Sounds like a great setup. Others can chime in on the engine 'cause I know nothing about Saito. That plane is a little tough for a first timer to handle, but with your RC experience I think you will love it. It's fast and looks great ripping by in the sky.

Even with your experience it's best to get on a buddy cord with an instructor. Have someone fly it, trim it out, check it over, etc. then take you up on the cord. You will have lots of fun.
