I am very happy with my TOPCAT. Built it in three weeks of evenings after dinner, spent about three hours a night on it . It does go together easy, I did not have a problem with the instruction manual, in fact I put it toghether useing the pictures more than written info. I made up some plywood canopy edge holders and used them where the canopy rim mates with the fuse to keep the gap even, worked great. The kit comes with a 1/4 x 20 nylon bolt to attach the rear of the canopy, this seems like a simple low tec way, but I put in a latch. I have flown it now at least 50 times, 15 from our grass field. I have a P-80 which I got from them also along with everything else they had avaliable, I bought it in one big combo pack. The kit and most of the items were shipped right away, the ones that were on back order took about a week to get. The one thing I did like about working witht TGA is that they kept me current on what was up with my order and when stuff was going to be sent out. I realize sometimes the manufacturer does not have a say if their suppliers are always on time, but keeping me informed is the next best time. The bottom line is they kept their word.
