Help! Got Pizazz at swap meet, installed all gear need to know where to check c/g?

I've got mine balanced just at the trailing edge of the checkerboard ultracote. That's just about 1/8" back from stock. I put my index fingers half on red, half on checkerboard at the wingtips, and it's perfect. I plan on moving it more as I get better. Hope this helps!

3 1/4 to 3 3/4 from the leading edge is in the instructions. I think my checker board is on crooked, my measurements are a little off.
