You should be able to turn on/off the transmitter and if the failsafe is really set to HOLD last position (and not USER defined) then the servos should stay put. You should not see any amount of movement. Unless you deliberately changed the RFU's settings the failsafe defaults to USER defined with preset positions at 1500us. It is recommended that you do the live-active failsafe setup. You do that by powering on your system so you can move the servos and then press and HOLD the button on the RFU until the LED started flashing red/green. You will have about 7 seconds to positions the sticks and switches on the transmitter where you want them during a failsafe condition. Typically this will be all neutral sticks. The purpose of failsafe is not to save your aircraft - it is to provide you with some insight of where the crash will most likely occur so that people can be moved out of the way. We typically provide a small amount of up elevator and rudder to cause a deliberate spiral pattern during a failsafe condition.
The RFU works down to 2.1v, so the voltage level you are talking about will not affect it.
great inside as usual - thanks a lot
the more i am looking into different RC systems the better the XPS system looks. how could it have disappeared? i listened to the AI story and the Graupner (i am german and that i why i love my multiplex EVO) issues - too bad this happened.
i did not change the failsafe conditions and subsequent power off tests dis not show the movement.
anyways one last question (that could be a lie) - do you think i should be able to make the Spektrum SRXL2 DSMX Remote Serial Telemetry Receiver, SPM4651T work with the x10+ v2?
i did spend hours and it did not work. i programmed the x10 to input mode 3 flashes and tried all 4 binding modes to no avail. the SPM4651T was bound to my tx16s with DSMX protocol.
here a link to my various attempts

here comes bonus contribution.
i scoped the X10 signals and other than channel one all look really bad

CORRECTION and apology!
please again take a look at the link with the scoping signals. all looks good. it was my fault to work with uncalibrated scope probes.
