10. 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. If you do not have sufficient
flight experience, we recommend that you always contact an experienced model flight pilot for your initial flight.
a) The First Start
For the first flight, have someone assist you by holding the electric model at the rear of the rudder unit and releasing the model against the wind only when the
motor is working at full power.
Our tip:
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 ascend speedily at a flat angle after a short rolling phase and a short deflection of the elevator. Try
to steer 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!
When flying, always observe sufficient flight 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.
A stall is an uncontrollable flying condition due to insufficient airflow which causes the plane to tilt to the side. 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.
b) 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.
Fly some rounds at a safe height to get used to the steering characteristics of the model.
Attention!
Due to its compact design, you should not let the model fly away too far and also make sure it flies at sufficient speed.
c) The First Touch-Down
Do not make your first flight too long and try to land your model airplane again as soon as possible. This gives you enough time to perform several landing
operations without exhausting the rechargeable battery capacity.
You should always start and land against the wind. Reduce the motor speed and fly in wide and flat circles. Do not pull on the elevator too hard to reduce the
flying altitude slowly.
Select the last curve before approaching for a landing so that, in case of an emergency, you would have sufficient room for landing and so that you would not
have to make any considerable corrections to the course during the approach for a landing. When the model is flying along the planned landing line, reduce the
motor speed further or turn off the motor completely, and keep the model in a horizontal position using the elevator. The model now should lose height and fly
towards the planned touch-down point at the end of the imagined landing line.
In this critical flying stage, ensure sufficient flying speed (see chapter "First start – stalling behaviour") and do not slow down the model while reducing the motor
speed too much or by pulling too hard at the elevator.
Slightly move the elevator briefly before touchdown.
After landing, adjust the linkage rods so that the airplane flies straight and ensure that the trim levers on the transmitter are in the central position again. When
you use a state-of-the-art computer remote control, you can correct small deviations in the transmitter. Larger deviations should be set mechanically approximately
first and then finely with the electronics. Once you are able to handle the airplane perfectly, you can try to optimise its flight by shifting the balance point.
