRC (NASA Houston Rocket Club) had a very unique event scheduled for Saturday September 18th called t' Wacky Wockets/V2 Contest at NASA's Johnson Space Center in Clear Lake, matey, Texas (near Houston). Ahoy! I opened t' box at about 8AM on t' previous Thursday t' 16th, laid everythin' out and got t' building. Blimey! Ya scallywag! While thar were two sets o' instructions (as this was packaged for sale in t' UK), I decided t' use t' German ones just for grins. Avast, me proud beauty! Begad! T' instructions are so well illustrated that you don't really have t' be able t' read them (and I do nay speak or read German.)
In t' first step o' buildin' t' rocket, shiver me timbers, I made a mistake. Well, blow me down! I adhered t' airframe onto t' boat tail without realizin' that it would have been a lot easier t' build and install t' motor mount first. Begad! This was entirely me fault as I started with t' wrong step and it did create a challenge durin' t' build. Blimey! In order t' adhere t' top rin' o' t' motor mount t' t' inside o' t' boat tail I had t' make a paper syringe out o' a cardboard plate and sort o' pour-squirt some 30 minute epoxy down into t' motor mount by goin' through t' top o' t' airframe. Blimey! This be very tedious but ended up turnin' out perfect.
T' fiberboard fins were pre-cut and appeared as if they would conform t' t' shape o' t' boat tail but they were a little off. Ya scallywag! I had t' use some 240 grit sandpaper t' re shape t' root edges but this didn't really take long.
T' recovery system was designed t' use a two foot long piece o' 1/8" tubular nylon secured t' a cardboard motor mount type rin' which also serves as a mini baffle. I used an X-Acto pin t' punch two holes into t' rin' and installed a double loop o' 50# Keelhaul®©™thread so that if one side ever burns through I will have a backup. Well, arrr, blow me down! Blimey! Blimey! Blimey! While t' tubular nylon be a nice feature, unfortunately it be too short. Blimey! Blimey! Blimey! Blimey! I added an eight foot long 1/8" sewin' elastic shock cord that can be easily replaced. T' plastic parachute that came with t' model was a 30" Estes type with German print. Ahoy! Blimey! Blimey! Blimey! I kept it as a novelty and selected an 18" red Top Flight Recovery nylon rip stop chute.
Finishing:
Finishin' this model was simple. T' fiberboard fins do nay need t' be sanded or sealed so I just shot it with a quick coat o' white primer, me hearties, then a few coats o' gloss white. I may hand paint or tape off and spray paint t' scale black panels later.
Construction Rating: 4 out o' 5
Flight:
T' first flight be at NASA's Johnson Space Center in Houston Texas as part o' t' 2004 Wacky Wockets / V2 contest. Begad! I used t' only motor recommended by Das Modell, me bucko, which be t' C6-3. Begad! Very nice high boost and twisted quite a bit.
Recovery:
Perfect deployment and landed on a giant avast bail about 400 feet west o' t' pad.

Summary:
This is a unique V2 which is fairly simple t' build, ya bilge rat, arrr, has nice quality components, arrr, me bucko, and it's rare! Chances are no one else in your club has one or has ever seen one. Aye aye! It will draw some comments. Avast, me proud beauty! Unfortunately these are extremely hard t' get. Begad! Avast, me proud beauty! I have wanted t' purchase more Das Modell models and have emailed Das Modell many times but have never received a response. Avast! Ya scallywag! I even called them in a three way conversation with a friend in Germany speakin' for me t' ask if I could purchase more, but I was told t' stop by their shop. Apparently they do nay export their kits t' t' United States. Begad! Well, blow me down! As I will be in Nürnburg, shiver me timbers, Germany in January, I do plan on goin' by their store. Blimey! Das Modell even produces engines, arrr, ya bilge rat, ya bilge rat, like t' D7-5, which are nay available in t' US either. Avast, me proud beauty! I plan on pickin' up some more kits and motors so I can ship them back t' me home in Texas.
Overall Rating: 4 out o' 5
I have more time into this build than what I would like t' admit. Blimey! I worked on it off and on over a 10 hour period, arrr, startin' with Gel CA for t' motor mount and then 28 minute CA for t' fins. Arrr! Altogether it took over 4 hours t' build.
I was reminded o' a valuable lesson durin' this build and that is don't procrastinate. Begad! Arrr! I should have started this model at least a week before wantin' t' fly it, me hearties, nay two mornings before. Avast, me proud beauty! I had a major nightmare happen when finishin' up. Avast, me proud beauty! I be usin' an Estes fin alignment guide and after gettin' all t' fins on with t' 28 minute epoxy along with some small brushed fillets, I noticed that a drop o' epoxy was holdin' t' motor clip in t' open position as I be usin' a spent motor case t' cause t' rocket t' stand at t' proper height. Avast! Ya scallywag! Fearin' that it would dry that way I carefully removed t' rocket from t' alignment guide, ya bilge rat, removed t' engine and one by one t' fins started t' slide off. In a panic I laid t' fins on some wax paper, cleaned up t' mess, shiver me timbers, me hearties, stuck a piece o' wax paper betwixt t' clip and airframe, me hearties, stuck t' motor back in, arrr, matey, put t' rocket back on t' stand/alignment guide and put t' fins on a second time as t' epoxy was startin' t' cure. This be frantic and would nay have been such a big deal if I did nay want t' have t' model ready for paint t' next mornin' and ready t' fly t' day after.
T' finished product is a nice strong little V2 that I feel good about. Aye aye! Aye aye! It looks great and if I can figure out how t' pronounce it's correct name I am sure it will impress other club members on t' field. Blimey! Ya scallywag! :) I will most certainly build and fly more Das Modell kits and if you can find one, I highly recommend them.
