Special notefor 2.4GHz FHSS radio system setup
Receiver ’s Antenna installation
Since the 2.4GHz have different characteristics than that of the conventional frequencies,
please read this section carefully to enjoy safe
fl
ight with the 2.4GHz system.
The wave length of the 2.4GHz is much shorter than that of the conventional frequencies,
it is very susceptible to loss of signal which results in a receiving error.
To obtain the best results, please refer to the following instructions;
1. The antenna must be kept as straight as possible.
Otherwise it will reduce the effective range.
2. The antenna should be perpendicular to the fuselage.
Larger models can have large metal objects that can
attenuate the RF signal. In this case the antenna should
be placed at side of the model. Then the best RF
signal condition is obtained at any flying attitude.
3. The antenna must be kept away from conductive materials, such as metal and
carbon by at least a half inch. The coaxial part of the antennas does not need to
follow these guidelines, but do not bend it in a small radius.
4. Keep the antenna away from the motor, ESC, and other noise sources as much
as possible.
* The main purpose of the photo
demonstrates how the antenna should
be placed. For actual installation the
receiver must be wrapped with a
sponge or placed with floating material
to protect it from vibration.

The receiver contains precision electronic parts. It is the most delicate radio
component on-board the model and should be protected from vibration,
shock and temperature extremes. To protect the receiver, wrap it in R/C foam
rubber or other vibration-absorbing material. If appropriate, waterproof the
receiver by placing it in a plastic bag and closing the open end with a rubber
band before wrapping it in foam. If moisture enters the receiver, intermittent
operation or a failure may result. Wrapping the receiver in a plastic bag also
protects it from fuel and exhaust residue which, in some models, can work its
way into the fuselage.
