Range Test - Pro-Tronik PTR-6A User Manual

6 RANGE TEST

2 CARACTERISTIQUES
Like any radio control system, set your Pro-Tronik requires to perform a range check before each use in the field. The
range test is intended to verify that the scope of the connection heavily dependent on the quality of the installation on
the model is ensured at all times.
A range check occurs as follows:
the model is placed and held securely to the ground in order not to be able to move
the engine must be started (gas engine) or wired (electric motor)
the pilot which normally holds the transmitter in his hands moves progressively away from the model and checks every
20 meters that he retains control normally of the control surfaces and engine slowly manipulating the sticks. When the
distance becomes large, an aide is necessary to confirm the correct response of the model (eg via a telephone link).
Under these conditions, the pilot must find an effective range, to perfectly control the model, at least 500 m. Control
must remain normal regardless of the position of the pilot in relation to the model.
If this method is the only really effective way to confirm the scope of a set of remote control, it can actually be impractical
in the field. It is indeed not easy to have such a distance in the field, and help is not always available.
This is why your Pro-Tronik set has a system for performing a range check much more simple, fast and independent.
This method, although it does not have the same reliability as the method described above, is used to evaluate reliability
with a fairly good range .
It is based on the fact that the range of a radio control depends largely on the power emitted by the transmitter (all
things together by the way).
Your transmitter is equipped with a function for temporarily reduce its transmit power to achieve a range test on a much
smaller distance, about a block away. The principle remains the same, but at this distance, you can hear variations
including engine speed, and even distinguish the moving surfaces. If the control is perfectly normal in these conditions,
you can reasonably estimate the range to be rated satisfactory. However, if the control of the model is not satisfying at
this distance or shortest distance, you should under no circumstances attempt to fly.
It is imperative to check the battery charge status antennas and quality of the radio installation. After correcting any
problems, you should make a new test range. The flight will be possible only if the range test at reduced power is valid.
Warning: this test range at reduced power does not offer the same reliability as conventional range test. It does
!
give an indication of more or less reliable range that can be expected when the power is nominal. Also, we
recommend that you perform at least once a classic range test for each new model. Testing range before each
flight will however be made at reduced power.
You will find in Chapter 7 of this manual detail to achieve a practical range test at reduced power.
