Drill 5 mm access hole into the additional ballast compartment in the fuselage (refer to the building plan). Support the wing of the model with your fingertips in the centre of gravity position (the point marked by an arrow on the fuselage plan). The fuselage should be level. If the nose pitches up, put in as much of additional ballast (not supplied in the kit) as necessary. You can use pellets, small screws etc. Once satisfied, cover the hole with a strip of clear sticky tape.
