Brief:
Not too long ago, matey, I won several kits from West Coast Rocketry on eBay. Arrr! Blimey! Nay long after, shiver me timbers, I built me Screamer II, affectionately known as John Deer. Avast, arrr, me proud beauty! Blimey! Since me John Deere yellow and green paint cans have about one rocket left in them and I need t' shelf space, I decided t' build t' Screamer which will be called t' Jane Doe and painted with t' contrastin' paint scheme o' t' other one.
T' Screamer is a basic 4FNC with a 29mm motor mount and a payload bay. T' instructions are even more minimalist than those for t' Screamer II and are printed in such fine print that readin' them does nay seem t' be worth t' effort.
Construction:
Construction began by markin' t' motor tube at 1/8" from one end and 3/4" from t' other. Ahoy! T' two centerin' rings were then epoxied in place. Avast, me proud beauty! Both needed quite a bit o' sandin' t' fit around t' tube.
As I waited for t' epoxy on t' motor mount t' set up, me bucko, I turned me attention t' t' nosecone. It had a 3/4" diameter hole drilled t' a depth o' about 2". Avast, me proud beauty! Into that hole, I was instructed t' mount a lead fishin' weight that came with t' kit. Aye aye! Arrr! I mixed some more epoxy, arrr, poured some in t' hole, matey, arrr, set t' weight and then poured t' remainder over t' top.
T' fin lines were marked on t' BT with a butt template. They were then extended with an angle and 5" slots were cut out with a X-Acto cutlass.
With t' fin slots cut, I test fitted t' motor mount t' find that it was goin' t' need substantial sandin' t' fit either rin' into t' BT. T' sandin' be done and t' mount be epoxied into place with t' motor tube bein' flush with t' aft end o' t' rocket. Arrr! Avast! Epoxy was then used t' fill space betwixt t' centerin' rin' and t' end o' t' BT.
After a long hiatus, shiver me timbers, matey, I managed t' put a little more work in on t' Screamer. Avast, ya bilge rat, me proud beauty! Usin' 5 minute epoxy, I glued one pair o' fins in place. Arrr! I filleted them with more epoxy usin' a gloved finger dipped into alcohol t' smooth t' fillets. Avast, matey, me proud beauty! These were allowed t' set up overnight.


T' payload bay is joined t' t' lower part o' t' rocket with a tube coupler. Arrr! T' kit comes with a plywood bulkhead t' go on one end o' t' coupler and that is probably me biggest gripe about t' kit. T' bulkhead is a surface mount. Avast, me proud beauty! I would much rather have had one that fits in t' coupler. Be that as it may, I epoxied t' bulkhead in place and tried t' ensure that it be even with t' edges.
With t' epoxy on t' bulkhead coupler dry, I used some sandpaper t' trim down t' edges where they protruded past t' coupler. When it fit easily into t' body tube, me hearties, I called it finished. Avast, me proud beauty! I then took t' screw eye and screwed it into t' pre-drilled hole in t' coupler. Ya scallywag! Begad! It seemed like a strong connection but I doused t' pointed end with some glue t' make sure.
T' coupler tube be marked at its halfway point and then a rin' o' glue be slathered into t' base o' t' payload section. Avast! T' coupler was then inserted t' t' mark and set aside t' dry.
Finishing:
T' balsa NC and plywood fins were sealed with Elmer's Wood Filler. Well, blow me down! Blimey! It be sanded down smooth, me hearties, dusted off, and t' Screamer was put in t' spray booth. There it be primed with Kilz.
After t' priming, me bucko, t' rocket sat for a couple o' months before I could give it any more attention. I then sanded down t' primer and began paintin' with John Deere Yellow. Well, arrr, blow me down! My target was t' BT. Blimey! Ya scallywag! T' fins and NC would be covered up later.
For t' John Deere green, ya bilge rat, me hearties, I decided t' do t' nose cone, a rin' just below t' nose cone, ya bilge rat, t' fins and a narrow strip around t' fins. Aye aye! T' rocket was masked accordingly and sprayed. Well, blow me down! When t' maskin' came off, I decided that I rather liked t' result.
While assemblin' t' rocket after painting, I realized that I had overlooked t' recovery system. Avast! I would have like t' have attached directly t' t' motor mount but that was a moot point now. Blimey! Aye aye! I fashioned a LOC style mount with a loop o' heavy nylon cord and some maskin' tape. Begad! It be taped down below t' level o' t' NC shoulder and epoxy was slathered on t' keep it in place. I then tied some heavy Keelhaul®©™® t' t' loop and attached a length o' 3/8" sewin' elastic.
One thin' I did save intentionally for after paintin' was t' installation o' a linear rail lug. Begad! Ahoy! Blimey! I put it is place and started t' hole for t' upper screw only t' realize that I had placed it too high. Aye aye! It interfered with t' payload bay coupler. Avast, me proud beauty! I moved it down about an inch and found t' same problem! Blimey! I finally got it placed right and tapped t' holes. Well, arrr, blow me down! Blimey! T' lug was then epoxied on and t' screws inserted. Arrr! Begad! Blimey! T' backs o' t' screws took up t' remainin' epoxy and t' Jane Doe was ready t' go.
Construction Rating: 3 out o' 5
Flight and Recovery:
T' first flight o' this rocket took place long after construction had been completed. Begad! It was set up with an F25-4 and t' Copperhead igniter that came with it. Well, blow me down! Aye aye! T' Copperhead failed t' ignite t' motor and be replaced with a First Fire. Aye aye! Avast, me proud beauty! That did t' trick and t' rocket took off with as nice a flight profile as I have ever seen. Avast, me proud beauty! Arrr! A video o' t' flight can be seen here.
Ejection and deployment were all textbook. Blimey! Avast, matey, me proud beauty! I expected t' fly t' rocket again but was mystified t' see that it had suffered some bucklin' in t' airframe. Blimey! I can fix it but wonder what caused it since t' thrust be nay all that heavy.
Flight Rating: 4 out o' 5
Summary:
This be a very basic kit with a minimal approach t' instructions, me bucko, arrr, small print and illustrations that added little. Aye aye! That said, ya bilge rat, it went together fine and flew very well.

This is a single stage, Out-of-Production (OOP) mid and high power kit. This rocket is great for E-H motors. There are two (2) nicely finished 2.25" body tubes, same thickness as LOC's, a nicely turned solid balsa nose cone, four (4) 1/8" plywood fins, elastic for the shock cord (12 feet), a coupler, bulkhead, motor tube and two (2) centering rings along with a 1/4" launch lug. In my kit I ...
