If I were you I would try and find a GP Super Kaos. IMO it is the best of the bunch. It is an original Bridi design, with the typical GP building techniques added. I have at one time or another had one example of every Kaos, or Chaos that Bridi has designed. The Utter Chaos, while an excellent flier has in my opinion some building issues that I do not care for.

I am currently flying a GP 40 size Kaos that is true to the Kaos lineage. I have a Super Tigre S45K ABC on it, and it is a blast. Like all the GP kits, it is a little over built, but IMO the Utter Chaos goes to the extreme in the other direction.

You will not find many planes that are more honest than a Kaos.
