video transmission equipment, we still strongly recommend that the users in such kind of
need perform the range check in the field before each operation of the radio control model.
c. The transmission mode of the 2.4GHz band RF signal is similar to a straight line, so
the buildings or tall trees could greatly obstruct the 2.4GHz RF signal. When using the X8
2.4GHz radio control system, make sure the controlled model is within visual range and
angle, i.e. there is no obstruction between the controlled model and the transmitter, and the
antenna of the transmitter should be directed to the model. During the indoor operation,
walls will easily block 2.4GHz signal, so please make sure that the transmitter and the
controlled model are in the same room.
4.3 Safety measures
When the model controlled by X8 2.4GHz radio control system is on margin of the
maximum distance of control, the reaction of the model will slow down. It is a of the safety
measures designed by ASSAN. Therefore, when the user feels that the reaction of the
model gets slower, please get the model closer right away.
4.4 Measures after signal loss
In some special circumstances, the signal could be lost. X8 2.4GHz system has a safer
and more intelligent measure to deal with signal loss.
When the signal loss occurs, the receiver will automatically start up the signal loss
protection procedure: each of the control surfaces will be recovered to the neutral position,
i.e. when the signal is loss, all the control surfaces will get back to the initial position as when
the equipment is just turned on.
Usually in that moment, each of the control surfaces will be at the neutral position and
the accelerator will be in low run (the fuel-driven model will be in idle speed while the
electro-model will be in shutoff status).
This is the safest measure for signal loss protection. If you have special requirement for
the control surface, please preset the position of the joysticks at where you want when
turning on the equipment.
*The signal loss protection mode of V2 series receivers can be set by computer. Please
refer to the setting instructions for V2 series receivers for details.
4.5 Power supply capacity
X8 series receiver requires a voltage higher than 3.6V.
In the case of multiple servos or digital servos, the user should take the large current
consumption in consideration as they might greatly lower the voltage of the system power
supply. Therefore, the power supply capacity of the battery, the power supply capacity of the
BEC carried by electric tuning panel or the separate BEC as well as the consumption
demand of the servos should be taken into full consideration.
Generally, the nominal power supply capacity differs from the capacity in actual use.
The instantaneous shortage of the voltage will cause the X8 2.4GHz radio control system to
lose its binding status and make it out of control.
To guarantee the safety of use, please make sure that the power supply capacity of the
battery has certain surplus.
4.6 Setting of gyroscope
When applying X8 2.4GHz system to helicopter model, pay attention that the X8
2.4GHz system might be different from the gyroscope in the original transmitting and
receiving system in terms of neutral position and sensitivity settings.
The user needs to make some necessary adjustment on the setting of the gyroscope
