IMPORTANT
:
Since the 2.4GHz have different characteristics than that of the conventional 27MHz and 72MHz
frequencies, please read this addendum carefully to enjoy safe flight with the 2.4GHz system.
[Receiver's Antenna Installation]
• The R617FS has two antennas. These antennas
have a diversity function to decrease the chance of a
receiving error.
• Since the wavelength of the 2.4GHz is much shorter
than that of the conventional frequencies 27MHz
and 72MHz, it is very susceptible to loss of signal
which results in a receiving error. In order to avoid this
phenomenon, the R617FS adopted a diversity antenna
system.
• To obtain the best results of the diversity function,
please refer to the following instructions;
1. The two antennas must be kept as straight as
possible. Otherwise it will reduce the effective range.
2. The two antennas should be placed at 90 degrees to
each other.
This is not a critical figure, but the most important thing
is to keep the antennas away from each other as much
as possible.
Larger models can have large metal objects that can
attenuate the RF signal.In this case the antennas
should be placed at both sides of the model. Then
the best RF signal condition is obtained at any flying
attitude.
3. The antennas 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.
If the fuselage is made of conductive materials such as
metal and carbon, the antennas part MUST be placed
at outside of the fuselage. In addition, do not attach
the antenna part on the fuselage. For example, there
are many types of gliders which use carbon fuselage.
When install the receiver into that kind of fuselage, this
guideline must be kept.
4. Keep the antennas away from the motor, ESC, and
other noise sources as much as possible.
5. Be very careful when handling the receiver
antennas. Repeated motion in or out of the case holes
or excessive pulling force could break or compromise
the internal antenna connections.

R617FS
7 channel receiver of FASST system
Futaba R617FS 7 channel receiver of FASST system is packed in this set.
*The two antennas should be placed at 90 degrees to each other.
*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.
