Oh, goodness, if you want a Cub, build one. You don't have to fly it, next. In one of my clubs, the president's first build was a Don Smith B-17. He built others, and flew them, long before the Fortress was finished. Another member built a Cub first, but then built a Midwest AeroStar to learn on. He flew the cub second, but he doesn't like it as much as he likes his Super Sportster ARF.

Build what you want. You'll know when you're ready to fly it - but ask for assistance.

Good luck,
Dave Olson
