With the OS 160 twin on 2" dowel stand-offs, an onboard glow lighter stuffed next to the fuel tank and the receiver with 5 cell NiMH battery just aft of tank on floor (servos in stock location in tray), CG was exactly where the book says to start. Plenty of room to shift battery aft to make it a litle more tail heavy if necessary.

With the use of lighter engines like the Saito 120 - 150, some nose weight may be necessary to balance.

Plan on an all-up weight in the 14 - 15 pound range without all the extra weight I added.

Still very light for a plane this size.
