10. 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. After touch-down, always
find the reason for which trimming was required, and correct it (e.g. motor inclination, etc.). For this, measure your model (e.g. wing angle, motor traction, etc.)
again and correct 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 (or the fuel).
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.
In this critical flying phase, ensure sufficient flying speed and do not slow down the model 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 – if necessary – so that the plane flies straight and the trim levers on the transmitter are in centre position again. Once you are
able to control the airplane perfectly, you can try to optimise flight performance by shifting the centre of gravity.
