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.

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.
