Digital Servo
A radio frequency range which is higher than previous ones such as 27MHz and 40MHz.
However, this also means it is also more direct and signal transmission may be difficult if there
are interfering objects between the transmitter and receiver.
A feature which changes the steering angle of all four wheels according to the driving
condition to enable greater stability.
A servo which uses a separate power source for its motor. In the case of electric R/C cars, KO
Propo's unique system sees the servo draw power from the 7.2V battery used for running the
car.
One of the radio frequency ranges used for the R/C hobby. 12 bands exist for both
ground-based and airborne R/C models.
One of the radio frequency ranges used for the R/C hobby. 8 bands and 5 bands are assigned
for use with ground-based and airborne R/C models respectively.
A battery charger which plugs into the standard 100V wall socket (in Japan). It often requires
charging times of several hours or more.
A buzzer sound emitted by the transmitter. It may be used as a warning notification, etc.
See ESC.
A type of servo which uses analog-type integrated circuits (IC).
Since LCDs do not generate their own light and are difficult to see in dark places, this light is
placed beneath it to illuminate the display.
Another word for radio frequency. This can be set with frequency crystals and different crystals
can dictate the frequencies used in a certain frequency range.
An item which indicates to others the frequency that a particular user is using.
The repeated action of applying and releasing the brakes.
A device which mixes air and fuel in an engine and governs engine RPM.
A trim which only adjusts the position of neutral without disturbing the overall range of travel.
Refers to the number of servos, etc. which can be controlled by a transmitter or their individual
signal numbers.
A device which is used to engage/disengage an engine's drive shaft with the transmission.
An electric circuit contact unit which can be connected/disconnected.
The core of a computer which performs digital calculations for various uses. Also sometimes
called an MPU.
A device which sets the frequency used by a transmitter. 27MHz and 40MHz systems require
crystals for changing frequencies while DSSS and FHSS 2.4GHz systems do not.
A marker on the display which indicates the position in the text which can be controlled at
that time.
A process which returns to the beginning and repeats itself.
A module containing additional memory which may be used to increase the amount of model
memory.
A battery charger which uses a 12V battery or other stable 12V power source.
Acronym for Direct Digital System. Previous transmitters transmitted an analog signal, but
transmitters such as Eurus and EX-1, which use DDS, transmit a digital signal to enable lag-free,
direct control.
An area in which transmitter wheel or trigger movement does not result in servo operation. It
could be caused by worn out components and may be resolved using VRADJ.
When an operation is slow, or has been slowed.
A type of servo which uses digital-type integrated circuits (IC).
