The servo for my roll axis stopped working. It now has way more resistance than it used to. It didn't sustain any trauma that I know of. It was working fine, I packed it into the backcountry in a backpack and when I reassembled my Cinestar it didn't work. The Radian is supplying it power, I plugged in an old Savox servo and that fired up. Any ideas on what may have happened? Is there any hope for it? Can it be repaired or should I get a new one? It's not that old it has just a handful of hours of use.
