12. Flying the Model In
After checking the centre of gravity, the motor functions and the rudder surface travel directions, your model is ready for its first flight. We recommend contacting
an experienced model plane pilot or a model making club in your area if you are not familiar with flying in model planes.
If this is not possible, look for a suitable flight terrain and wait for a day with little wind.
a) Range Check
Before the first start-up, you should charge the flight battery and any possibly inserted rechargeable batteries in the transmitter according to the specifications of
the manufacturer. First carry out a range check of the remote control on the flying site. For this, switch on the transmitter first, then the receiver. Press the "PDM"
button (see fig. 2, item 8) at your transmitter for more than 3 seconds; the green LED goes out. This decreases transmitter output. Now check the range by having
someone assist you by securely holding the model, and walk away from the model slowly. Up to a distance of at least 15 m, all rudder functions should be
controllable even with decreased transmitter output. The decreased transmitter output will revert again automatically after 60 seconds. To end this mode earlier,
press the "PDM" button again.
Important!
Never start your flight while the transmitter output is still decreased. This may cause the model to crash.
b) The First Flight
Ask a helper to launch the electric model running at full motor output against the wind with a gentle push. Ensure that the assistant's fingers do not reach into the
propellers when he launches the plane.
Our advice:
In order to be able to distinctly see the flight attitude of your model, you should stand at a short distance behind the person assisting you and look
into the flight direction of the starting model.
If the assembly was carried out correctly, the model should rise up quickly at a flat angle. Try to control the model as little as possible. Only steer the model if it
changes its flight attitude by itself and e.g. flies a curve, ascends too high or is about to nose-dive. To sensitively correct the flight attitude and to carry out specific
changes of direction in normal flight attitude, short and limited movements of the control stick on the transmitter are sufficient.
Attention!
Always make sure the model plane flies at sufficient speed. Pulling the elevator control stick too far causes the model to slow down. It can turn over
laterally.
Therefore, fly at a sufficient safety height in the beginning in order to allow yourself to get used to the steering attitude of the model. To ensure a problem-free first
landing, first practice repeatedly at a sufficient safety altitude - with head wind as well as with tail wind - reducing the speed (reduce motor speed) and at the
same time maintaining the altitude or stalling.
Stall behaviour is an uncontrollable flying condition due to insufficient airflow which causes the plane to tilt to the side uncontrollably. The stall is the minimum
flight speed (with head wind or tail wind) at which the model can still be controlled because the airflow at the wings is still sufficient.
Determining this borderline situation in flight is of value when choosing the landing speed. Do not try to fly too far in order to be able to clearly evaluate, at any
time, the flight attitude.
c) Trimming the Model
If your model tends to drift to one direction in straight flight, correct the neutral position of the corresponding rudder by trimming.
Aileron:
If the left wing of the model "hangs down", gradually push the trim lever (see figure 2, item 5) to the right until both wings are in line when the model is flying
straight ahead. If the right wing of the model "hangs down", carry out the trim correction to the left.
Elevator:
Set the trim lever for the elevator (see figure 2, Item 3) in such a way that the model rises in a flat angle at full motor speed and that it flies at a constant altitude
at a reduced motor speed.
After landing, you may re-adjust the aileron and the elevator linkage so that the model flies straight and the trim levers on the transmitter are in centre position
again.
Rudder:
If the model drifts towards the left, push the trim lever (see figure 2, Item 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.
