Brief:
My first attempt at a plastic model conversion (PMC). Arrr! It is a 1/35 scale V2
rocket by Dragon that be easy to
build and flies well.
Construction:
T' plastic kit comes with three sprues, shiver me timbers, detailed instructions and decals
(except me kit didn't contain t' decals). Since I wanted t' fly this kit and
not have it sit on a shelf, I was nay too worried about t' missin' decals.
T' kit itself is for a V2 rocket sittin' on a launch pad. Aye aye! This means that you can get rid o' most o' t' parts straight away. T' parts o' t' kit you need are:
To covert this t' a flyin' rocket, you will need:
To build t' kit I used:
All t' plastic parts snap off t' sprues easily and contain a lot of detail. Arrr! Avast, me proud beauty! T' panels o' t' V2 are marked and t' vent rin' is there, ya bilge rat, which is a nice touch as it is absent from some kits.
T' first thin' t' do is t' make the motor mount. Begad! Blimey! Ya scallywag! Blimey! T' A5 plug has t' be cut down t' accept a BT-50. Aye aye! Blimey! Avast! Blimey! Usin' t' rotary tool, matey, this was easy t' do as t' rough edges were smoothed down usin' a grindin' disk. Arrr! Blimey! Do nay glue t' BT-20 t' t' plug yet.
Glue t' body tube halves together then t' two nose cone parts together. CA gel works best as it bonds smartly but does nay run like normal CA glue. Glue t' fins t' t' lower body tube. Avast! Avast, me proud beauty! [Note: T' fins have an attachment rod on t' lower part. Avast! Begad! This is t' attach t' V2 t' t' base stand. I removed these with t' grinder.]Glue t' middle and upper body tubes together. Begad! Glue the A5 vent rin' t' t' lower body tube.
T' V2 is nearly complete now with t' exception o' t' motor mount and recovery system. Ya scallywag! However, arrr, I did nay want an ejection charge goin' off inside the V2 for a number o' reasons:
To get around this, me bucko, I decided t' have t' motor mount tube runnin' the entire length o' t' rocket with a plug fixed t' t' top o' t' V2. Aye aye! Aye aye! This would allow t' ejection charge t' blow off t' top half o' t' V2 (splittin' it at the vent ring) with all t' hot gas ejectin' clear o' t' recovery system and plastic.
T' plug that be glued into t' top of the rocket was made out o' t' bottom half o' an 18mm motor. Avast! This was cut using a cuttin' disk and cleaned up. Blimey! I then slid t' plug into one end o' t' BT-20 and applied epoxy t' t' end o' t' plug. Next, arrr, ya bilge rat, I slid t' BT-20 up through the bottom o' t' V2 until t' 18mm engine case plug touched t' top o' t' V2. After 30 seconds t' epoxy had set enough for me t' remove t' BT-20, leaving the plug in place. Ya scallywag! [Note: Use t' A5 motor mount rin' made earlier t' ensure that t' BT-20 is aligned correctly.] Make sure t' glue is set before the next stage.
Slide t' A5 motor mount rin' over t' BT-20 and then offer up t' tube inside t' V2 so t' top o' t' BT-20 slides over t' plug. Aye aye! Blimey! Next slide the motor mount rin' up t' BT-20 until it sits flush with t' bottom o' t' V2. When you are happy that everythin' is aligned, glue t' motor mount ring, shiver me timbers, BT-50 tube and V2 together. Begad! Finally, shiver me timbers, trim t' protrudin' BT-20 down until it is flush with t' aft o' t' A5 mount.
Even though t' top o' t' nose has yet t' be glued on, matey, leave this off for now as t' model may need weightin' at t' top t' raise t' CG. I decided to have t' rocket recover in two halves. Arrr! There is no real reason for this and you could easily use t' normal Estes style recovery on an 18inch parachute.
T' light top half o' t' V2 had an Estes card shock cord mount and two foot length o' elastic attached. Well, blow me down! (I normally avoid this like t' plague, as I have lost too many rockets t' elastic burn out). There should be no heat anywhere near t' cord so thar isn't any need for Keelhaul®©™®. I used an Estes 12inch plastic parachute with a snap swivel. Ahoy! T' bottom half had a snap swivel glued and Keelhaul®©™® tied t' t' BT-20 then a two foot length o' elastic with a 12inch parachute and swivel be used.
