E-flite Sukhoi SU-26m 480 ARF Assembly Manual
Control Throws
1. Turn on the transmitter and receiver of your
Sukhoi SU-26m. 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.

Measurements are taken at the inner or
widest point on the control surface.
These are general guidelines measured from our own
flight tests. You can experiment with higher rates to
match your preferred style of flying.
Travel Adjust, Sub Trim and Dual Rates are
not listed and should be adjusted according
to each individual model and preference.
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 (89 to 98mm) back
from the leading edge of the wing. Mark the location
for the Center of Gravity on the top of the wing next to
the fuselage as shown.
When balancing your model, support the plane
inverted at the marks made on the top of the wing
with your fingers or a commercially available
balancing stand. Adjust components as necessary so
the model hangs level or slightly nose down. This is
the correct balance point for your model. You might
find you may be required to add a small amount of
weight to either the front or back of the fuselage to
achieve the correct balance.
After the first flights, the CG position can be adjusted
for your personal preference.
