RE: second plane
fly dat, Now, on a serious note.....I agree with the Sig 4-star, Goldberg Tiger, or a Stick as a second plane. As stated a 60 size is a good idea, bigger is better. I would also suggest that a move to a taildragger would be a valuable learning experience while your at it. The Tiger or the stick could be built as a tricycle-gear to start with then later converted to a taildragger if you want to do it in steps. The 4 stars are taildraggers only but are very nice first low wing planes that you won't soon outgrow.
