Basic Settings of the Digital Trim
Before testing the control functions at the model, you must review the current position of the digital trimming or set it
correctly.
The remote control transmitter has four trimming buttons (also
see figure 1, item 5, 6, 9 and 11), with the help of which the
"electronic centre position" of the two control levers can be
corrected.
When the model tends to fly to the left all the time later, for
example, you may set the rudder wit the rudder trimming later so
that the model flies straight again.
The trimming can be set during the flight.
Every short push on the trimming buttons makes the remote
control issue a short signal sound that becomes higher or lower
depending on the movement direction of the trim button. If the
trim button is deflected and held, the sound is issued at a quick
sequence.
When the centre position is reached, a double signal is issued. The end of the respective setting area is signalled with
a longer signal sound. The entire trimming path is approx. 30 single steps.
Put all four trim buttons to the centre position now.

Checking the Control Functions
Before starting your model for the first time, you need to familiarise yourself with the control functions and test the
model functions.
Switch on the transmitter first and connect the flight battery to the model.
Motor Function
Attention!
Ensure that no loose parts, such as paper, film or other objects can be sucked into the rotor during this motor
test. Also make sure that the model is held securely during this test run and that no clothing and body parts
are within the rotation range or danger area of the rotor.
• Slide the control lever for the engine speed (also see figure 1, item 4 or 12, depending on mode set) to the bottom
position (engine off).
• Start up the transmitter and then the model (connect rechargeable battery).
• Push the control lever for the motor function slowly from the bottom to the top position. The rotor will start up and
increase speed depending on control lever position.
• When the control lever is at the top stop, the maximum rotor speed is reached. Then move the control lever back to
the bottom-most position.
