In the early days, Air Log ordered S-76's with no SAS system as they sent all theirs down to Texas for installation of the Sperry Helipilot systems.
The Aircraft were delivered in West Palm Beach and were either flown to Texas for the Sperry install or put to work until that could be arranged.
Air Log, true to GOM standards, operated the "Bare Hares" VFR until they could obtain a slot at the Dealer for installation of the Sperry System.
The 76 with no SAS system is a hand full but is quite flyable.
With a Sperry System installed and operated in ATT Mode....with Force Trim ON.....using the Cyclic Trim Switch or Force Trim to reset your Datum works fine.
Sir is right in what he states.
