Advice for building and flying the avistar
Just like tsawyer148 said, this is a pretty easy build. It was my first ever and other than adding strength to the firewall, and landing gear, mine when together in a snap. I will admit, however, since it was my first plane, I read each step at least 3 times.
One recommendation though, after you mount the engine and prop, check the engine deflection to the right, and the incidence of the engine as well. The deflection to the right on mine was fine, but when we checked the engine incidence, it was 4* down. It has between 0 and 1/2* down now, and it is a great plane for a trainer.
