Notes on Receiver Usage
The Source of Noise and Electromagnetic Induction
(Electric-powered car)
Assume that all areas where large currents are flowing are generating noise!
Locate antenna wires and receivers as far away from the motor, ESC, nicad
batteries,and silicone wire as possible. Noise is a type of radio wave, and
therefore is radiated (travel through the air) in the same fashion. Therefore,
locating an antenna near a noise source increases the effect of the noise.
Distance Between the Receiver and Antenna Holder
Install the antenna holder as near to the receiver as possible.
The easier it is for the antenna to pick up noise,the sensitivity
of the receiver will decrease.
Metals and carbon can also conduct noise.
As a result, you should never
closely attach the antenna wire to the plate
and carbon chassis.
Because this is also
part of the antenna,
it is easier to pick up
nearby noise.
