Routing the receiver’s antenna
The receiver and the antennas must be positioned as
far away as possible from any drive components. If
the model’s hull is made of carbon fiber material, the
ends of the antennas should always extend outside
of the hull.
The orientation of antennas is not critical.
Nevertheless, a vertical (upright) installation of the
receiver’s antenna(s) is advantageous.
Servo installation
Always mount servos with the rubber vibration-damper parts provided. This is the only way of en-
suring some protection against excessively strong vibrations.
Installing linkage
Linkage must be installed so as to ensure unhindered and smooth movement. It is particularly im-
portant that all rudder levers are able to move to their full limits and are not blocked mechanically.
In order to be able to stop a running motor at any time, the linkage must be set to ensure that the
carburetor tap is completely closed when the joystick and trim lever are brought into their end idle
positions.
Pay attention that no metal parts rub against one another, e.g. as a result of moving the rudder,
of vibration, rotating parts etc. Metal-to-metal contact causes ‘static’ which can interfere with the
correct operation of the receiver.
Transmitter antenna orientation
The patch antenna is integrated in the rectangular front panel of the transmitter. This means that
‘aiming’ the transmitter at the model will have a positive effect on reception. However, when two or
more pilots using 2.4 GHz remote control systems are within 5 m of one another this can lead to
return channel overdrive which, in turn, will trigger a range warning much too soon. Increase your
distance between one another until the range warning ceases.
Pre-start checks
Before switching the receiver on, ensure that the throttle control is in the Stop/Idle position.
Always switch the transmitter on first and then the receiver.
Always switch the receiver off first and then the transmitter.
WARNING:
If this sequence is not maintained, and the receiver is still switched on when the
corresponding transmitter is switched to the ‘OFF’ position, then the receiver may
respond to other transmitters or general radio frequency noise. This can cause the
model to execute uncontrolled operations that may cause personal injuries and/or
property damage.
