i'm going on 2K hrs on type so i have done a number of hydraulic failures in training. i have never had a real one, but in my experience, the astar without hydraulics is entirely manageable. it is a lot of work and may involve getting the appropriate knee involved in order to some of the load of the shoulder, arm, wrist, and hand.
whether or not the hydraulic system is adequate for the job has been debated many times before, but if you are not doing something that you should not be doing, then servo-transparency or jack stall is very unlikely. most of the time i have in this type is doing production longline work all over North America, and in the course of normal duties i have never experienced it.
the design of the system may leave something to be desired. keep in mind i am not an engineer, but there is something about running a constant pressure pump in a closed system that seems questionable. also, the belt drive might be considered "fromage" but again, it has served me well enough.
fly safe.
