Here's how I solved the 360+ degree rotation. I made a pattern of the teeth on the turret ring gear and then cut new teeth in the ring gear where the tab was to stop the turret from rotateing any further. Now my turret can keep on rotateing till I either stop it or it twists the wires off. I re-made a quick movie with my Kodak Easy Share digital camera not the best for shooting video but you can see the turret in action. And the turret motor does have enough strength to bend the antenna over since I moved it to the correct location. In the pic of the template I included a section of tape measure to show the actual size of the pattern

I will be doing this modification to my PzrIII L as well... Nice to fool the other guy into thinking you can only rotate the turret so far when he sneaks up behind you and you rotate and whammo you nail him
