3D model description

Toroidal triblade propellers for tiny whoops with a diameter of 40mm (1.57 inch) and two different hub sizes. The design was tested and pictures are inlcuded here. The propellers performed well and some flight footage will be published here soon. The center of mass (black & white point) is shifted towards the middle for the well known problem with drag on toroidal propellers. This is shown in the attached construction picture. The center of mass is also exactly on the middle line for each blade and exactly in the middle of the propeller.
