e) Connecting the Flight Battery
Slide the pitch function control lever (see figure 1, item 11)
and the trimming slider for the pitch function (see figure 1,
item 12) into their respective lowest position at the transmit-
ter.
Then switch on the transmitter and connect the flight bat-
tery using the BEC connector (1), which is protected against
polarity reversal, to the receiver/controller component's (2)
connection cable.
After connecting the flight battery, the receiver/controller
module (3) then carries out an internal alignment that lasts
for approx. 5 seconds.
While this is going on, the red control LED (4)
on the top of the receiver/controller component
flashes red. The helicopter must not be moved
during this time.
Once matching is complete, the two servo levers (also see
figure 23, item 4) of the rotor control also move to neutral
(centre position) and the control LED is permanently green.
Attention!
If the control LED (2) changes from green to red
during flight, the flight battery is almost dis-
charged.
When the LED starts to flash red, land your
model immediately to avoid harmful deep dis-
charge of the flight battery.
f) Basic Information Relevant to the Control of Model Helicopters
Before operating your model, you should get to know the available control options first in order to be able to safely
control the model. The double rotor model helicopter is controlled via the two control sticks at the remote control
transmitter.
The functions described on the following pages are available.
