Homebuilt - good story - hat's off to you -an almost-complete hydraulic loss on the '8 is more significant than loss of the green system on an Airbus, (A320/A330/A340 series). Well done. How heavy were the controls?
Cable-driven servo-tabs on the ailerons/elevators, electric trim for the horizontal stab, and cable-driven rudder and the aux pedestal by the oiler's panel behind the F/O that had an Alternate Hydraulics lever..., IIRC? - loved the airplane.
