My flying buddy has been flying the snot out of his Avistar. He got a ARF Kaos. We got the wings hinged and glued together. I also had him fuel proof the motor area which was not in the instructions. It had bare balsa showing. But it went well.

He already went and ironed the covering down as the instructions state. Although there was only one little wrinkle on the rudder. The covering looks great.

Cant wait to get mine. But working on his is a blast. Good practice for putting mine together.
