RE: A little SBus data for future users.
I think there is a lot of guff talked about servo amp draw on jets. As most of you will know, current draw issues with digital servos is a serious consideration with flybarless helis, particularly large ones. Big 3d planes can also draw a lot of current. interestingly, the biggest draw, short of a completely stalled servo, is when you get rapid direction changes of the servo, something that you have a lot in helis and 3d planes but nowhere near as often in jets. Jets do of course travel faster, so the air pressure at the control surfaces is going to be higher, but then jets should be using servoswith torquecapable of dealing with the sort of demands that this places on them so that they do not stall.
My suspicion is that most jets, in a normal flight regime, pull no more amps than a high performance glider, provided the control linkage geometry has been set up correctly and the servos are well matched to the size and performance envelope of the jet and the specific control surface they are having to move.
