7. Check the movement of the aileron using the
transmitter. When the right stick is moved left, the
left aileron will move up and the right aileron will
move down.

The first part of the Checking the Control Throws
section details the basics for setting the control
throws. We at E-flite have also detailed how to
measure the control throws if this is the first time you
have set the control throws for a model aircraft.
1. Turn on the transmitter and receiver of your
model. 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.
Note
: If using the DX5e you will find
your control throws to be slightly
different than listed in the manual on
both high and low rates. The control
throws will work fine as delivered by
the DX5e on both high and low rate.

These are general guidelines measured from flight
testing at E-flite. You can experiment with higher rates
to match your preferred style of flying.
If using a computer radio, the Travel Adjust and
Sub Trims are not listed and should be adjusted
according to each individual model and preference.
