Radio system for Toys

The radio system is to connect between you and your model rc
toys (remote control toys) such as rc car, rc helicopter, nitro
rc car, rc gas boat, remote control helicopter, remote control
car etc.. It looks like a bit complicated at the very beginning
but with some study, all aspects of the radio system can be
easily understood. We will introduce you to the radio system
here and explain a few of the features found on many of the
systems available today.

Radios are separated into two groups, those used for model
aircraft and those used for surface models. Although the
operation, electronics, and mechanics for both types of systems
are virtually identical, they operate on different sets of
frequencies. The separation is stipulated by law and it is to
protect the safety of the modeler and those in the vicinity. A
flying aircraft can be dangerous if it becomes uncontrolled and
the frequency separation helps avoid an aircraft being
interfered with by someone operating a car or boat. In addition
to a difference in frequencies, some surface radios are also
available as a pistol grip control which is ergonomically easier
when controlling cars and boats. A pistol grip for aircraft
would be impractical. The first criteria one usually looks for
when choosing a radio is the number of control functions or
channels. (Note that the term channels here refers to the number
of controls and does not have anything to do with the frequency
on which the radio operates.) Generally modern radio systems are
available with anything from 2 to 10 channels.

What comes with the radio Transmitter: The transmitter is the
control box which you hold that converts your human control
movements into electrical impulses and sends them via radio
waves to the receiver in your model. Receiver: The receiver is
the small electronic unit in your model which converts the radio
signal from your transmitter into electrical control signals
which can be sent to your servos. Servos: Servos are the devices
in the model which actually produce the control movements. They
convert the electrical signals from your receiver into physical
movement to control your model. A different servo is required
for each control function or radio channel. Batteries: Virtually
all 4-channel and greater systems come complete with
rechargeable NiCd battery packs for both receiver and
transmitter. Dual Charger: A dual charger will come with any
system that is complete with NiCd batteries. It will charge both
the receiver pack and the transmitter pack at the same time.
Switch Harness: A switch harness is provided to turn off the
power to the receiver and servos in the model. It goes between
the battery pack and receiver and also has a lead for charging.
Servo Accessories: Most radio systems will come with additional
servo arms and hardware for mounting them. P.S. Common rc toys
(remote control toys) and hobby items: rc car, rc helicopter,
nitro rc car, rc gas boat, remote control helicopter, remote
control car etc.
