Finally after no info from Nitro Models I was directed to a website with a calculator to figure where the CG should be.

At the fuselage it said 3.5 inches, which if you draw a straight line out to the wing tips, is at about the 2.2 inches stated in the instructions.

After flying it, I moved the CG to be a bit more noseheavy. It flies like a dream, and I now have over 20 flights on it.

A great Little model. takes a bit of power on landing to keep from tip stalling.
