Id like to know where that formula came from. The height seems to be an arbitrary factor and drag on the wing is a multiplier, not a negative term, I just dont see the units working out.

It the wing was up 30 feet it would do more???? And if it is a torque factor, then it would be bad as it would tend to reduce the front down force. Not sure about the equations source. Where do you measure the height?? from the centerline? ground? surface it is mounted on????
