Actually, no it doesn't. All servos become undriven when they loose power - how else could it be? That fact that some fall by the weight of the surface on the ground depends on the surface weight, and also the type of motor and gear ratio in the servo - i.e., the amount of friction in the system. The only servo that will actually hold a position without power are those driven by a jackscrew, and I don't know of any of that type that are used in RC aircraft (and even in those, it really just a matter of a lot of friction in the gear train that is holding the position).

Yes, we are OK on that point : it's a matter of gear ratio, and I will add a matter of command ratio.
To JackD : +1 ! I like the way you do it and try to do the same, even if its not easy some times !
This last theory seems interresting : servos comming down as power decrease. This have to be dealed with the factthat that it was a gentle turn, not a violent one, so I'm surprise that all servos went down at the same time like it was a violent action that putting the voltage low....
It's not Doc House here ! It's more NCIS !!!
