Well, I tested both of the servos again today, and one of them konked out after 1-minute...plugged the other one in on that side and it worked fine. Checked and re-checked the bad one, and still no workie.

Rather than ask for another replacement, I'm just going to buy a couple of Hitecs, and be done with it.

Mine is still going strong!!  Bought another battery ( 1800mah, 3cell lipo) over the winter.  Flew it off the snow once with no problems.  It's so light it hardly leaves a mark.  Also bought a Great Planes PBY Catalina and just ordered 2 x 400 size Exceed motors and 2 pre-wired 40amp ESC's from Hobbypartz.com.  Hopefully it will be just as good or better.  Regards.  Mark
