Welcome back to model rocketry! I came back in 2010, and the diminutive Star Trooper was one of my first kits. It's still flying after some 20 or more flights, on 1/4 and 1/2 A motors. I've never tried a full A, since I really hate losing rockets.
I put an A10-3T in mine yesterday and it landed within 30 yards of the pad. I also replaced the stock streamer with a silver mylar one for better visibility.
