I flew one in the 70's that I built from RCM plans. You can probably still get the plans there.

They are listed at http://www.rcmmagazine.com/store/sto...jTq59cfdM565T6

I flew mine with a SuperTigre .46 and it was just right. I think I ran an 11-5 or 11-4 prop to keep it slow.

I still have it and was considering flying it again when I discovered this thread just now. I have one photo from those days and will send more later when I round them up.
