10. Flying the model
After having checked the center of gravity, 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 construction club in your area if you are not sure as how to fly an airplane
model properly.
a) Testing the Range
Before the first start-up, you should charge the flight battery and an eventually inserted transmitter-rechargeable battery 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. Now check the range in
accordance with the instructions in the operating manual of your remote control. The transmitter antenna must be completely collapsed with 35/40MHz remote
controls, and the receiver antenna, which protrudes from the end of the fuselage and is simply dragged along in flight (with 35/40MHz remote controls), must not
be wound up, turned over or cut off.
b) The first start
Ask someone to help you with the first start by holding the model on the rear at the rudder unit and first releasing the model against the wind once the motor
operates at full 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 assembled correctly, the model will rise quickly at a flat angle after a short roll phase and a brief deflection of the elevator. 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.
Attention!
When flying always ensure a sufficient flying speed. Pulling too hard at the control stick of the elevator causes the model to slow down; it can
turnover laterally over a wing.
Therefore, ensure at the beginning a sufficient safety height 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.
Stalling is an uncontrollable flight status caused by insufficient airflow, which causes the model to tilt sideways across one wing. Stalling is therefore the lowest
flight speed (with and against the wind) at which the model can still be controlled due to sufficient air flow on the wings.
Defining this speed is vital for later landing operations to select the correct 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 in straight flight your model shows the tendency to drift to one direction, correct the neutral position of the corresponding rudder via the trimming.
Fly some rounds at a safe height to get used to the steering behaviour of your model airplane.
Attention!
Due to its compact design, your should not let the model fly away too far and also observe a sufficient flight speed at the same time.
d) The first landing
Do not prolong 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 accumulator capacity.
You should always start and land against the wind. Reduce the motor performance and fly in big flat circles. Do not pull too hard on the elevator in order to be able
to reduce the flying altitude selectively.
Select the last curve before the approach 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 effect considerable corrections to the course during the approach for a landing. When the model is flying on the planned landing line, reduce the motor
performance further or shut the motor off altogether and hold it horizontally with the elevator. Now the model must loose height further and must fly towards the
planned touch-down point at the end of the imaginary landing line.
