How about the DC-3/C-47 Gooney Bird? Can't get much lower or slower. Still have fond memories of riding in them.JimREAL airplanes have big round engines.......

The MAAM C47 works ok on my PC if I use the default DC3 visual model. It only requres a little tweaking for wheel height, eyepoint etc.of course the virtual cockpit layout doesn't match the 2d cockpit.My favourite propliners are:FSD CheyenneDC3Miltons Dash 7Lagos Twin OtterB314 Clipper
