Having the same issues as blub01. For instance, I built the VTOL in SPH with older version of IR (under 0.20 I believe, don't remember exactly). While I haven't messed with Rotatrons in new version it worked just fine and symmetrically, but when I opened the new position editor (AKA Servo Configuration) the mirror symmetry was gone. If I was setting limits to one of them, the other one was rotating a different direction regardless of inverted or up-inverted axis. IR under v0.20 had no such issue, it worked just fine. Now what I have to do is to place them separately, trying to keep the symmetry manually. Really grinds my gears. Please, fix. http://i62.tinypic.com/r2ne9u.jpg/ Full res The mod is great tho
