The directions are poor if you even want to call them directions mostly pictures. All it says is 430mm from the leading edge of the canard wing. Its just an illustration no words. I was watching this thread:

This thread kind of confused me some had fuel some did not. The instructions from the GP CG machine said if the tank was in the rear to put fuel in the tank. Which makes sense . If I CGed it with an empty tank the plane would be tail heavy until I burnt off fuel. I am new but have mostly bought planes used that have already been built.
The fuel tank is in the back of the plane about 6 inches give or take from the CG.
I really like this plane and would hate to plant it.
Thanks
