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 as how to fly in an airplane model properly.
a) Range Test
Before the first use, the flight battery and rechargeable batteries in the transmitter (if rechargeable batteries are used) have to be charged as instructed by the
manufacturer. First perform a range test for the remote control system on 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. The transmitter aerial must be completely collapsed with 35/40 MHz remote controls,
and the receiver aerial, which protrudes from the end of the fuselage and is simply dragged along in flight (with 35/40 MHz remote controls), must not be wound
up, turned over or cut off.
b) 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 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 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.
Being familiar with this borderline situation 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.
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.
d) The First Landing
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.
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.
