RE: Epsilon 60/90
I believe Rocco is at Aeroworks. I ordered my Epsilon 120 from him. They were backordered on the 90 so he offered me a discount if I would take a 120. HoooBoy! I haven't started the build yet. It is a big plane but everyone thinks highly of it.
I also wrote Marcelo at CA and he is very nice and helpful. He also gets in on the threads once in awhile too.
I'm sorry to hear that Aeroworks is not going to carry CA models.
