Connecting the BEC plug and socket, as shown in the picture, switches the receiving
system on; if you now switch the transmitter on, the receiver is automatically bound to
the transmitter, and the four RC functions - aileron, rudder, elevator and throttle - can
be checked.
Checking the control surfaces
The transmitter sticks are arranged as shown earlier: the right-hand stick controls
throttle (motor speed) and roll (aileron). Stick back (towards you) = motor stopped;
stick forward = full power. The left-hand stick controls elevator and rudder: pulling it
back (towards you) = up-elevator, stick forward = down-elevator. Check the control
surface neutral positions, and adjust the trims on the transmitter if necessary until
they are exactly central (neutral). This is very important, otherwise the model will tend
to veer off to one side, or climb / dive steeply. Pressing the left-hand stick once
reduces the control surface travels to around 50%; we recommend this setting for the
first few flights.
Changing the transmitter mode
If you wish to alter the transmitter mode, unscrew the aerial retainer on the back of
the transmitter, rotate the aerial through 180°, an d fit the retaining screw again.
Flying
Wait for a day with little or no breeze. Prepare the model completely, ready to
fly, and check the control surfaces again. The ideal flying site is an unobstruc-
ted grassy field, either level or sloping gently into wind. Never launch close to
buildings or trees, as the turbulent air may make it impossible to control the
model. Switch the motor on and push the aeroplane firmly forward, directly into
wind; do not throw it! You can achieve the correct launching speed by trotting
forward a few paces. The model’s nose should be angled up slightly (approx.
15°) when launching.
Keep the aeroplane climbing gently in a straight line by applying minimal
aileron and elevator corrections. Any fine-tuning required is carried out using
the trim buttons adjacent to the sticks. The model should always be landed
with the motor switched off, heading directly into wind. Apply slight up-elevator
just before touch-down in order to reduce the model’s groundspeed.
All of us at GRAUPNER Modellbau hope you have many fine flights with your new
EXTRA 300 XS
