Default RE: determining the c/g pre-flight

Jimmbbo,
Found the thread with the link to the spread sheet that computes c/g's. My plans suggest starting at 3.75" back of the le. And to go no further back than 4.125". The c/g calculator came up with 5.21" back of the le or 45.42% mac. I think to error on the side of caution I am going to start with the plans recommendations. I'll toss it around by hand and see what it looks like.

Does anyone recall a thread on tuning a cg that used a method involving trimming the plane using inverted flight?
