Antenna
The strong radio wave radiate from the side of the transmitter antenna. Do not point
the antenna directly toward the aircraft during flight.
LED indicators
There are four LED indicators, which are used to display the current status and
battery level of the transmitter.
Power Switch
It is used to turn on/off the power of the transmitter.
Neck Strap Attachment
For a long flight you can choose to use a neck strap for easy handing. The neck
strap attachment is on the neutral position, in order to get the best balance for
transmitter.
Switch
CH5: 2 positions, alternate, short lever
CH6: 3 positions, alternate, short lever
Sticks
The positions of the sticks on MODE 1 and MODE 2 are shown in the figure above.
Digital Trims
GAVIN-6A features four digital trims. Each time you press a trim button, the servo
output will move one step and a tone will emit. If you press and hold it, the output will
scroll in that direction until the trim button is released or the output reaches its ends.
In additon, when the trim position returns to the center, the tone will change and the
output will pause a second.
CAUTION
: The trim positions you have set will be stored in memory and will
remain there even the transmitter powered off.
Simulator port
Connect the transmitter and the computer with a simulator converter, and then
perform a simulating flight on computer. In order to activate this function, you need to
purchase an optional simulator converter (with a dongle) and install the flight
simulator software on the computer.
Receiver Connections
The channels of DETRUM RXC7 receiver are labeled with names, as shown in the
following figure.
When connecting the servo to the port on receiver, please note the line sequence. For
each channel, signal wires are close to the top of the receiver, middle is VDD and
bottom is GND.
If the ports become detached while flying, there will be a risk of uncontrolled
operation. Please securely insert all of the connectors as far as they will go.
The two antennas of the receiver should be placed at 90 degrees to each other. Do
not place the two antennas twisted together or in parallel.
Functions and Operations
Installing the Transmitter Batteries
The GAVIN-6A requires four heavy-duty or alkaline AA batteries.
Remove the battery cover and install four AA batteries according to the polarity mark in
the battery box. Replace the battery cover.
Note
: NiCd or NiMH rechargeable AA batteries can also be used.
Low Battery Alarm
In normal operation, the LED indicators located at the upper front of the transmitter
show the current battery level.
For details about the LED indicators status, please see the table below.

: LED is on.
: LED is off.
: LED is slow flashing.
: LED is fast flashing.
When the battery level is low, the transmitter will alarm.
Low Battery Alarm: When the battery level drops below 10%, a slow alarm will sound
and LED1 will start slow flashing.
Critical Low Battery Alarm: When the battery level drops below 5%, a fast alarm will
sound and LED1 will start fast flashing.
CAUTION
: When the battery is low, please return immediately, to avoid loss of
control or crash.
Binding
In order for the transmitter and receiver to communicate, it is essential to pair or bind
them together. When you use the R/C system first time or change a transmitter/receiver,
this procedure is necessary. Each transmitter has an individually assigned, unique ID
code. Once the binding is made, the ID code is stored in the receiver and no further
binding is necessary after restarting the receiver.
Preconditions:
Move the throttle stick to the lowest position and make sure the transmitter is
powered off.
Place the transmitter and the receiver close to each other within a distance of about
one meter.
Steps:
1. Insert the bind plug into the
BIND
port of the receiver.
2. Power on the receiver. The LED on the receiver will start red slow flashing, indicating
that the receiver is in bind mode and ready to be bound to the transmitter.
3. Turn on the power switch of the transmitter, the system begins to bind.
4. Once the LED on the receiver stays green, indicating the receiver is bound to the
transmitter.
5. Turn off the transmitter and receiver. Remove the bind plug from the receiver.
Calibrating the sticks
This function calibrates the neutral position and travel of the sticks. Stick calibration is
required in the following conditions:
Use the transmitter first time.
The positions of the sticks are inconsistent with the expected results.
Preconditions:
Move the throttle stick to the lowest position and make sure the transmitter is
powered off.
Steps:
1. Right press and hold the digital trim below the right-hand stick, while turning on the
power switch, the transmitter will enter stick calibration mode.
On stick calibration mode, the four LED indicators will flash green in sequence.
2. Move both right and left sticks up and down and right to left, next set both right and
left sticks to their center position.
3. Left press the digital trim below the right-hand stick to confirm the calibration.
If the LED indicators display constant green, it means the calibration is successful.
If the LED indicators still flash green in sequence, it means the calibration is failed,
please retry.
HI/LO Rate
The GAVIN-6A offers a dual (high/low) rate function on aileron, elevator, and rudder. The
HI/LO rate switch are located at the lower front of the transmitter and are used to switch
aileron, elevator, and rudder control surfaces. Status of the switch:
HI
: High rate, 100% rate on aileron, elevator and rudder
LO
: Low rate, 70% rate on aileron, elevator and rudder
The default is
HI
.
Generally, different rates are required for different types of flying. For example, low rate
(smaller control surface angles) is required for flying at high speeds whereby the
model's response becomes more sensitive. On the other hand, high rate might be
required for flying slower aggressive acrobatic maneuvers such as hovering thereby the
model may not be as sensitive.
To change the rate on aileron, elevator and rudder, use a small screwdriver to move the
switch to
HI
or
LO
.
Servo Reversing
GAVIN-6A features servo reversing on channel 1 to channel 4. The servo reversing
switches (
AIL
,
ELE
,
THR
, and
RUD
) are located at the lower front of the transmitter and
are used to change the direction of each channel (aileron, elevator, throttle, and rudder
channel). Status of each switch:
REV
: It means the servo direction of the channel is the normal.
NOR
: It means the servo direction of the channel is the reverse.
The default is
NOR
.
To change the switch position to normal or reverse, use a small screwdriver to move the
switch to
REV
or
NOR
.
Mixing
GAVIN-6A offers Elevon (Ailevator) mixing and V-tail mixing. The mix switch is located at
the lower front of the transmitter and is used to activate the corresponding mixing
function. Status of the switch:
AILEVATOR
: Activate the Elevon mixing.
OFF
: Disable the mixing function.
V-TAIL
: Activate the V-tail mixing.
The default is
OFF
.
Elevon Mixing
Corresponding model type: airplane, delta wing.
Elevon (also called delta wing) mixing mixes channel 1 (aileron) to channel 2 (elevator)
allowing the elevons to operate in unison (as elevators) or in opposition (as ailerons). To
activate the Elevon mixing, use a small screwdriver to move the mix switch to the upper
(
AILEVATOR
) position.
V-tail Mixing
Corresponding model type: airplane, V-tail.
V-tail mixing mixes channel 2 (elevator) to channel 4 (rudder) allowing the ruddervators
to operate both as rudders and elevators. To activate the V-tail mixing, use a small
screwdriver to move the mix switch to the lower (
V-TAIL
) position.
