Pml Amraam 2 !!

Well I know what is gonna happen here......"finish something" BLAH, BLAH, BLAH I placed an Order through Commonwealth for a PML AMRAAM 2 and a 29mm 40-120 hobby case. I AM planning on upgrading the MMT to 38mm and fly with an adapter untill I get my 38mm case I will be placing an order later on this week or mid next week through Hobbylinc for some Reloads and 38mm MMT tubing. I have also placed an order through Railbuttons.com for 4 series 1000 Delrin black rail buttons (2 for this 2 for another rocket) I would LIKE to make this adaptable for an altimiter bay when I fl it on I's (CCCOOOMMMMEEEEE OOOONNNN JRL1 !!) I am open for suggestion and tips on this kit and what everyone thinks of it I would also like suggestions on how to line my fins up?? I don't have a "mechanizm" or "device" (yet ) to align them I do have a triange I can use.

thanx, Ben

YES The AMRAAM2 is a great kit and is one of my favorite rockets. It flys great on a G64-7 but H128 was just made for this rocket

What's not to like? PML are quality kits and the AMRAAM is a cool looking rocket.

The only problem I see with your 38mm conversion is it will make it heavier and at some point your motor choice will be cut off due to the fact that your body tube is not recommended for Mach speeds. Quantum tube is great for finishing but not for speed.

You can make a jig from corragated cardboard. Cut a hole to fit your body tube snug. Mark the fin slots on the cardboard. Remove the cardboard and cut nice straight, slots for the fins. Assemble dry to check. When the jig is perfect, your fins will be perfect. Cut out a little cardboad from where the fin slots meet the body tube to avoid gluing the jig to the rocket. Use the same jig for the upper fins.

Hope this helps

I've been planning a 38mm AMRAAM 2, but considering that I've built my 1st and last QT rocket I'm going to do phelonic. Should be protty cool with a big I motor, sure hope you have big field.

well! It has ARRIVED!!
It came nicely packed form Commonwealth with my 29 40-120 case! cudos to Commonwealth placed it Monday night and I didn't expect to see it till Friday of Saturday! I have ditched the idea of a 38mm MMT I will stick with the 29mm. I was also suprised that the lower finslots stop about 1/4" before the bottom of the BT . I have decided to cut it so the slots are the bottom of the BT and I will make it like a fincan. I will be postimg many detailed pics I am also expecting some rail buttons tomorrow or Saturday, I will put the brass LL on AND the buttons so I have more opportunities.

thanx, Ben

here is another

looks good keep up the pics.

thanx, Ben

here is a closeup of the case. I hope to have a reload order placed by the end of next week I am thinking a BJ for the first flight

thanx, Ben

If you stick with the pistons, remember to check that they are freely moving immediately before you fly. The fit is temperature dependant.

I don't have this kit, but I've always liked the Amraam. I see from the poll that one person doesn't like it and 2 think it's ok. I wish these people would have explained why?

Ben, keep the photos coming

I have decided to cut off the bottom and make a fincan so it is a little stronger. here is the bottom of the BT marked with masking tape before the cut is made.

thanx, Ben

here is a photo after the cut.

here is a photo of the CR's glued on the MMT tube.


thanx, Ben

looks good, im also building a pml kit right now. looks like yours has those weird 4 ply plywood rings like mine did. i dont like them that much , they were hard to drill through nicely when i put in motor retention.

Love PML kits. Hate the AMRAAM...just think the fins are UG-LY!

So's ya know... we won't be able to drag race* if you put in a 38mm motor mount... just build it stock, other than the cut that you've already made... Also, it'll be easier to foam if you do 29mm... foaming with such a small space is a pain... Drill some holes in the fin tabs to allow the foam to get a better grip. Use 3/16" or 1/8" holes.

And about thsat cut... I would personally have simply lengthened the slots, as now it will no longer be a scale model (it'll be sport scale... but not scale). You need to lengthen the slot at the top so that the bottom CR can fit in there.

I llike everything about the PML kits... they're well worth your money.

*I'm planning on getting a Talon 2, and we'll be able to drag race them due to similar sizes and weights. But only if Ben doesn't radically modify it!!!

Well, the kit is already sport scale, it's nowhere near scale. Relative to the real one, the front fins are too far back and too small, and the rear fins are oversized on the PML amraams (for stability).

I didn't get a chance to finish posting pics I would of answered Jake's question and I don't know if I have said this before but I will say it again, I am NOT modifying it except for making it the fincan way! I will keep the 29mm MMT. BTW I went to the Hobby Store to look at the reloads (reload actually ) and I got the last 29mm they had, F40-7W if the wind isn't to bad this will be the first flight. Well back to the pics , this is of the cut I made in the fin. The fin is the big white thing in the upper right-hand corner (I know its totally white but the G10 reflected since its soooo smooth and I used to much flash I think ) i didn't plan it this way but you can see the other fins cut in the back-ground. I am ready to do some more assembling but my parents want me too finish some other rocket projects(or atleast advance on them) before I get to far in this one. SO I might not have any pics for a few days.

thanx, Ben

here is a photo of the 2 upper fins glued on they are in fact straight and are lined up with the lower (I think ) The white part is where I had to cut out my address of the box my dad said "I don't want my address on the internet "

thanx, Ben

I see what you're doing with the fins... didn't think about that

well I managed to squeeze in a little more work.... Here is a picture of the 3 forward fins glued on

thanx, Ben

here is a photo of the first lower fin being glued in place. the MMT is not glued in I am putting it in there to align the fins so they are all straight. To make shure they don't get permanently glued in I pull the MMT assembly out 10-15min after setting, before its to hard to pull out.

thanx, Ben

this one that shows the completion of the rocket so far


thanx, Ben

well my mom came home and found out I was wokring on it so I might be down and out fo rthe count for a day or 2 or more
well here is a pic of the fin on the MMT.

thanx, Ben

here is the last and final pic. It is of 2 fins on the MMT inside the body.

Uh oh. You've put your motor mount in upside down.
