FWIW, I recall a discussion where "the best servo for each surface" was discussed. It was found that the 285 wasn't the "best" for both tail surfaces; I think it was found that there was a potential to save a few grams of weight, and a little space by using some other servo. (I can't recall what the other servo was, though.)
It was pointed out that, in the event of a servo failure, it's easier to keep just one kind of servo on hand for replacements, instead of needing a spare of each type.
Any future builds will have either 285s, for full sized DLGS, or Dymonds for minis, so I can run 2S without a regulator.
