We balanced it and with out fingures on the molded points on the wing, the nose hung down just slightly. He had a lipo battery in there pushed up against the spectrum rx. The control surfaces were behaving correctly on the ground - just couldn't figure it out??
Dave -

Just have him move the battery 1-2" forward, that should take care of the issues. My FJ was also a bit tail heavy, even when balanced as per Multiplex's recommendations. I know the classic signs of a plane being tail heavy are sensitive elevons -- even the slightest movement will cause the FJ to change direction sharply. However, my FJ still flew quite well even when it was slightly tail heavy.
