I've got various DS4xx cyclic servos that go with FBL T-Rex 450 Pros.
I've got 3 new DS410s (not Ms), and two of them have got a lot of lash in the gears - but the 3rd doesn't. A new DS415M (interesting spec & price) doesn't seem much better.
I must have a look at some of the other DS410Ms I've got to see what these are like. However, I don't remember noticing it.
I'm guessing that this much lash must effect how they fly, and setting up the FBL head accurately. This is particulalry irritating, as the (RJX) head and (Align) swash between them have negligible slop - but the servos lead to quite a lot of play.
Any similar experiences ?
I guess Savox are the same ?
