Usually you fly the heck out of the trainer then start learning stunts with your second plane and you get to the point of no panic attacks when you get a dead stick. Those poor second planes take a beating and get a lot of repair work. By the time you get to the third plane you have figured out the little things like keeping the nose down with a dead stick and how to do an S or two so you aren't too high to land or too far out. The third plane and all planes after seem to just last a lot longer and they stay in better shape. ARFs don't last as long as a kit build but even they last a bunch longer.
I fly a lot of old school pattern planes and the Kaos has been my favorite over the years but the Ultra Sport is the grand son of the Kaos so that is another good choice. The old pattern planes make me look a lot better then I really am. Just so many planes to choose from so it's up to the beholder to see what they want next. I'm building the Dirty Birdy right now to replace my poor old Kaos, the DB is another Bridi design, sleeker looking then the Kaos and will hold a much better knife edge line. Blue Jay had most of the Bridi kits and the pric is right. Problem is these are old school planes and old school builds, a lot of carving and sanding compared to the newer kits and the instructions do leave a lot to be desired. Not for newer kit builders. They really are great planes though and built like tanks!!
