Amraam 4 PML

I would like to ask those of you who have built this already,
What was your final actual loaded weight without motor?
you know sanded painted,Packed Chute(s),electronics, batteries, everything except motor.
Mine came in at 8lb 4oz setup for dual deployment and boostervision camera.
I am just curious how heavy it is comparative to others.
Thanks, Brian

That is slightly heavier than mine. Mine came in a just under 8lbs unloaded and 8.5lbs loaded with an I435.

I didn't use the qwick-switch adapters, I added a 54mm Aeropack and was phenolic (not QT)

I didnt know the wieght of mine but the PML AMRAAM kit I had was the best flying bird I ever flew. If only I could have kept it away from the road upon landing!

Mine weighs 7 1/2lbs...it has flown on everything from a J180 to a J460 and has logged over 40 flights on J motors.

I been thinking about getting the 4" version in phenolic .

I have the small entry level PML Amraan and its an awesome rocket. Thing is virtually indestructable and flies great on any 29mm motor you can throw at it. My only regrets is that i should have put a 38mm motor mount in it.

I do love the AMRAAM 2! I crashed it and put a LOC BT on it. I really pushed it last year on Todd Harrisons H1000 motor! Hit like 2500' coolest flight on it ever!

I have a J1999 ready for my 4" PML ARMAAM. I figure it will either be a really cool long coast, or a whole lot of bits and pieces floating down. I'm nervous for my MAWD in it though.

Are the kits fiberglass? I assume so.

Standard PML phenolic with G12(or G10, I foget which) fins. No tip-to-tip FG, just good ol' TTW fins.

Gonna be cool either way. 800 pounds of thrust for 0.77 seconds.

You really need to know what you want to use in it when you get it.
The qt which is what mine is, cant go over mach and maybe something about altitude also. There is a motor kit u can use called kwik switch but even it has 2 versions to handle longer motors. I got the longer version which I suggest if you go with the kwik switch. I do like the thing myself 29mm up to 54mm motors and all you do is change the interchangable motor tubes. You have 54mm base and a 38mm+29mm adapter tubes. pics will follow.
You can order it with the phenolic tubing which can then be fiberglassed for really crazy stuff like heada talking about, or just mach speed. I believe here and now that if heada does not put glass on fins at least, it will shred:surprised:.
Now heada, prove me wrong and show us the J1999 pics!

Come on up and see it for yourself! Gonna fly it Sept29/30 at Muncie, IN (not that far from KY) I'm a bad photographer but there will be several people there who are MUCH better than I am. I'll see if anyone can capture it going up (something about it going over 100 mph at the end of the rod) I'll have to look at the sims again, but I think it only hits mach 1.2 or 1.4 or so. Nothing too bad.

I've flown it on everything from an H999 to a J415 and have yet to have any problems (that is, when I remember to arm the electronics)

PML makes great kits and I think the 4" AMRAAM is one of the better PML kits.

Amraam 4 with QT and foamed fin can and nose cone. DD with 2 altimeter and 2 batteries with beeline tracker. 8lb 4onces.

See the link on my website below. This Amraam 4 has seen about 9 flights and it's always reliable for a good one. Weight has been between 8 and 9 lbs loaded -- I build heavy!

Biggest motor so far is a Aerotech J540. I've considered going larger, but one of the constraints is the short motor tube...

Aaron,

I would most likely have problems with you flying that rocket at my field, using the motor you specified and especially with the stock fins. so many times I see people overstressing airframes with little regard about safety. They are usually turned away at our field and for good reason...Safety first! I would suggest you check with PML on the stress the stock model can handle before making such an attempt, then build accordingly and fly safe.

Yes I foamed my fins also with the store bought STUFF. I like that it only doubles vs others that have even more expansion. My first flight was an I315skid at our local Quarkers launch and was an okay flight. The motor seemed to take alot of time getting up to pressure and I think it really hurt the perfomance. It truly was nothing like the first I315skid I did in another model.

I agree safety is very important in our hobby but PML phenolic body tubes and G10 fiberglass fins can withstand the 52Gs that a flight on the J1999 would put out and then some. It would not break the waiver nor mach (just barely over 5000' with a 6000' waiver and 650mph)

Yes, it is an extreme flight but more extreme flights have been made using the same PML components before. I have launched this same rocket on an I154J, I357T, I435T, J350W, J415W, I540WT and most recently an H999N(I might have missed a few motors, I've had this rocket for several years). The H999N, while the burn time isn't quite the same, put the airframe under nearly the same stresses that the J1999N will put it under (47G on the H999N and 52G on the J1999N) and while not quite as fast, the rocket has gone close to the speed that it would see on the J1999N (500mph on the J415W, 650mph on the J1999N)

I understand that not every field has the same views on extreme flights but I would think that you, being a member of the L3CC, would have seen more than your fair share of extreme flights and would not deny a flight just because the motor has a high level of thrust.

Mine is 7 1/2 lbs and just loves J350's

My old PML Amraam 4 with QT flew great on AT K1100 and AMW K670 GG motors. It flew a little over 6k on these motors. Nice flights.

bowhunter , anybody, ever use the j570 with QT?
