In the plans for the 3DFoamy Pitts, does the black and white circle represent the recommended CG?

Does it look like I have the battery and receiver in approximately the right position? It balances where the trailing edge of the center strut enters the upper wing (which is in line with the black and white circle, and practically in line with the leading edge of the lower wing).

I'm going for my maiden flight this afternoon, I hope.

I found out that I really had to tighten up the pull-pull lines if I wanted to get 3D travel on the tail controls. This makes it hard on the elevator design if you just use packing tape and light ply for the hinge. I plan to use CA hinges on all control surfaces next time. They really worked well on the ailerons and they help zero the control surfaces perfectly when you release the sticks.

Thanks,
Clay
