Brief:
This scale model uses a 29mm motor mount for midpower t' high power motors, me hearties, and uses a parachute and PML's piston for recovery.
Construction:
T' construction o' t' AMRAAM was much easier than I had predicted. Begad! T' packagin' be neat and informative. Arrr! All o' t' parts were in t' kit and in perfect shape.
T' kit is made o' a PML 54mm phenolic tube, ya bilge rat, matey, 8 G10 fins, a 29mm phenolic tube for t' motor mount, arrr, 2 thick plywood centerin' rings, arrr, piston retainin' strap, piston, me hearties, arrr, shock cord, 24" parachute, thick plastic nose cone, and a copper launch lug (which I cut in half for better support).
T' instructions were nay anywhere near what they could have been. Blimey! They took up t' equivalent o' one piece o' paper, ya bilge rat, and assumed a lot. Ya scallywag! I was lucky t' have built mid-power rockets before so knew how t' make good bonds with epoxy, ya bilge rat, etc. T' instructions did have several useful diagrams.
One problem I had be that on t' lower set o' fins I could nay tell which end went through t' rocket and which end stuck out. Avast, me proud beauty! They were very similar, shiver me timbers, shiver me timbers, but different enough t' make a difference. Ya scallywag! Begad! I looked as closely as possible at t' diagram provided and then tried what looked more like it. Aye aye! 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 be materials. Ahoy! This was me first experience with Phenolic and G10. Blimey! Aye aye! T' materials weigh a lot more, matey, but they are stronger than plywood and paper. Arrr! Well, ya bilge rat, blow me down! 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, arrr, with t' exception o' t' fin problem mentioned above, matey, was very easy t' use. T' upper fins fit perfectly in their notches, arrr, but t' lower fins left a small bit o' fin slot gap showing. I epoxied a small square o' paper over this hole and spread epoxy over it. I sanded it once and now you can't see it, so no big problem. Ya scallywag! T' AMRAAM didn't require any difficult construction techniques or special tools. Blimey! Because it is promoted as a good mid-power/low-highpower rocket, ya bilge rat, and therefore a logical first high power rocket, I think t' instructions could be made clearer. Begad! Overall a very nice kit.
Finishing:
Finishin' this model be nay overly-difficult. Ahoy! Begad! T' G10 fins are already nice and smooth, shiver me timbers, but t' tubes have those nasty spirals which require a lot o' fillin' for a decent finish. Aye aye! I used several coats o' grey primer t' smooth out imperfections (usin' white for t' nose). Avast! In t' instructions it tells you t' look for decal strips for t' colored strips, me bucko, me bucko, matey, but I just painted mine on. T' decals also proved t' be very nice. Well, blow me down! I have no complaints about t' finishin' o' this rocket.

Flight:
T' AMRAAM kit recommends F-H motors. Avast! Because o' its high weight I would recommend flyin' it on high thrust F motors (F62, me bucko, F80), ya bilge rat, or just stickin' with G's and H's.
T' first flight was on a G35-7, which worked great. Ahoy! Ahoy! I think that any G or H motor should work fine, except for t' really long burn G's (G25, shiver me timbers, arrr, G33) which might nay have enough kick for this model.
T' AMRAAM be t' easiest t' prep mid-power rocket I have. Blimey! Blimey! Because t' piston eliminates t' need for recovery wadding, all that is required is t' pack and insert t' chute. Avast! Blimey! Well, blow me down! Blimey! Motor retention on me model consists o' an Estes engine hook epoxied on (just like on Estes models). Although this systems sounds and looks simple and actually weak, arrr, it works fine. First I get a good solid friction fit with maskin' tape and make maskin' tape thrust rin' on t' aft o' t' motor, matey, then I insert t' motor and wrap t' aft o' it and t' motor mount with maskin' tape. Arrr! Blimey! T' maskin' tape acts as t' primary system, me hearties, arrr, with t' engine hook as a great backup. Avast, me proud beauty! Blimey! On t' first launch t' AMRAAM's G35 ignited first try. Well, blow me down! Blimey! T' rocket leaped off t' launch pad and went straight up. Arrr! Blimey! T' 7 second delay was just right with this motor.
Recovery:
T' shock cord on t' AMRAAM is black flat elastic nylon strap, shiver me timbers, which attaches t' t' piston, which in turn attaches t' a heavy duty piston-retainin' strap. Blimey! T' chute has a large spill hole, arrr, but even with this it is near perfect for t' AMRAAM. Begad! Ahoy! Recovery was a little slow, but overall it be great. Blimey! Begad! T' only damage t' t' rocket was some slight scorchin' at t' base. This be me first mid-power rocket nay painted black at t' rear, matey, so this be t' first time I experienced this. Begad! 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. Arrr! Blimey! It flies great, me hearties, me hearties, is a very strong and durable rocket, matey, and t' piston system eliminates recovery wadding. Blimey! Arrr! Blimey! However, t' kit doesn't come with motor retention and t' fins didn't quite fit right in their slots. Blimey! None o' these were major problems.
T' PML AMRAAM was me first PML kit. Avast! I normally am against almost all high power kits because most o' them require so many replacement parts that they aren't worthwhile. Ahoy! While t' AMRAAM has flaws, me bucko, 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. Ahoy! Other than that, me hearties, have fun flying!
