Carson Pistol grip RC 2.4 GHz No. of channels: 3 500500037 User Manual

The transmitter technology at 2.4 GHz is fundamen-
tally different in some aspects from the technology 
in the 27,35 and 40 MHz frequency ranges, which up 
to now have been conventional with remote control 
models. The previous style of location using a 
channel determined by plug-in crystals is gone, and 
the transmitter and receiver work with encoding. 
The receiver accepts only signals with the coding 
from its own transmitter. Each signal from the 
transmitter lasts just milliseconds. Before the next 
signal, a pause is inserted, which lasts longer than 
the transmission signal. 

Nonetheless, within each second countless signals 
are received and evaluated by the receiver. Signals 
that the receiver recognizes as defective (false 
encoding, strings that don’t fit the signal schema, 
etc.) are suppressed and are not passed on as 
control commands. 

And as the frequency gets higher, the antennas get 
shorter. 

Remote controls using this transmitter technology 
or model construction are not subject to fees.

Although the frequency range used is also divided 
into channels, the user doesn’t have to worry about 
their configuration and has no influence on it 
anyway.

Because the same encoding is used by the 
transmitter  and receiver, interruption by another 
receiver or a different transmitter will not occur. 

Plug-in crystals are not needed, because the 
transmitter creates the currently appropriate 
frequency using a synthesizer circuit, as does the 
receiver, which determines the right frequency for 
ist encoding. 

The old fear of double occupancy of a channel (as 
when a second transmitter overreaches and 

interrupts a receiver) is a thing of the past. An 
operator can go ahead and switch on a transmitter 
and receiver,  without negotiating with other model 
users. 

The data transfer capacity is considerably larger 
than that of previous remote controls, which has 
a positive effect on control of the digital servo, for 
example. 

Best of all, at events with a lot of participants, you 
can always use your own equipment for settings, 
tests and conversions, because the number of 
active transmitters is almost unlimited.

At very low wavelengths, obstacles can weaken or 
interrupt the spread of radio waves. That means 
there should be as few obstacles as possible in 
the line between the transmission and reception 
antennas. 

The model’s receiver antenna must be as far away 
as possible from electrically conductive parts and 
very visibly arranged (protruding from the model) 
to prevent loss of range.
