12. Flying the model
After having checked the functioning of the motor as well as the direction of the rudder surface travel, your model is
ready for its first flight. However, we recommend you contact an experienced model airplane pilot or a model construc-
tion club in your area if you are not sure as how to fly an airplane model.
If this is not possible, look for a suitable flight terrain and wait for a day with little wind.
a) Testing the Range
Before the first start-up, you should charge the flight battery and an eventually inserted transmitter-rechargeable bat-
tery according to the specifications of the manufacturer.
First carry out a range test of the remote control on the flying site. Put the transmitter into operation first 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 150 m all rudder functions should be controllable even with running motors.
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.
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 rise up quickly at a flat angle. Do not attempt to steer
it more than necessary.
It is only when the model modifies the flight attitude automatically and e.g. flies a curve, rises too high or wants to
plunge, that you can start correcting the flight attitude via the necessary steering commands.
For a sensitive correction of the flight attitude and for selective direction modifications of the normal flight attitude, only
few or momentary control stick movements at the transmitter are necessary.
c) Spiralling
Spiralling is initiated with the fin unit; the model angles to the side. If the model has reached the desired declination,
the rudder is put back into centre position. Now, the curve can be flown at a constant altitude by gently pulling the
elevator control stick.
When the model flies in the desired direction, a quick regulation of the rudder into the opposite direction will bring the
model back to a horizontal position and also return the elevator to the centre position.
If the model starts to sink in the curve, you did not pull the elevator control stick strongly enough. If the model starts to
rise in the curve, you pulled the elevator control stick too strongly.
If the curve is very generous, the fin rudder was not deflected enough or long enough. If the curve is very tight and the
model is extremely slanted, the fin rudder was operated too long or too strongly.
