Poor training system. Doesn't fly well at all. I used to dread them coming to the field when I was instructing primary instruction. The predecessor Avistar was a far better trainer and flying platform. If you don't fly, you don't know it doesn't fly well. And, they are never RTF!!! Always takes at least an hour or more at the field. I had one student show up still in the box and thought he could fly it right then and there! IMHO........junk. Radio and engine are good.
