3 Rotational Degrees of Freedom Test stand

How I can make/download a support stand mechanism for an RC plane that will allow rotation of the RC Plane in all three axes?

Accepted answer

Is what you are looking for a way to 'mount' your plane and allow Roll, Pitch and Yaw? I would think of it this way: you can add one after the other to your design. I would start off with some form stand (perhaps an inverted U shape) and add a ball bearing (perhaps with a spring mechanism to return to zero) at its peak. That will give you the Pitch rotation. Then add to that a perpendicular bearing/spring that points 'up', this will be the Yaw rotation. Then to that one that points along the axis of the plane (i.e. 'forward'), this will be your Roll rotation...
The question beyond just putting this in CAD would be related to allowing limits both in terms of maximum values (stops on the bearing) as well as maximum rates of rotation (dampers). This can be a fun learning exercise...
