John,
I stand corrected....too many Pints of the foaming Ale I presume!
I found a CG chart for the A Model Wokka.....which shows a 48 inch travel at 27,500 Pounds MAUW and 23" at 33,000 Pounds.
I know you can set a full pallet (about 4,000 pounds) of Cememt Mix on the Ramp....sling a huge Yellow Concrete Mixer bearing Blue Air Force markings and still have sufficient cyclic control. As haste was of the essence....and it being Midnight at Bien Hoa AFB....there was not a lot of planning involved.
Having a Cargo Winch, Ramp with extensions, and a Cargo Hook made Midnight Requistioning great fun....with virtually unlimited possiblilities. Having the ability to carry an M-151 Jeep with FM Radio for scouting and coordination opened up places not usually accessible.
The trick was to get the Yellow covered up with Olive Drab and place Black US Army numbers all over the Mixer.....and dryed before OSI, CID, or the MP's made it to our unit area!
