What will this do to the loading of the aircraft?


Fuel weighs more than air and wood. At full fuel your wing loading will
increase, with all that that entails.

True, fuel is heavier than air or wood however there's a lot more to this
than weight of fuel. Assume you've got a fuel load of 120 pounds. If that
fuel was in the fuselage that weight is supported by the wing attachment
bolts. If that fuel was IN the wings, then the wing attachment bolts are
not supporting that extra 120 pounds in the fuselage. This is the reason
most larger aircraft are designed to carry most of their fuel in the wing
structure. Less stress on the wing attachment bolts. The WING LOADING is
the same assuming the weight of the fuel remains the same. Wing Loading
is simply the weight of the aircraft divided by the area of the wing.

All true, except I thought he said he wanted to add fuel in the wings, not
remove the fuselage tank and put tanks in the wings...
