Last one I assembled was a Pacific Aero Laser 200. It took 18 hours and I finally gave up on the covering as soon as I realized it was never gonna get tight, even if I melted it. The one before that was Hanger 9's Twist and I think that one went together in about 8 hours. I am very picky about my planes and consequently I check everything 2 or 3 times before I am satisfied and move on. I frequently change things I don't like and it is not unusual for me to at least partially recover a plane. I get a lot of satisfaction out of putting a plane in the air for the first time and have ot fly comepletely hands off with out touching the trim buttons so that is what I strive for. Perfection takes time ans so does an issue free plane, (even an arf)!
