Looking for a good Float Plane
Check out Unionville Hobby kits, available through Great Hobbies. Prices are in Canadian dollars, so great deal. I have 7' Norseman, built but haven't flown yet. A friend had one and was very happy with it. I enjoyed building the Norseman, light construction so will fly well on .90 4C.
If more interested in ARFs, I also found someone on RCU that offers ARF's of same planes in same sizes. His website was something like deHavillandmodels.com.
