RE: CG Measured With or Without Fuel?

If the tank is in front of the CG... check with tank empty. (90% of RC models... including yours.)

If the tank is aft of CG check with tank full. (some pusher designs.

The Dornier "push-me-pull-u" (what was that fighter?... prop on nose and prop on tail.) forward tank empty, rear tank full.

If tank is on the CG... it really doesn't mater.

Balance it for worst case aft CG. and the CG will never get worse after take-off than where it was when you balanced it.
