I had an Ultimate Kaos back in 1996 and flew it with a Hanno. It was a great flyer with that set-up. The OS 61 SF-P will be a great match for the airframe as well. Also, for a light powerplant, you might consider the Evolution 60NX (not the 61). I'm putting one in a World Models Intruder. It's a 60 in a 46 crankcase.