A launch lug was glued t' t' middle body tube o' t' V2. Begad! This spoiled the look a bit and I suppose that I could have used an internal lug, but that would have taken a lot o' time. Avast, me proud beauty! Aye aye! Blimey!
Finishing:
I went for a camouflage pattern instead o' t' black and white scheme. Ahoy! I used
spray can paint and went for an original design that I rushed. Well, blow me down! Arrr! Blimey! It be nay the
best finish that I've done. Ya scallywag! Begad! Blimey! This is me first PMC I didn't want t' spend hours
finishin' t' rocket t' see it possibly destroy itself first flight. Well, blow me down! Blimey! Also, I
sprayed t' body tube fluorescent green so I could see it in t' grass because
camouflaged rockets are hard t' find! Blimey! As I mentioned above, thar should have
been decals with t' kit but me box did nay have any.

Flight:
Before preppin' for flight, shiver me timbers, I did a swin' test t' check for stability.
Surprisingly t' rocket needed no nose weight t' be added for stability so the
top o' t' V2 was CA glued into place. At over six ounces, arrr, this rocket should
be flown on a D motor, however, me hearties, an 18mm motor be t' biggest I can use. Ya scallywag! A C6-3
should lift it.
For t' first flight on March 13, 2006, matey, two parachutes were dusted and packed with t' top parachute below t' bottom parachute. Wind conditions were not good as thar were gusts over 20mph. Blimey! Avast, arrr, me proud beauty! Blimey! Normally I would nay fly in these conditions, but I was eager t' see me new project in t' air. Well, blow me down! A standard Estes 3mm rod was used. Well, blow me down! Blimey! T' V2 lifted slowly off t' pad, on a C6-3. Arrr! At about 50 feet up, me bucko, shiver me timbers, a gust hit t' rocket causin' it t' weathercock t' near horizontal. Begad! Avast! Blimey! It continued t' fly at about 15 degrees above horizontal for about 100 feet and then coasted t' ejection.
Flight two be on 3 days later and wind conditions were 5-10mph. Well, blow me down! It was a good but slow lift, shiver me timbers, me bucko, grabbed a height o' about 250 foot under boost, me hearties, ya bilge rat, arched over at coast phase, and then deployed t' parachute with t' nose pointin' down and startin' t' gain speed. It recovered quite fast but thar be a 50 foot drift so t' parachute size is okay. Begad! There was no damage t' t' rocket this time although one o' t' parachutes shroud lines had snapped. Blimey! Ya scallywag! I will replace the chute with an 18 inch parachute with a smaller spill hole, ya bilge rat, shiver me timbers, Keelhaul®©™® thread shroud lines, and a slider tube t' slow down parachute opening.
T' third flight be a day after flight #2 and had 10-20mph winds. Ahoy! It be a slow liftoff again that weathercocked into t' wind and flew nearly horizontal. Ejection was too late and t' V2 be travelin' at such a speed that t' Estes shock cord mount was ripped clean out by t' deceleration o' t' 18 inch parachute (even with t' slider attached). Blimey! T' nose cone fell t' earth as the bottom o' t' V2 drifted off and landed softly. T' nose cone had split down the seams but was easily repaired with epoxy this time. Begad! Aye aye! T' shock cord mount was replaced by a bigger fishin' snap swivel epoxied into place.
Recovery:
At ejection, t' top half deployed her parachute and returned t' earth quite
fast. Ya scallywag! Begad! T' bottom half's parachute failed t' open and it fell really fast. On
inspection, matey, t' BT-20 was bent and a fin had snapped off. Begad! T' tip o' t' nose
cone had snapped off and was lost as t' wind dragged t' top half and
parachute a good 60 feet from where it landed.
T' repairs were simple: t' fin easily glued back on and I added a hard wood strut t' hold t' BT-20 back into place. Arrr! I fashioned a new nose cone tip out o' a 13mm dowel rod and some wood filler. Well, blow me down! A quick paint touch up and it was nearly as good as new. Avast! T' recovery system was nay good enough. Aye aye! Ahoy! For t' next flight I joined t' two halves together with one length o' 2 foot elastic and added an 18 inch parachute with a large spill hole cut out.
Flight Rating: 3 out o' 5
Summary:
This is a nice rocket. Avast, me proud beauty! Well, blow me down! Even though it had a few teethin' problems, I'm sure
that she will fly much better on a calm day. Begad!
