I spoke to a few ec engineers, the dual hydraulics will not eliminate jack stall, it has 2 pumps not 2 sets of servos. they said the servos were designed that weak on purpose, seemingly a stronger servo would shatter the star flex in such a high g manoeuvre.
Why anyone would want to demonstrate the thing is beyond me, isn't that like demonstrating dynamic roll over ? You don't have to experience something to know to avoid it!
