I had the same plane many years ago. It was heavy, glassed and painted but flew well. Our field wasnt the longest but the plane had plenty of speed to fly. My engine was an OS 61, if I recall. Nothing super powerful.
Low speed stall, maybe and maybe not. The jug has such a large wing and a thick airfoil it provides plenty of lift. I'm in the camp that look farther into the details of your set up.
