I fly a version 2.0 unit and it's pretty nice. Survived a rocket malfunction where the apogee charge blew out the side of a very old thin walled rocket and it did a death dive from 3400'. Rocket didn't separate in two. The Aim 2 dutifully blew the main and a really cool zipper occurred, the sustainer shockcord broke then and the lonely little ebay came back by itself with the AIM 2.0 under a 6' parachute. Gentlest landing that ebay will ever have. The AIM 2.0 is fine.
Rocket was pushing 10 years old and was a single deploy originally and had a zipper. I then turned into dual deploy. I used a 34" long 38mm motor tube with 5 centering rings and the fincan is salvageable. Am going to reincarnate it again as a dual deploy again. I keep swearing I'm going to give up on 4" diameter thin-walled cardboard rockets but it's fun actually because everything has to work correctly. Period.
I know the failure sequence because I had a downward facing 720P camera recording everything. Kurt Savegnago
