Once the model is properly trimmed, you can practise the
art of flying, and carry out manoeuvres such as circles,
squares, rectangles and figures-of-eight.
To avoid giving incorrect control commands, always stand
behind and to one side of the model.
You can fly a square pattern by alternating the direction
of flight: away from the pilot, to the pilot's right, and then
towards the pilot.
Tip: when the model is flying with the nose pointing
towards you, the controls are reversed (apart from
elevator and throttle control).
Important Notes
Launching: Hold the model in your hand, set the motor to full power, and
push the model forward smartly, directly into any wind. It is essential to
adjust the trims so that the aeroplane flies in a stable attitude, climbing
smoothly. Use the controls gently at first to learn how the model responds
to flight commands.
Landing: Slowly and steadily reduce the throttle setting until the mo-
del descends and touches down. The ailerons can be used as airbrakes
using the left switch on the transmitter; this helps to reduce wing lift; at
the same time the aileron function is still available. Once the model has
landed, disconnect the flight battery from the receiver, and finally switch
the transmitter off.
Caution: Stopping (obstructing) the motor when it is turning can cause
serious damage to the mechanical system, and may even result in a fire.
If the propeller is forcibly stopped, immediately move the throttle stick
back to Idle!
Note re. the flight battery: As soon as you notice a reduction in motor
power, land immediately and disconnect the battery. Never continue
flying until the battery is flat, as this causes a deep-discharge condition,
which results in permanent damage. Allow the battery to cool down
before recharging it.
Replacing the propeller:
A damaged propeller must be replaced immediately.
