I did the exact same thing as you are and I built a
Bruce Tharpe Engineering Flyin' King. It's big. I've got a Saito .91 on mine. I should maiden it either later today or tomorrow.
The build was easy, though I made quite a few mistakes, all my own fault. The materials supplied are fantastic. If you need help Bruce is always available. He replies to e-mails within about 8-12 hours usually and will answer the phone all day.
This would be my suggestion.
