Section 12: Recommended Center of Gravity (CG)

An important part of preparing the aircraft for flight is
properly balancing the model. This is especially important
when various engines are mounted.
Caution: Do not inadvertently skip this step!

Step 1
The recommended Center of Gravity (CG) location for the
5
Fokker D.VII is 3 / inches (92mm) behind the leading
8
edge of the top wing near the cabane struts or at the wing
tips. Mark the location of the Center of Gravity on the
bottom of the top wing.
Note: The Center of Gravity can
also be measured at the wing tips
using the above measurements.
Note: If your balancer hits the bottom
wing, it is best to balance your model
with your fingertips at the wing tips.
Note: The range for the Center of Gravity is
3 3
3 / – 3 / inches (86mm–95mm). You can
8 4
change the Center of Gravity within this range
based on your personal flight preference.

Step 2
When balancing a biplane aircraft, it is best to balance it
upright as shown in the photo.
Place your aircraft on a balancing stand, or lift the model
with your fingertips, at the marks made in the previous
step. The aircraft should rest level or slightly nose down
when balanced correctly. If necessary, move the battery
pack or add weight to either the nose or the tail until the
correct balance is achieved. Stick-on weights are available
at your local hobby store and work well for this purpose.
A weight box has been provided for the weight that is
required to achieve the correct Center of Gravity. Because
of the scale nature of the Fokker D.VII and the short nose
forward of the CG, weight will be necessay to balance this
type of model. Use the supplied weight box to place this
additional weight.
