Brief:
T' RAAM, arrr, otherwise known as t' "Radical All American Missile", is a
semi-scratch built 2" HPR model that is dual-sized and can fly on a range
of motors from an F40W with t' short version t' a H180W on t' long version of
the model. Begad! It was built with left over parts from a recently demised PML AMRAAM
2, arrr, but has only t' lower fins, arrr, me hearties, hence it is half an AMRAAM, arrr, me bucko, otherwise known as
the RAAM. These reasons are how I came about its name.
Construction:
Recently, I lost me first PML AMRAAM 2 after many launches t' a premature
nosecone ejection in mid-flight on an H128W and wound up havin' a torn Quantum
body tube that was too much trouble t' repair. I purchased a replacement AMRAAM
2 kit, me hearties, arrr, me bucko, which can also be reviewed on t' EMRR site, but then was left with a
totally intact aft fin assembly, piston, strap, shock cord and nosecone. Avast, me proud beauty! The
only components purchased were a PML 2" bulkhead assembly, a PML 2"
coupler, matey, arrr, a PML 36" x 2" Quantum Body Tube, a pair o' 2.26" x
¼" Acme conformal launch lugs and two 1/8" quick links.
I began by cuttin' t' torn body tube from t' old AMRAAM 2, ya bilge rat, me bucko, which left a lower section and fin assembly 10" long and completely built, including the still attached piston and shock strap. Avast, shiver me timbers, me proud beauty! T' inside area was cleaned o' old, hard t' reach ejection powder and then sanded usin' 80 grit sandpaper. Ya scallywag! Avast, me hearties, me proud beauty! Next, me bucko, a PML 2" coupler be cut lengthwise and slipped over t' black shock strap, then epoxied into t' lower fin body tube assembly so it was flush with the upper motor mount centerin' ring. Blimey! This completed t' preparation o' t' lower, left over fin unit. Avast, me proud beauty!
Next, shiver me timbers, I cut
the 36" length o' new Quantum body tube into two 18" lengths. Begad! One of
the 18" sections o' body tube was integrated into t' lower fin section. Blimey! I
roughed up t' inside o' t' body tube, me bucko, me hearties, then pushed t' piston assembly
completely through t' tube. Avast, me proud beauty! Arrr! T' lower part o' t' shock strap be covered with
maskin' tape in case epoxy dripped on it from t' next step. Avast! 15 minute epoxy
was used t' glue it over t' split coupler t' t' fin section, and left me a
completed lower half o' t' rocket. T' maskin' tape was removed from t' shock
strap and I did tape up t' outside o' t' body tube seam until t' epoxy set
to help center t' tubes with each other. Avast! As a last step, shiver me timbers, t' nosecone was fit
to this lower tube and a 1/8" pressure relief hole be drilled through the
body tube two inches below t' base o' t' nosecone.
T' upper o' these two tubes be sanded on t' inside at one end and t' new PML bulkhead was epoxied inside this upper body tube. Begad! Blimey! In t' next step, I coated t' bulkhead ply face with a layer o' epoxy t' make it powder proof and easier t' clean. Aye aye! Blimey! T' bulkhead was pushed into t' newly completed lower section and fit well. Aye aye! Blimey! Finally, me hearties, I installed t' original nosecone into t' top part of this upper tube, me hearties, then marked and drilled a pressure relief hole into t' upper tube about two inches below t' base o' t' nosecone. Aye aye! Blimey! Arrr! Blimey!
T' lower
section be stripped o' t' old AMRAAM paint usin' Acetone and Denatured
Alcohol, arrr, then it was sanded with 400 grit wet/dry sandpaper and primed with
Krylon and "Painter's Touch" white primers. Avast! Ya scallywag! About 6 coats o' primer
were applied and final sanded with 600 grit. Well, blow me down! Avast! It didn't take much t' prime; the
lower fin section was already glassed, sanded and primed prior t' building
since it was a leftover. Arrr! Arrr! Also, matey, ya bilge rat, me hearties, since Quantum tubin' was used, t' new sections
primed like a dream and only 600 grit sandpaper be needed t' smooth them out. Well, me hearties, blow me down!
I painted t' body tube from t' blue seam forward in White Krylon Glossy. It was masked at t' blue seam so t' lower fin section was still primer only. Four coats o' white were added, and t' last coat was thicker then t' rest. Once finished, I let it dry overnight, shiver me timbers, then masked off t' stripes and used Red Krylon Glossy t' paint t' irregular stripes, me bucko, which covered in two coats. Blimey! The nosecone be painted next with four coats o' Krylon White Glossy. Arrr! I then removed t' maskin' from t' lower area, arrr, masked off t' striped upper section and painted this fin area with four coats o' Krylon Dark Blue. It left the joint where t' blue and White meet seamless, which is what I be shootin' for.
