As my title says, I am thinking about getting myself an Amraam 2. What do you guys think about this kit?
I left the piston in mine and have not had any issues. After a flight, I pull out the piston and wipe it down and I wash out the tube and dry it. During construction of the rocket, I put the tube in the freezer and sanded the piston enough that it would easily slide up and down the tube when pulled out of the freezer. I did not want the piston sticking in cold weather. I do have a 3" PML AMRAAM that I did remove the piston. I just cut it right below the piston and then tied additional lengths of tubular nylon to the strap. Never had any issues that way either.

I pulled the trigger on it:

Just my opinion, but you should have ordered the 38mm option on the IO.
Leave the lugs on and put buttons on another sideI got the 2" one for free already built from my club president. He acquired a lot of built stuff from rocketeers retiring/passed so he let people pick what they wanted. I'll mainly fly mine on probably an F67 or another F motor since we have a lot of trees around here. I love it though. It's phenolic not quantum and probably 15-20 years old I'm guessing. It has brass 1/4" lugs on it which I would like to rip off and do rail buttons instead.
Leave the lugs on and put buttons on another side
Never would have guessed that. What motor?And effectively double the drag on the rocket? I ran a sim on a 2” rocket without rail buttons and then with rail buttons and I was surprised when the difference in altitudes was nearly 800’.
Never would have guessed that. What motor?
I have a hard time believing the sim and that with and without rail buttons that there would be an 800' difference in altitude. I routinely fly mine with G54 motors which gives and altitude around 800 feet (visual estimate). It has both lugs and buttons. Hard to believe that if I removed them I would get 1600'. May be I misunderstood your comment.
Understood. And yes I have rocksim and also use openrocket. I was just commenting on my real world experience and suggesting that the sim doesn't seem to reflect what I would expect when you actually fly the rocket.
Whoever built the one I have didn't leave any motor tube for a normal retainer, I think it was designed for a triangle shaped screw on plate which I didn't have so I had to get a new flat bottom retainer which I kind of prefer more, though I was misled by Apogee on it actually being for flat bottomed rockets. I'll try and get a picture of it.
