Balancing stand (optional)
An important part of preparing the aircraft for flight is
properly balancing the model.
CAUTION
:
Do not inadvertently skip this step or
property damage and injury could occur.
1. Assemble your model in preparation for flight,
making sure the wing is on securely and the motor
battery is installed as instructed in this manual.
2. The recommended Center of Gravity (CG)
location for your model is 2.75 to 3.00 inches
(70.0 to 76.0mm) back from the leading edge of
the wing 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.
Balancing Stand
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.
