RE: Vectorflight Edge 540 build
Welcome Sturtz, your going to love your new VF Edge. If you have any problems or questions during your build, don't hesitate to ask. There are a lot of good ideas floating around, and once your plane arrives you may have some to share with us.
Gary is correct about the elevator, it is very sensitive. Use the recommended throws and dial in some expo to soften it out and it will perform like a true master of the air. The 91FX will yank it around fairly well. I imagine it will weigh slightly over 8lbs when done, a perfect match.
