This guide provides instructions to help you program the Detrum GAVIN-6C for an airplane.
Additional information can be found in the manual included with the radio.
Review the Transmitter’s Controls
1. Power switch—push the switch up to turn the transmitter on.
2. Status light—illuminated when the transmitter is turned on.
3. Trim buttons—push to set the trim for the associated channel.
4. Control sticks—control the channel to which they are connected.
5. GEAR switch—a two-position switch that is usually used for retracts.
6. TRAINER switch—a two-position switch that is spring-loaded; when held against the
spring, the transmitter passes control to another transmitter to which it is connected. You
also use this to bind the transmitter to a receiver.
7. FLAP switch—a two-position switch that can be used for flaps; however, a three-position
switch is more typical for flaps (you can use the FMOD switch for flaps).
8. HOLD switch—a two-position switch that activates throttle hold.
9. FMOD switch—a three-position switch that can be used for a variety of functions.
10. Display screen—displays different pages of information while you are controlling a
model or programming the transmitter. After a time of inactivity, the screen dims. Press a
button to return the screen to full brightness.

Review the Home Screen
1. System timer—how long the transmitter has been turned on.
2. Battery status—how much charge remains in the batteries by percentage and icon.
3. Dual rate status—when the two bars are the same height, dual rates are turned off and
100% of maximum control movement is provided; when the left bar is half height, dual
rates are turned on and 60% of maximum control movement is provided.
4. Hold indicator—when HLD is displayed, throttle hold is on and the motor won’t spin
when throttle is applied; when NORM is displayed, the throttle is active.
5. Percent of throttle—indicates how much throttle is being applied.
6. Timer 1—displays a countdown or count up timer, typically triggered by throttle or
HOLD switch position. When the timer expires, you hear a tone and the timer flashes.
7. Timer 2—provides a second timer with the same capabilities as timer 1.
8. Trim indicators—the shaded part of the trim indicator indicates how much trim is applied
to the associated channel and in which direction. When you are setting trim, the
numerical value is displayed at the end of the trim indicator.
9. Active model—you see the name of the active model, which means the model that can be
flown or programmed.

6. Turn the transmitter off.
7. Connect the receiver to at least one servo and to the ESC.
8. If you are using a receiver that has a BIND port, follow steps 9 and 10; if you are using a
receiver with a Bind button, follow steps 11 and 12 instead.
9. Insert the Bind plug into the BIND port.
10. Power the receiver by connecting a battery to the ESC. The Bind light on the receiver
flashes indicating that it is in Bind mode. Skip to step 13.
11. Power the receiver by connecting a battery to the ESC. The Bind light flashes rapidly.
12. Hold the Bind button down until the Bind light flashes more slowly.
13. Hold the TRAINER switch in the forward position (toward the front of the transmitter)
and turn the transmitter on. You hear the bind tone on the transmitter and the Bind light
on the receiver becomes solid, indicating the bind process is complete.
14. Move the control associated with the servo you connected to ensure it moves. If so, the
model is bound. If not, repeat this process until it is successful.
15. Power off the receiver and remove the Bind plug (if applicable).
16. Power off the transmitter.
Prepare to Program an Airplane
1. Connect the ESC to the THRO channel on the receiver.
2. Connect the aileron, elevator, and rudder servos to their respective ports on the receiver.
3. Connect the retracts to the GEAR port.
4. Connect the flap servos to the AUX1 port.
5. Turn the transmitter on and use steps 1-5 in the previous task to select the model you
want to program. Confirm that the model you want to program is shown.
6. Put the HOLD switch in the down position (toward the bottom of the transmitter); by
default, the throttle hold is active. Enabling the throttle hold before starting the model
prevents an unintended startup of the prop or EDF, which could be a safety hazard. When
the throttle hold is engaged, you see HLD on the home screen.
7. Connect a battery to the ESC. You should hear the startup tones from the ESC and see a
solid light on the receiver.
8. Check to make sure a spinning prop or EDF won’t be a safety hazard and move the
HOLD switch to the up position to enable the throttle.

9. Slowly advance the throttle until the motor driving the prop or EDF spins; when done,
move the throttle to the off position and re-engage the throttle hold by moving the HOLD
switch to the down position.
10. Systematically check each control surface for movement including rudder, ailerons,
elevator, flaps, and retracts. You can change direction and amount of movement later,
now you are ensuring the transmitter can activate the controls.
11. After you’ve confirmed all the model’s controls are working, you are ready to do the
detailed programming of the model.
If a plane has flaps, you usually want the flaps to be on a 3-position switch (up, takeoff,
and landing). If you connect the flap servos to the AUX1 channel, by default, they are
controlled by the FMOD switch, which is a 3-position switch. If you want the flaps to be
controlled by the FLAP switch, which only has two positions, use the Func Set screen to
set the FLAP switch to the AUX1 channel (this screen is used in the “Set Dual Rates”
task later in this guide).
Program Servo Direction
1. Set the correct direction for each servo using the Rev Set function; to access this from the
home screen, press ENT, select Model Parameter, press ENT, select Rev Set, and press
ENT. You move to the Rev Set screen where you see the current servo direction (Norm
or Rev) for each channel.
2. Check the direction of motion for a control surface, such as the elevator. If the direction
needs to be reversed, perform step 3; if not, skip to step 4.
3. Select the channel for the control surface (such as CH2 for the elevator), and press the
R/+ button. The direction setting changes from Norm to Rev and the servo moves in the
opposite direction.

4. Check the direction of motion for another control surface, such as the ailerons.
5. If the direction needs to be reversed, select the corresponding channel on the Rev Set
screen and press the R/+ button.
6. Repeat steps 3 and 4 until you are sure all the control surfaces move in the correct
direction.
7. When you’re done setting direction, press EXT three times.
Program Servo Range of Motion
1. Set the range of motion for each servo using the End Point function; from the home
screen, press ENT, select Model Parameter, press ENT, select End Point, and press
ENT. You move to the End Point screen where you see the current range for each
channel indicated by the LOW and HIG settings for each channel. LOW indicates the
negative side of the range while HIG indicates the positive side. Each range can be set
between 0 and 120.
2. Select the channel and range of motion you want to set, such as CH1 LOW.
3. Press R/+ to increase the range in that direction (the maximum is 120) or L/- to decrease
the range (the minimum is 0).
4. Select the other direction for the channel you selected in step 2, such as HIG.
5. Press R/+ to increase the range in that direction (the maximum is 120) or L/- to decrease
the range (the minimum is 0).
6. Repeat steps 2-5 until you have set the range of motion for all of the channels you are
using.
7. Press EXT three times to move back to the home screen.
