Control horn and servo arm settings
The table shows the factory settings for the control horns
and servo arms. Fly the aircraft at the factory settings
before making changes.
After flying, you may choose to adjust the linkage positions
for the desired control response.
Linkage rods installation
Before installing the main wing, horizontal tail and vertical
tail, the linkage rods for ailerons, flaps, elevators and
rudder should be installed in advance.
Make sure the servos are in neutral position. Attach the
"Z" bend end of aileron, flap, elevator and rudder linkage
rods to the corresponding holes in the aileron, flap, elevator
and rudder control arms from the outside as shown (Please
refer to the control horn and servo arm settings sections in
manual ). And then install the ball buckle at the other end of
the linkage rods to ball head at each control horn on
control surfaces.
Check the C.G. (Center of gravity)
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. After the first flights, the CG position can be
adjusted for your personal preference.
1. The recommended Center of Gravity (CG) location
for your model is (125-135mm) from the leading edge
of the main wing (as shown) with the battery pack
installed. Mark the location of the CG on top of the
wing.
2. When balancing your model, support the plane at
the marks made on the bottom of the main wing with
your fingers or a commercially available balancing
stand. This is the correct balance point for your
model. Make sure the model is assembled and ready
for flight before balancing.
