Very interesting, Matt, I'll certainly take a closer look at this system, probably order one, as ONE locked up servo on a dual servo Hawk stab. for example, locks up the whole thing, meaning very little redundancy.

The other possibility with a common arm, or with the SWB system, is to have normal stab. or surface travels at low rate and if one servo fails causing reduced travel, then switch to high rate activated by a mixer switch restoring all or most of the pitch response. Just enough to get you home.

And talking of servos, has anyone any experience with the new 6000 series metal cased v. powerful JR servos ?
