I've been flying mine more now that I have retracts that work. Mine weights 15 lbs 14 oz with the tank empty. I tried to build it as light as I could and still build stronger gear mounts and add flaps. No glassing, except in the gear area, only repainted the bottom. No retractable tail wheel or cockpit. Built it more to fly and not for "Scale Masters". But I can see that other planes on this thread are truely works of art and can compete with the very best scale planes out there. I test flew at 135mm cg and was tail heavy. Now its 120mm cg at the root and flys good. Diffenently not nose heavy. Powered with a 25cc conversion which is adequate but not over powered. Flys scale. I would not recommend a test flight with the cg further back than 135mm, but maybe I just don't like overly pitch sensitive airplanes.
