R617FS

7 channel receiver of FASST system

Futaba R617FS 7 channel receiver of FASST system is packed in this set.
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.

Coaxial cable*Must be kept as straight as possible.

R617FS Receiver[Receiver's Antenna Installation]• The R617FS has two antennas. These antennas
have a diversity function to decrease the chance of areceiving 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 thisphenomenon, the R617FS adopted a diversity antennasystem.
• To obtain the best results of the diversity function,please refer to the following instructions;
1. The two antennas must be kept as straight aspossible. Otherwise it will reduce the effective range.
2. The two antennas should be placed at 90 degrees toeach other.

• Dual antenna diversity• Power requirement: 4.8V or 6.0V battery or regulated
output from ESC, etc. (*1)
• F/S and Battery F/S function for throttle channel (channel three)• Size: 1.64 x 1.08 x 0.36 (41.6 x 27.5 x 9.2 mm)• Weight: 0.34 oz (9.8 g)(*1)
Be sure that when using ESC's regulated output thecapacity of the ESC must meet your usage condition.
(Speciﬁcations are subject to change without prior notice.)This is not a critical ﬁgure, but the most important thingis to keep the antennas away from each other as muchas possible.
Larger models can have large metal objects that canattenuate the RF signal.In this case the antennas
should be placed at both sides of the model. Thenthe 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 halfinch. 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 placedat 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, thisguideline must be kept.
4. Keep the antennas away from the motor, ESC, andother noise sources as much as possible.
5. Be ver y careful when handling the receiverantennas. Repeated motion in or out of the case holes
or excessive pulling force could break or compromise
the internal antenna connections.
