Empty. The CG marked on plans is based on an empty tank.

Dave
I found this on another forum and built one to try.

Picture shows my Ringmaster Trainer being checked for CG.  Model is supported by the dowel and the pointer is also hanging from a loop around the dowel pointing at the CG.

Plans and instructions are found at: www.manateerc.com/CG-fixture/

4 sheets stored as .jpg files, two of instructions and two of drawings.
