would that mean that the stalled center hub section is larger in autorotation, just thinking. nice looking ship with 5 blades from above
that’s normal. Since I just preflight an 169 and a 412, the lifting portion of the blade starts at about 1,6 meters from the axis of rotation. Leaving out the crude 206 and 212 where it’s optimistically closer (about a metre).
