Hi, I am building an aircraft and want to be able to control the rotation of the flaps/aierlons on the wings. So far my solution is to just parent an empty to the flap with rotation contraints. This allows me to rotate the flap simply by rotating the empty. However, I want to be able to have the flap on boths wing syncronized so I can rotate them simultaneously when a mirror modifier is in use for the wings. Problem is they are obviously at different orientations (angles) from each other (see pic). So the flap rotation on one side of the mirror rotates fine, but the other side the rotation is out of whack (I assume because the flap axis is different).
Any ideas on how I might accomplish this??