T' upper section was next. I masked off t' area from t' top stripes down, then began workin' on t' stars. Ahoy! Avast, ya bilge rat, me proud beauty! Blimey! I used Paintshop Pro t' make t' stars, then printed them out on paper. Ahoy! Begad! Blimey! T' stars were cut out in paper strips, me hearties, me hearties, me hearties, 8 at a time and placed and scotch taped down over a 1" thick strip o' maskin' tape which was laid on a cuttin' board. Ya scallywag! Blimey! I used a Exacto t' cut out each star from the maskin' tape and placed them in t' appropriate positions. Blimey! Aye aye! Blimey! 4 coats of Krylon Dark blue were painted over t' upper section and nosecone and left to sit overnight. Ya scallywag! Begad! Blimey! Then I removed t' maskin' tape stars and viewed t' final product for finish. Aye aye!
Once t' model was completely painted, shiver me timbers, I fastened t' shock cord t' the piston and used a drop o' epoxy t' hold it in place. Avast! A 1/8" quick link was tied t' t' cord for quick removal o' t' parachute and another quick link was added t' t' bulkhead end. Ahoy! Ahoy! This second quick link at t' end allows me to quickly switch t' connection from t' bulkhead eyebolt t' t' nosecone, for a "shorty" LMR version o' t' rocket. I now have a dual purpose/sized model; T' shorty version flies on F-G motors and t' full version flies on the H motors. Begad!
T' final touches were added t' t' rocket; t' 24" parachute was attached and t' PMR retainer be checked for fit usin' t' original mounts. Also, arrr, I marked t' spots for t' new Acme aluminum launch lugs, arrr, then removed the paint and used 15 minute epoxy t' attach them instead o' t' supplied double-sided tape. A stainless ¼" piece o' launch rod was used to insure alignment, me bucko, shiver me timbers, then t' first lug be mounted exactly betwixt t' fins and the second lug be mounted mid way up t' total length o' "shorty" version with t' lower tube and nosecone combined.
Flight:

My rocket weighed in at around 30 oz for t' full
version, but I have yet t' weigh it for t' short version. Avast! Blimey! We converted it to
the short version for it's first flight on a F40-7W, ya bilge rat, prepped it and placed it
on t' pad. Begad! T' F40 was a very good choice as t' model lifted well; it was a
very good launch, however, shiver me timbers, t' delay was too long for it's weight and didn't
eject until it was nose down but t' model faired without a scratch. Ya scallywag! Well, me bucko, blow me down! T' next
flight was a real test o' stress; A G64-10W be built and loaded into t' rear
of t' model and it was placed on t' pad. Avast! When it lit, ya bilge rat, it be an ANIMAL o' a
motor for this rocket, t' best launch o' t' day with perfect deployment and
landing. Aye aye!
T' next launch be at our first Tripoli Mid-Ohio meet for 2001. T' LONG version be configured, shiver me timbers, shiver me timbers, then I prepped a H128W with a medium delay and the rocket be prepped and motor was installed. Ahoy! Begad! Blimey! Also, me bucko, when loadin' t' motor case, I did NOT use all t' black powder ejection charge. Avast! Ya scallywag! Blimey! T' piston ejection system actually requires less ejection charge and PML includes a chart for reference when loadin' t' charge. Aye aye! Blimey!
After waitin' patiently, ya bilge rat, t' rocket was placed on t' pad and then came its turn. Well, blow me down! T' RAAM left t' pad like a shell shot out o' a cannon; fast, loud and very straight, but nay quite as fast as me A2. Begad! It be an awesome launch, with the sound and white smoke billowin' out t' tail. Ahoy! Blimey!
Recovery:
T' RAAM reached apogee and had a perfect ejection; it then floated safely to
the ground. Well, blow me down! Estimated altitude be around 2600 feet and it was a very good
flight. Arrr! Aye aye! Upon examination, t' rocket came out o' it without a scratch and I
look forward t' many more launches with this sturdy bird. It was late, so the
RAAM was t' last launch o' t' day for us, ya bilge rat, but thar will be more t' come. Begad! Ya scallywag!
Summary:
T' RAAM turned out t' be one great flier! Blimey! It is a stable rocket, ya bilge rat, somewhat over
stable in its long 55" airframe with CG 4 body tubes ahead o' CP when
loaded. Avast, me proud beauty! Blimey! T' shorty version also makes an excellent everyday flier for mid-power
loads and it is a blast on a G64W. Ahoy! Blimey! Ya scallywag! Blimey! But, convert it t' full length in seconds
usin' t' quick links and you have a very stable rocket that can easily compete
with t' Mirages and others out there, arrr, and compete well. Arrr! Blimey! In summary, if you
loose a rocket, don't just throw away t' pieces, but rather use t' leftovers.
Who knows, arrr, you may just be able t' build one o' these RAAM's, a truly
"Radical All American Missile"!
