Jerry;
We're flying with the CG pretty much in the middle of the "first flight"
box. My engine installation is a bit heavier, and the panel lighter, so I
had to add ballast in the nose for single pilot operation. IIRC; with the
ballast, the weight on the nose wheel is about 80#.
Al
Al - I am very interested in hearing responses to this question as I am
getting close to first flight.
How did your weight and balance turn out? I assume that you are not aft
loaded... How much weight do you have on the nose wheel under empty
conditions?
