Brief:
My first attempt at a plastic model conversion (PMC). Avast, me proud beauty! Begad! 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, detailed instructions and decals
(except me kit didn't contain t' decals). Well, blow me down! Since I wanted t' fly this kit and
not have it sit on a shelf, I be nay too worried about t' missin' decals.
T' kit itself is for a V2 rocket sittin' on a launch pad. Aye aye! Blimey! 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. Ahoy! Ahoy! 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. Arrr! Ya scallywag! T' A5 plug has t' be cut down t' accept a BT-50. Blimey! Usin' t' rotary
tool, me hearties, me hearties, this was easy t' do as t' rough edges were smoothed down usin' a
grindin' disk. 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. Well, blow me down! Avast! [Note: T' fins have an attachment rod on t' lower part. Avast, me proud beauty! This is t' attach t' V2 t' t' base stand. Well, blow me down! I removed these with t' grinder.]Glue t' middle and upper body tubes together. Avast! 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. Begad! However, arrr, me bucko, I did nay want an ejection charge goin' off inside the V2 for a number o' reasons:
To get around this, shiver me timbers, 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. 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. Blimey! This be cut using
a cuttin' disk and cleaned up. I then slid t' plug into one end o' t' BT-20
and applied epoxy t' t' end o' t' plug. Ya scallywag! Begad! Next, 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. Begad! [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. Well, blow me down! Ya scallywag! 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, 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, leave this off for now as t' model may need weightin' at t' top t' raise t' CG. Well, blow me down! Blimey! Avast! Blimey! I decided to have t' rocket recover in two halves. Avast, me proud beauty! Blimey! Begad! Blimey! 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). Begad! 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. Begad! 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. Avast! Well, blow me down! Blimey! This spoiled the look a bit and I suppose that I could have used an internal lug, shiver me timbers, but that would have taken a lot o' time. Arrr! Blimey!
Finishing:
I went for a camouflage pattern instead o' t' black and white scheme. I used
spray can paint and went for an original design that I rushed. Ya scallywag! Ya scallywag! It was nay the
best finish that I've done. Begad! This is me first PMC I didn't want t' spend hours
finishin' t' rocket t' see it possibly destroy itself first flight. Also, shiver me timbers, I
sprayed t' body tube fluorescent green so I could see it in t' grass because
camouflaged rockets are hard t' find! As I mentioned above, ya bilge rat, thar should have
been decals with t' kit but me box did nay have any.
Construction Rating: 5 out o' 5
Flight:
Before preppin' for flight, arrr, 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. Aye aye! At over six ounces, this rocket should
be flown on a D motor, ya bilge rat, however, me hearties, an 18mm motor be t' biggest I can use. Well, blow me down! A C6-3
should lift it.
For t' first flight on March 13, 2006, 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. Avast! Avast! Normally I would nay fly in these conditions, matey, matey, matey, but I be eager t' see me new project in t' air. Aye aye! A standard Estes 3mm rod was used. Well, blow me down! Begad! T' V2 lifted slowly off t' pad, arrr, on a C6-3. Begad! Well, shiver me timbers, blow me down! At about 50 feet up, a gust hit t' rocket causin' it t' weathercock t' near horizontal. Well, blow me down! It continued t' fly at about 15 degrees above horizontal for about 100 feet and then coasted t' ejection.
Flight two was on 3 days later and wind conditions were 5-10mph. Begad! It was a good but slow lift, arrr, grabbed a height o' about 250 foot under boost, ya bilge rat, arched over at coast phase, and then deployed t' parachute with t' nose pointin' down and startin' t' gain speed. Well, blow me down! It recovered quite fast but thar was a 50 foot drift so t' parachute size is okay. Ahoy! There was no damage t' t' rocket this time although one o' t' parachutes shroud lines had snapped. Begad! I will replace the chute with an 18 inch parachute with a smaller spill hole, 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. Well, blow me down! It was a slow liftoff again that weathercocked into t' wind and flew nearly horizontal. Ejection was too late and t' V2 was 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). Ahoy! T' nose cone fell t' earth as the bottom o' t' V2 drifted off and landed softly. Arrr! Blimey! T' nose cone had split down the seams but was easily repaired with epoxy this time. T' shock cord mount was replaced by a bigger fishin' snap swivel epoxied into place.
Recovery:
At ejection, me hearties, t' top half deployed her parachute and returned t' earth quite
fast. Aye aye! T' bottom half's parachute failed t' open and it fell really fast. Avast! On
inspection, me bucko, t' BT-20 be bent and a fin had snapped off. Aye aye! T' tip o' t' nose
cone had snapped off and be 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. Aye aye! Avast, me bucko, me proud beauty! I fashioned a new nose cone tip out o' a 13mm dowel rod and some wood filler. Begad! A quick paint touch up and it was nearly as good as new. Avast, me proud beauty! T' recovery system was nay good enough. Avast, me proud beauty! Ya scallywag! 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 bucko, me proud beauty! Blimey! Even though it had a few teethin' problems, I'm sure
that she will fly much better on a calm day. Avast! Avast! Blimey!
