Flying the Model In
Having checked the centre of gravity, the motor function and the direction of the deflections, 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 how to fly in an airplane model properly.
a) Range Test
Before the first take-off, the inserted batteries (e.g. transmitter, receiver, flight battery) must be charged according to
manufacturer information. First perform a range test for the remote control system in the flight area. Switch on the
remote control and then the receiver. Now check the range according to the notes in the operating instructions of your
remote control.
b) The First Start
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.
When flying, always observe sufficient flight speed. 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 try out the model's „stalling behaviour" repeatedly at a sufficient safety
altitude – with head wind as well as with tail wind – by reducing the speed (reduce motor speed) and „maintaining the
altitude". Being familiar with this borderline situation is of value when choosing the required landing speed.
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 in flight.
Always find the reason for which trimming was required after touch-down, and correct it (e.g. motor inclination, etc.).
For this, measure your model (e.g. wing angle, motor traction, etc.) again and correct the settings according to the
measurements.
d) The First Touch-Down
The first flight should not extend over a long period of time. Try to land the model after a little while. This gives you
enough time to make several landing attempts without exhausting the battery.
Like the first flight, the first landing should always be done 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 the landing approach so that you have sufficient room for landing and the course does not
have to be changed significantly when 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.
