CAUTION
:
Do not inadvertently skip this step or
property damage and injury could occur.
When balancing your model, adjust the motor battery
as necessary so the model is level or slightly nose
down. This is the correct balance point for your model.
You should find the CG to be very close with the
battery installed as shown in this manual. Mark the
location of the battery on the battery tray using a felt-
tipped pen so it can be returned to this position, if it is
removed from your model.
After the first flights, the CG position can be adjusted
for your personal preference.
1. Attach the wings to the fuselage following the
procedure outlined earlier in this manual.
2. The recommended Center of Gravity (CG)
location for your model is 5

-inches
(145 to 155mm) back from the leading edge of the
wing at the root as shown with the battery pack
installed. Mark the location of the CG on the top of
the wing with a felt-tipped pen.
3. When balancing your model, support the plane
upright at the marks made on the bottom of the
wing with your fingers or a commercially available
balancing stand. This is the correct balance
point for your model. Make sure your model is
assembled and ready for flight before balancing.
If you have installed retracts, balance
your model with the gear down.
