Rocket PicBrief:
This scale model uses a 29mm motor mount for midpower t' high power motors, and uses a parachute and PML's piston for recovery.

Construction:
T' construction o' t' AMRAAM was much easier than I had predicted. Ahoy! T' packagin' was neat and informative. Aye aye! All o' t' parts were in t' kit and in perfect shape.

T' kit is made o' a PML 54mm phenolic tube, matey, 8 G10 fins, a 29mm phenolic tube for t' motor mount, me bucko, matey, 2 thick plywood centerin' rings, ya bilge rat, arrr, piston retainin' strap, matey, piston, shiver me timbers, shock cord, 24" parachute, thick plastic nose cone, matey, and a copper launch lug (which I cut in half for better support).

T' instructions were nay anywhere near what they could have been. Aye aye! They took up t' equivalent o' one piece o' paper, me hearties, me bucko, and assumed a lot. Aye aye! I be lucky t' have built mid-power rockets before so knew how t' make good bonds with epoxy, arrr, matey, etc. Begad! T' instructions did have several useful diagrams.

One problem I had was that on t' lower set o' fins I could nay tell which end went through t' rocket and which end stuck out. They were very similar, me bucko, but different enough t' make a difference. I looked as closely as possible at t' diagram provided and then tried what looked more like it. I'm still nay sure if I did t' right one! But t' only time I think it looks odd is when it is held up t' me Estes AMRAAM (of which I have know nothin' o' scale accuracy).

One thin' I did like about t' construction was materials. Ahoy! This was me first experience with Phenolic and G10. Well, blow me down! T' materials weigh a lot more, but they are stronger than plywood and paper. Avast! Begad! T' copper launch lugs were also very nice. I used 60 minute epoxy throughout construction and ended up with a very strong-seemin' rocket.

T' AMRAAM, me hearties, shiver me timbers, with t' exception o' t' fin problem mentioned above, me hearties, was very easy t' use. Well, blow me down! Begad! T' upper fins fit perfectly in their notches, me hearties, me bucko, me hearties, but t' lower fins left a small bit o' fin slot gap showing. Arrr! I epoxied a small square o' paper over this hole and spread epoxy over it. Ahoy! Avast! I sanded it once and now you can't see it, me hearties, so no big problem. T' AMRAAM didn't require any difficult construction techniques or special tools. Avast! Avast! Because it is promoted as a good mid-power/low-highpower rocket, shiver me timbers, and therefore a logical first high power rocket, I think t' instructions could be made clearer. Blimey! Overall a very nice kit.

Primed

Finishing:
Finishin' this model was nay overly-difficult. Begad! T' G10 fins are already nice and smooth, but t' tubes have those nasty spirals which require a lot o' fillin' for a decent finish. Begad! I used several coats o' grey primer t' smooth out imperfections (usin' white for t' nose). In t' instructions it tells you t' look for decal strips for t' colored strips, shiver me timbers, but I just painted mine on. Ahoy! T' decals also proved t' be very nice. Arrr! I have no complaints about t' finishin' o' this rocket.

Construction Rating: 4 out o' 5

Flight:
T' AMRAAM kit recommends F-H motors. Begad! Because o' its high weight I would recommend flyin' it on high thrust F motors (F62, F80), or just stickin' with G's and H's.

T' first flight was on a G35-7, which worked great. Begad! I think that any G or H motor should work fine, except for t' really long burn G's (G25, G33) which might nay have enough kick for this model.

T' AMRAAM be t' easiest t' prep mid-power rocket I have. Because t' piston eliminates t' need for recovery wadding, all that is required is t' pack and insert t' chute. Arrr! Motor retention on me model consists o' an Estes engine hook epoxied on (just like on Estes models). Arrr! Although this systems sounds and looks simple and actually weak, ya bilge rat, matey, it works fine. Arrr! First I get a good solid friction fit with maskin' tape and make maskin' tape thrust rin' on t' aft o' t' motor, then I insert t' motor and wrap t' aft o' it and t' motor mount with maskin' tape. Well, blow me down! T' maskin' tape acts as t' primary system, me hearties, with t' engine hook as a great backup. On t' first launch t' AMRAAM's G35 ignited first try. T' rocket leaped off t' launch pad and went straight up. Blimey! T' 7 second delay was just right with this motor.

Recovery:
T' shock cord on t' AMRAAM is black flat elastic nylon strap, which attaches t' t' piston, which in turn attaches t' a heavy duty piston-retainin' strap. Begad! T' chute has a large spill hole, shiver me timbers, but even with this it is near perfect for t' AMRAAM. Avast! Recovery be a little slow, but overall it was great. Arrr! T' only damage t' t' rocket be some slight scorchin' at t' base. Begad! This be me first mid-power rocket nay painted black at t' rear, so this was t' first time I experienced this. Well, blow me down! It does give t' rocket a sort o' battle-worn look which I think is cool.

Flight Rating: 4 out o' 5

Summary:
T' AMRAAM overall is a great kit. It flies great, shiver me timbers, matey, is a very strong and durable rocket, shiver me timbers, and t' piston system eliminates recovery wadding. However, matey, t' kit doesn't come with motor retention and t' fins didn't quite fit right in their slots. None o' these were major problems.

T' PML AMRAAM was me first PML kit. Begad! I normally am against almost all high power kits because most o' them require so many replacement parts that they aren't worthwhile. Arrr! While t' AMRAAM has flaws, ya bilge rat, I still recommend it for those who don't enjoy designin' their own rockets.

My only advice for someone buildin' this kit is t' add positive motor retention and use a good quick-cure epoxy. Avast! Other than that, shiver me timbers, have fun flying!

I found the kit to be an excellent value and performer. The high quality of the materials supplied makes for a quick building and truly rugged model. The flights are straight and exciting and the rocket deploys very well. I found that neither the Quantum tubing nor the piston tubing are perfectly round. I tested the fit by sliding the assembled piston into the body tube while turning the piston until I found the smoothest operation. Then using a permanent marker, mark the body tube and piston assembly so you can always prep the rocket with the piston in that orientation. I also place some cellulose wadding between the motor and piston, as well as some talc. The body tube can be cleaned of ejection charge residue with a damp towel or wet wipe. I was initially skeptic of the 24" parachute with the spill hole. It seemed too small for a rocket of this size and weight, however, because of the strength of the components used my model has sustained no damage to date other than some paint scuffs. My favorite motor for the rocket is a G35-7 Econojet. Ejection is a fraction of a second after apogee. On the rockets first flight it landed in a drainage ditch filled with muck and frogs. Although completely submerged and filled with slime, I was able to hose it down and dry it off with out any damage. Try that with a cardboard tube!

Last October, I flew the Amraam 2 on a G motor and somehow the nose/chute and the body separated (my fault I am sure). I never found the nose/chute but I did find the body; stuck in a tree. It stayed there all winter and I was fortunate to recover it in May this year. I replaced the nose, three canard wings, one main wing, shockcord and chute. The Quantum tube developed a small crack near the motor mount and I glassed that over. The Amraam flew in July this year on an F motor ? the flight was perfect. I cannot think of any other kit that would withstand a Chicago winter and come back like this. This was my first PML kit. Now I have six others.

This was my third PML kit and HPR. Great kit. Had some 38mm tube laying around and couldn't help myself. Upgraded motor mount to 38mm, foamed area that was left in can and installed a slimline eng retainer and slimline 38/29 adapter. Very solid and stable flyer. Superb quality materials too.
