Today I got the opportunity to check for CG. The servo tray is loose on the mounting rails and the engine is taped in place. This give me the ability to move things around to help establish CG. I added 2 oz. just behind the firewall. This will give some weight to play with plus the battery under the fuel tank. So I have a starting point. The plane, as is, weighs in at 5.5 lbs. Now I can permanently mount the servo tray and engine. I can start doing some work on this fuselage.
