RE: Giant Big Stick with zenoah 38?
I initially flew mine with a US 41 which I am sure was quite a bit heavier than the G38. It flew great with a little tail weight added. There is plenty of wing to compensate. I now fly it with a G26 and I like it even better! Not quite as much vertical but who cares, I don't fly helicopters anyway! It is the plane that I never get tired of!
