Hi. I've used FSDS for years, but decided to try Blender recently. Everything is going well (I like it a lot) but I'm stuck at getting animations along an oblique angle to work, like the aileron in the screenshot. In FSDS I could easy move the axis to the desired spot along the forward edge, and use shift-lmb in rotate mode to rotate the axis only, to match the angle of that edge, with predictable and acceptable animation results. Do I need to be looking at using Blender "constraints" and/or "armatures" to make this work, or is there a simpler solution? I've done various searches on this to no avail. Thanks for any help!
