Special note for 2.4GHz FHSS radio system setup
Since the 2.4GHz have different characteristics than that of the conventional
frequencies, please read this section carefully to enjoy safe flight with the
2.4GHz system.
Receiver’s Antenna installation
The R601FS has two antennas. These antennas have a diversity function to
decrease the chance of a receiving error.
The wavelength 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. In order to avoid this phenomenon, the R601FS 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.
4. Keep the antennas away from the motor, ESC, and other noise sources as much
as possible.
* 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.
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.
Transmitter antenna
1. The transmitter antenna is adjustable
so please make sure that the antenna is
never pointed directly at the model
when flying as this creates a weak signal
for the receiver.
2. Keep the antenna perpendicular to the
transmitter's face to create a better RF
condition for the receiver. Of course
this depends on how you hold the
transmitter, but in most cases, adjusting
the transmitter antenna so that it is perpendicular to the face will give the
best results. Please adjust the transmitter antenna to the way you hold the
transmitter.
3. NEVER grip the antenna when flying as this degrades RF quality.
Pair Procedure
The transmitter has a individual randomize ID that is created in the factory,
In order to start operation, the receiver must be linked with the ID code of
the transmitter with which it is being paired. Once the link is made, the ID
code is stored in the receiver and no further linking is necessary unless the
receiver is to be used with another transmitter. When you purchased another
R601FS, this procedure is necessary; otherwise the receiver will not work.
1. Place the transmitter and the receiver close to each other within 1 meter.
2. Turn on the transmitter then the receiver. If they are not paired, the receiver
red LED will blink per second or off, follow the next steps to link and pair
the receiver and the transmitter:
3. Press down the receiver "pair button" switch for more than two seconds,
once the receiver LED start to blink quickly, it shows they are paired,
release the switch.
4. When the linking is complete, the receiver LED will change to solid red
and receiver will start to response to the transmitter after 2 seconds. Please
refer to the table below for the LED status of the receiver's condition.
Receiving signals and ID is matched. : On
Receiving signals, but ID is matched. : Off
No signal reception. : Off
Receiver ID memory is empty. : Blink per second
Change the transmitter ID
The transmitter has a individual randomize ID that is created in the factory,
Even it is almost have no chance to meet the same ID transmitter in the same
fly field, in case it does happen. The transmitter has an ID set up function.
By holding the “PDM” button to turn on the transmitter, the two LED will
blink. Press the “PDM” bottom to random change a new ID, the new ID will
active when the transmitter turn on next time, Once you have set up a new ID
for your transmitter, please must remember to re-Link your receiver with
your transmitter before flight.
You can go back to the original factory set ID by holding the “PDM” when
turn on the transmitter, without press the “PDM” bottom, turn it off and on
again to get back the original ID.
Range check the radio
A range check must be performed before the first flight of a new model. It is
not necessary to do a range check before every flight (but is not a bad idea to
perform a range check before the first flight of each day). A range check is
the final opportunity to reveal any radio malfunctions, and to be certain the
system has adequate operational range.
1. There is "Power Down Mode" build in for doing a ground range check
To activate the "Power Down Mode" by pressing the “PDM” button
on the right upper panel of the transmitter. The Green LED will turn
off to indicate the PDM is working. During this mode, the RF power is
reduced so the range test can be performed.
2. Walk away from the model while simultaneously operating the controls.
Have an assistant stand by the model and signal what the controls are
doing to confirm that they operate correctly. You should be able to walk
30 - 50 paces approximately from the model without losing control.
3. If everything operates correctly, return to the model. The "Power Down
Mode" continues for 60 seconds and after that the power will go back to
the normal level. To exit the "Power Down Mode" before the 60 seconds,
press the "PDM" key again.
4. NEVER start flying when the "Power Down Mode" is active.
Transmitter Operation and Movement of Each Servo
Before making any adjustments, learn the operation of the transmitter and the
movement of each servo. (In the following descriptions, the transmitter is assumed
to be in the standby state.)
AILERON OPERATION
When the aileron stick is moved to the
right, the right aileron is raised and the left
aileron is lowered, relative to the direction
of flight, and the plane turns to the right.
