I enjoyed very much reading this thread about one of my favorite planes. My Smith Miniplane had a re-maiden this weekend after 15 years. It was completely destroyed in 2000, and a friend of mine rebuilt it beautifully. Despite the terrible pilot, the biplane flew great. It is powered by an OS 46AX using 11x7 prop. The only problem is the tendency to climb whenever I add power. I think IŽll add a little down thrust.
Regards.
