Battery positioning
The Saab Draken has an adjustable battery tray system that makes adjusting the Center of
Gravity very easy. Secure the battery to Battery_Tray with velcro (strong adhesive) or use hot
glue.
Slide the battery tray and battery into the slot in Fuselage_07 and feel how the battery tray
can be locked in three different position. Choose the best of the three positions to balance
the model at the Center of Gravity indicated underneath the wings as two raised dots. When
the best of the three positions has been established, cut a piece of EPP foam or similar that
will fit the space between the battery and the end wall of Fuselage_07. This is just to ensure
that the battery will not shift backwards during launch.
