6. Lightly sand the inside edge of the canopy at this
time as well. Use care not to over-sand the edge
and get into the clear area of the canopy.
7. Use canopy glue to glue the canopy to the
canopy hatch. Use low-tack tape to keep the
canopy in position until the glue has fully cured.
8. Remove the lines made by the felt-tipped
pen from the fuselage using paper towels and
rubbing alcohol.
Center of Gravity
An important part of preparing the aircraft for flight is
properly balancing the model.
Caution: Do not inadvertently skip this step!
The recommended Center of Gravity (CG) location for
your model is 3
1
/
2
to 3
7
/
8
inches (90 to 98mm) 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.
When balancing your model, support the plane
inverted at the marks made on the wing with your
fingers or a commercially available balancing stand.
This is the correct balance point for 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 forward in the
battery area inside the cowling.
We suggest a Center of Gravity of 3
1
/
2
for precision
flight and 3
7
/
8
for 3D flight. Some have found the CG
range to be a bit broader and is a personal taste and
feel. You may explore the range and find the location
that works best for you.
After the first flights, the CG position can be adjusted
for your personal preference.
Control Throws
1. Turn on the transmitter and receiver of your
Extra 300 32e. Check the movement of the rudder
using the transmitter. When the stick is moved right,
the rudder should also move right. Reverse the
direction of the servo at the transmitter if necessary.
2. Check the movement of the elevator with the
radio system. Moving the elevator stick toward the
bottom of the transmitter will make the airplane
elevator move up.
3. Check the movement of the ailerons with the
radio system. Moving the aileron stick right will
make the right aileron move up and the left aileron
move down.
4. Use a ruler to adjust the throw of the elevator,
ailerons and rudder. Adjust the position of
the pushrod at the control horn to achieve the
following measurements when moving the sticks to
their endpoints.
