Default bobcat setup help

does anyone have the recommended throws, CG, and AOA while sitting on the mains. I read the bobcat thread, it seemed CG was around 10.3 inches behind the LE. is that the final best CG? the nose gear was tweaked on mine and I'm replacing it, I have an incidence meter in the wing and was wondering what should I set it at.
tonights the last day before Sunday I have to go through the plane, so any help is appreciated.

here's a quick run down of my set up
ailerons 1/4 up/down low rates- max throw high
elevator 3/8 low- max high
rudders 1/4 low- max high

CG 10.75 from the LE
AoA 2.5 degrees+ on the mains

all that's left is a good range check, and some taxi adjustments. (and good weather)

I hope you see this before you go to the field.

Move that CG to 10.3 max, you are headed for trouble at 10.75

I'll have to double check my measurement. I flew it today. the elevator was sensative at low speed, but not bad enough I couldn't control. I ended up turning the ailerons down to 1/8 deflection on low rates, that tamed it down. my origanal set up was too much throw for just flying around. the roll rate was pretty impressive. I never tried the high rate, I will remove some throw from the ailerons before I do. I used the rudder and elevator on high rates for the maiden and they seemed pretty good where they were. once trimmed out the plane flies inverted nice.
