welcome nagarajan
you can get a pure
simulator box like this oneHow i use same simulator controller for flying an aeroplane/heli
or buy a transmitter and a
dongle(USB) like this one ,
use the transmitter (Like this) to fly the model virtually using the dongle or in real using the receiver supplied with a transmitter like the one shown below
they both visually may look the same, however pure trainer box does not have a transmitting module and a it doesn't come with a receiver for obvious reasons
