b) Motor Function (Mode 2)
• Slide the control lever for the engine speed (also see figure 1, item 12) to the bottom position (motors off, see figure
11).
• Start up the transmitter and then the model (connect rechargeable battery).
• Hold the model tight and push the control lever for the motor function slowly from the bottom to the top position (see
figure 12). The rotors 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.
• Perform a brief motor test and check the run of the two rotors.
• For the following tests, observe that the motors are deactivated. Slide the control lever for the motor function (also
see figure 1, item 12) to the bottom position (motors off).
• Disconnect the flight battery from the model again and switch off the transmitter.
To protect the flight battery from deep discharge, the motor electronics will switch off the motors when the
discharge end voltage of the rechargeable battery is reached. The LED in the model flashes. Touch down at
once after the motors were switched off.
if the model is relatively far away from you, you can return the model for touch-down at low motor power. For
this, briefly push the control lever for motor control to the bottom position (motor off) and then slowly move
the control lever forward until you can land nearby with reduced motor output.
Flying on with reduced power after the first motor deactivation must not take too long, or the rechargeable
battery will be deep-discharged and permanently damaged (power loss).