Aileron(ch1)
(Viewed from the rear)
Left
When the aileron stick is moved to the left,
the ailerons move in the opposite direction.
To level the plane, the aileron stick must
be moved in the opposite direction.
When the aileron stick is tilted and held,
the plane will roll.
ELEVATOR OPERATION
Left Right Right
When the elevator stick is pulled back, the
tail elevator is raised and the tail of the
plane is forced down, the air flow applied
to the wings is changed, the lifting force is
increased, and the plane climbs (UP opera-
tion). When the elevator stick is pushed
forward, the elevator is lowered, the tail of
the plane is forced up, the air flow applied
to the wings is changed, the lifting force is
decreased, and the plane dives (DOWN
operation).

WARNING
Connector Connection
Insert the receiver, servo, and
battery connectors fully and
firmly.
If vibration, etc. causes a connector to
work loose during flight, the plane may
crash.
Receiver Vibrationproofing
/ Waterproofing
Vibrationproof the receiver by
wrapping it in sponge rubber or
some such material. If the re-
ceiver may get wet, waterproof
it by placing it in a plastic bag.
If the receiver is subjected to strong vibra-
tion and shock, or gets wet, it may operate
erroneously and cause a crash.
Receiver Antenna
Do not cut or bundle the re-
ceiver antenna. Also, do not
bundle the antenna together
with the servo lead wires.
Cutting or bundling the receiver antenna
will lower the receiver sensitivity and
shorten the flight range and cause a crash.
<Antenna installation>
For aircraft, attach the antenna to the top of
the tail.
Servo Throw
Operate each servo horn over
its full stroke and adjust so that
the pushrod does not bind or is
not too loose.
Unreasonable force applied to the servo
horn will adversely affect the servo and
drain the battery quickly.
Servo Installation
Install the servos to the servo
mount, etc. through a rubber
grommet. Also install the servos
so that the servo case does not
directly touch the servo mount
or other parts of the fuselage.
Power Switch Installation
When installing a receiver power switch to the
fuselage, cut a rectangular hole somewhat
larger than the full stroke of the switch knob
and install the switch so it moves smoothly
from ON to OFF.
Also install the switch where it will not come
into direct contact with engine oil, dust, etc.
Generally, install the switch to the fuselage at
the side opposite the muffler exhaust.
Adjustments
The operating direction, neutral position, and steering angle of each servo are adjusted.
CAUTION
The basic linkage and adjustments of the fuselage conform to the fuse-
lage design drawings and kit instruction manual. Be sure that the center
of gravity is at the prescribed position.
Adjustment Procedure
Before making any adjustments, set
all the SERVO REVERSER switches
on the front of the transmitter to the
lower (NOR) position. (Switch the
switches with a small screwdriver, etc.). If the neutral position has changed, reset
etc.)
Turn on the transmitter and receiver
power switches and make the follow-
ing adjustments:
1 Check the direction of opera-
tion of each servo.
If a servo operates in the wrong direction,
switch its SERVO REVERSER switch. (The
direction of operation can be changed without
changing the linkage.)
*Note that the direction of the aileron servo is
easily mistaken. (Page 10)
2 Check the aileron, elevator,
and rudder neutral adjustment
and left-right (up-down) throw.
Check that when trimmed to the center, the
servo horn is perpendicular to the servo and
check the neutral position of the fuselage
control surfaces (aileron, elevator, rudder,
it by adjusting the length of the rod with the
linkage rod adjuster.
When the throw is unsuitable (different from
steering angle specified by the kit instruction
manual), adjust it by changing the servo horn
and each control surface horn rod .
3 Check the engine throttle
(speed adjustment) linkage.
Change the servo horn installation position
and hole position so that the throttle is opened
fully when the throttle stick is set to HIGH
(forward) and is closed fully when the throttle
stick and throttle trim are set for maximum
slow (backward position and lower position,
respectively).
4 After all the linkages have
been connected, recheck the
operating direction, throw, etc.
*Before flight, adjust the aircraft in accor-
dance with the kit and engine instruction
manuals.
5 Fly the plane and trim each
servo.
