After seeing stuff from volvospeed and yellowshaker i am embarrassed to continue but i will. here is the traverse mechanism. It is a low profile servo with a standard ball and socket arm but i use a camera controller circuit from Dinoysus Design. This adapter allows the servo to move slowly and stays where it was positioned last. I have these in my Elefant and my Panther F. I included reference info for the adapter in case anyone wants to try them. I also finished mounting the IR receiver so I can now begin to finish detailing, final paint and get to war. I have been doing interim testing so it should complete pretty quick. BTW i blasted off all the grinding and sanding dust.
