ifmu, when you say propaganda, it means that you dont believe what they are saying - a pox on you! Those guys who are working on the X2 are just like you and me (except they know what they are doing, mostly.)
Grav, the FBW control systems are hydraulic, the FBW works a dual valve on the servos.
To my knowledge, the full electric servos that have been propagandized on other aircraft have some real problems, and those programs are a bit behind, due to that. jamming and wear on the jackscrews is reported thru the grapevine.
