RE: Total beginner questions
Welcome aboard, Spitfire1939.
The best builder in our club started about 8 years ago, building a Don Smith B-17 (138" wingspan) as his first build. This is an awesome plane, four Saito 91's, detail everywhere, flies very scale at about ¼ throttle.
Now, the build took him over 3 years, and along the way he built and wrecked two Duellists, a Four-Star, and flew some arfs and ½A planes. He completed his detailed C47 the year before he finished the B17, and it flew great too. He also built and sold some other planes (a T6 and my Jug come to mind.)
By all means, work on that Spit! Fly whatever you choose for your first plane. I suspect you'll reach a state of confidence with low wing taildraggers before you finish the Spitfire, and you'll hear more advice than you can sort out. Just make sure you enjoy the whole process!
Good work!
