Hey gang, wondering if somone can help me modify the Extra 300s from Add-ons 4 to match my plane.

I have the CMPro Extra 300s 1.40 72.5"

Specs

Span 72.5"
Length 64"
NACA 0014 Airfoil
Listed wt 11.6lbs
Wing area 54dmSq Couldnt seem to get a conversion correct Guessing ~800sq in?
31-34oz sq/ft

I'm wanting to have one as close to mine as possible, and I wanted to be able to try different motors, I'm considering a 1.60FX atm

Thanks for any help
