CA has a couple of promesing planes. I've seen the Epsilon 90 in action, and it flies great.

A friend of mine had the CA Epsilon 90, and is now flying the Venus II... He really likes the Venus, and gives it the thumbs up, powered by an Ys110.

Did you have any preferances on kit, ARF, glass or wood?
As builders kit, MK has a few great models..
Also, Fliton does have a couple of good looking machines. And the Hyperion Katana F3A 90?
I would also try to get hold of Hirobo retailers.... (Astral XX, Aries etc..).

Good luck anyways. There are a lot of good 90-size planes out there.... Check out some Japanese sites... Those planes are hard to come by, but most beautiful machines...
