The new elastomer nosegear for the -7A has a little back-and-forward pivoting movement when off the ground. This pivot accounts for a 1-3/8" difference in measured nosewheel arm, in other words, when on the ground, the nosewheel is 1-3/8" forward of where it is in flight, relative to the datum. Which arm makes sense to use for the purpose of weight and balance? Since the purpose of calculating the moment arms is to compute the C.G. in actual level flight, I would assume the correct arm measurement is with the nosewheel hanging down as if in flight. The only problem with that is when weighing the plane, the nosegear is obviously in it's pivoted-forward on-ground position.
Strangely enough, neither of my measured nosewheel arm length comes even close to the example numbers in the manual. Perhaps the examples are based on the old style nosegear.
