I believe so, although it was a combined input ie yaw to pitch value + airspeed data transducer input. Of course the mixing unit was designed for 16850lbs or thereabouts. I'm sure you can remember the demonstration of the Heading Hold micro switches on the pedals,, and how at 16850 GWT you could lift vertical without the need for any compensation of Translating Tendency, Heading or pitch. Great Mixing!! But the Stabilator is a seperate dynamic function than the Mixing unit but addsto it's performance! When they worked the bugs out, it worked great! A few of my buddies became the statistical dead test pilots may they RIP. Price of technology is very severe sometimes, and the UH-60 extracted it's toll on life in it's advancement. A terrific Helicopter with very few competitors, if any!!
