If the point of gravity is moved to the front, this does increase the stability, but also makes the gliding properties of the
model worse.
If the point of gravity is moved to the rear, this does improve the gliding properties, but the model becomes very
instable and it reacts extremely strongly to control commands from the elevator.
Important!
However, only experienced pilots should modify the position of the center of gravity in order to adapt
selectively the model airplane performance to their expectations and steering habits.
13. 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.
If this is not possible, look for a suitable flight terrain and wait for a day with little wind.
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. Ask an assistant to hold the model and check the range by moving slowly away from the model airplane. Up
to a distance of at least 150 m all rudder functions should be controllable even with running motors.
The transmitter antenna has to be pulled out entirely for this. The receiver antenna, which protrudes from the end of
the fuselage and is simply dragged along in flight, must not be wound up, turned over or cut off.
b) The First Start
Ask a helper to launch the electric model running at full motor performance with a gentle push against the wind.
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.
