b) Before operation
• Unroll the wound up wire of the antenna of the model to its complete length. The part that hangs
out of the model at the rear must neither be turned over towards the front and fastened to the
model nor cut off. The best reception results are attained if the wire hangs loose from the model
and is dragged during the flight.
• Make sure that there are no other models operated within the range of the remote control installation
and on the same remote control channel (transmitter frequency). Otherwise, you will lose control
over the remote-controlled model! Always use different channels if you wish to operate
simultaneously two or several models in the immediate proximity of each other.
• Check the function safety of your model and the remote control installation. Pay attention to visible
damages such as broken plug-in connections or damaged cables. All movable parts on the model
have to be smooth running, however, there must be no tolerance in the bearing.
The propeller and the motor are mounted at an angle when looking at them first. This is
not a manufacturing fault or defect, but imperative for aerodynamical reasons. For furt-
her details, see chapter 15. a).
• Charge the flight battery, which is necessary for operation, as well as the rechargeable battery
needed in the remote control according the instructions indicated by the manufacturer.
• As power source for the plug-in mains unit, use a 230V/50 Hz mains socket of the public mains
only. Never try to operate the device at another voltage.
• If batteries are used for the power supply of the transmitter, make sure that there is a sufficient
rest capacity (battery checker). If the batteries are empty, always replace the complete set, never
individual cells only.
• Before each operation, control the settings of the steering trim at the transmitter for different steering
directions and, if necessary, reset them.
• To operate your model, always pull out the telescopic antenna to its full length because otherwise
the transmitters exhibits a considerable lower range and the transmitter output is strained higher
than average.
• Always switch the transmitter on first. Only switch on the flight battery of the model afterwards.
Otherwise, unexpected reactions of the electric model airplane may occur and the propeller can
start to rotate unintentionally!
• Check the correct and secure position of the propeller before each operation.
• Make sure that neither objects nor body parts are in the rotating and suction area of the propeller
while it is rotating.
