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

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