Hmmm I'd say the Bridi Kaos is a fine flyin plane. It's my third plane. Plenty light for the size. I got the prebuilt and picked it up cuz I'm with in an hour and a half drive of his shop. Got it at Thanksgiving, flew it a month ago! Long turnaround but I was deciding on the power plant. Got the Saito .72 first, would have been fine, but then scorpionjack got me excited about a YS 63, but then I got a good deal on an OS 91 FX. So I'm really happy now with a 6 pound plane with some balls! Goes up vertical at half throttle, with over a 2:1! Not really flyin it like a pattern plane right now but I'll get to that, I'm just having a blast with this plane!
