12. Flying the model
After having checked the center of gravity, the functioning of the motor as well as the direction of the rudder travel, your model is ready for its first flight. However,
we recommend you contact an experienced model airplane pilot or a model construction club in your area if you are not sure as how to fly an airplane model.
If this is not possible, seek out a suitable flight area and wait for a day with little wind.
a) Testing the Range
Before the first start-up, you should charge the flight battery and any transmitter rechargeable battery you may have inserted according to the specifications of
the manufacturer. First carry out a range test of the remote control in the flight area. Put the transmitter into operation first and then the receiver. Ask an assistant
to hold the model and check the range by moving slowly away from the model airplane. Up to a distance of at least 100 m all rudder functions should be fully
controllable even with the motor running. The transmitter antenna must be extended all the way, and the receiver antenna, which protrudes from the end of the
fuselage, must not be wound up, turned over or cut off.
b) The First Start
If no hard runway is available for starting from the ground, ask an assistant to launch the electric model in a straight line forward or slightly upward against the
wind with a gentle push at full motor speed. Practice has shown that it is best if the assistant holds the model with one hand in the middle of the upper wings and
with the other hand on the side fin unit.
Our tip:
In order to be able to identify the flight attitude of your model, you should stand at a little distance behind your assistant and look exactly in the flying
direction of the launched model.
If the assembly was carried out correctly, then the model should climb quickly at a flat angle. Do not attempt to steer it more than necessary. Only when the model
modifies the flight attitude automatically and e.g. flies a curve, climbs too high or wants to plunge, that you can start correcting the flight attitude using the
necessary steering commands. Only minimal or momentary control stick movements at the transmitter are necessary to achieve precise correction of the flight
attitude and for selective direction modifications of the normal flight attitude.
Warning!
When flying always ensure a sufficient flying speed. Pulling too hard on the elevator rudder control stick may cause the model to become too slow
and it may tilt forwards or sideways over one wing.
Therefore, ensure at the beginning that you fly at a sufficient safety height in order to allow yourself to get used to the steering attitude of the model. Do not try
to fly too far in order to be able to clearly evaluate (see), at any time, the flight attitude.
c) Trimming the Model
If in straight flight your model shows a tendency to drift in one direction, correct the neutral position of the corresponding rudder using the trim.
Aileron:
If the model "drags" the left wing, push the trim lever (fig. 2, Pos. 5) step by step towards the right until the model flies with both wings at the same level in a
straight line. If the model "drags" the right wing, carry out a trim correction towards the left.
Rudder:
If the model drifts towards the left, push the trim lever (fig. 2, Pos. 9) step by step towards the right until the model flies in a straight line. If the model drifts towards
the right, effect a trim correction towards the left.
Elevator:
Set the trim lever for the elevator (fig. 2, Pos. 3) in such a way that at full motor speed the model rises in a flat angle and that at reduced motor speed it flies at
a constant altitude.
