Built from RCM plans last winter. 5 1/2 pounds Saito 91S it all adds up to fun. I used an oversized canopy to help knife edge. This is my fifth and lightest (original) Kaos. I built and flew the one previous to this in 1975. I'll use a foam wing on the next one I build. Why? Because cutting out the ribs is a pain and at 5 1/2 pounds I can afford the weight gain of a foam wing. The modern vs. old debate has been going on about the Kaos since the 70's. In the 70's people flying Mach 1's, Sweatators, T2A's, Cutlasses etc said the same thing about it being dated. Don't listen to it, its a bunch of rubbish. Build one and fly the pants off it. Old design or not, its a great flying airplane and it's hard to get more bang for the buck.
