LOW BATTERY ALARM
When the flight battery voltage gets low, the drone will beep to indicate that it
needs to land soon.
WARNING – Do not continue flying the Indorfin until the battery voltage is too
low for the drone to stay in the air. The battery can be damaged if the voltage
drops below 3.0 volts per cell (9 volts).
BETAFLIGHT CONFIGURATOR INSTALLATION
The Indorfin flight controller has Betaflight firmware loaded. To test the controls
and make changes to the settings, the Betaflight Configurator app must be loaded
on your PC. Download and install the Betaflight Configurator app from the Chrome
Web Store. Open the app and click on the link for the latest CP210x driver. Install
the driver and connect the Indorfin to your PC with a micro USB cable (not included).
After the drone is connected to your PC, select the COM port in in the Betaflight

6
drop down box and click on the Connect Button. The app will display a virtual
model of the drone when it is connected.
Betaflight has a link to the Wiki that describes the features of the app. There are
also several videos that explain how to setup and use Betaflight. Search for the
Betaflight version you are using.
The flight battery will be needed to power the Indorfin if the receiver connections
or the motors are being tested. NOTE: Always remove the props from the Indorfin
before connecting it to Betaflight when it is powered with the flight battery.

the wall adapter. The power LED will illuminate solid RED. Plug the white balance
plug on the battery to the 3S port on the charger. When charging, the charge

7
status LED will illuminate solid RED. When charge is
complete the LED will change to solid GREEN. Typical
charge time of a depleted battery is approximately
75 minutes.
NOTE: A blinking red charge status LED indicates a
charging error.
●NEVER leave the battery unattended
while charging.
●ALWAYS unplug the charger from the
outlet and the battery when charging
is complete.
●NEVER charge a puffed or damaged
battery.
NOTE: It is normal for the charger to get warm during the charging process.
BATTERY INSTALLATION

FPV CAMERA
The Indorfin has a built in FPV camera and a 40 channel VTX that transmits on
the A, B, E, F and R bands. Your monitor or goggle must be set to the correct
band and channel to display the video feed from the camera. If a Tactic FPV-RM2
LCD monitor is being used:
1. Power up the Indorfin.
2. Attach the FPV monitor antenna and turn on the monitor.
3. If the monitor is not displaying a signal from the drone, hold the “B” button
on the monitor for 2 seconds and release it. The monitor will scan all the
channels and lock onto the closest signal.
4. Place the monitor in the cradle on the transmitter or inside the goggle.
If the band or channel on the VTX must be changed –
1. Remove the 6 screws
that hold the upper
body to the chassis and
turn the part over so the
bottom of the camera is
exposed.
2. Power up the drone and
hold the camera button
for a second to change
the band. A quick tap on
the button will change the channel. The camera LED will display a letter for
the band and a number for the channel that is selected.
3. Replace the upper body when the desired band and channel have been
selected.
Lines and static on the feed from the FPV camera are normal and will be more
frequent as the Indorfin gets farther from the pilot. The typical FPV range is around
200 yards depending on how close sources of interference like Wi-Fi routers are
to the flying area. If you have access to large open area to fly, replacing the
antenna on the monitor with a circular polarized antenna like the Tactic FPV
Cloverleaf Antenna (TACZ5305) will increase the FPV range.
IMPORTANT NOTICE! The Indorfin with the 200mW VTX requires
a HAM Technicians license to operate legally in the USA. This involves
a 35-question multiple-choice test and a small fee. You can contact an amateur radio club in your
area for assistance or visit this link:
http://wireless.fcc.gov/services/index.htm?job=licensing_2&id=amateur
arrl.org/getting-licensed
Customers outside of the USA should understand and follow all telecommunications or other regulations
in your area.

FLYING
FLIGHT CONTROLS
DUAL RATES
The stock transmitter for the Indorfin has two settings for the sensitivity of the
controls. When the switch is pushed toward the back of the controller, it is in the
high rate position. The controls are at the maximum sensitivity.
Low Rates – when the switch is pulled forward, it is in the low rate position. The
controls are at the least sensitivity.
If more or less sensitivity is desired, the control rates can be changed in Betaflight
on the PID Tuning page. Increase the RC Rate to make the controls less sensitive
at mid-stick. There is one setting that adjusts both the pitch and roll rates. Increase
the Super Rate to make the controls more sensitive at full stick.
FLIGHT MODES
The Indorfin has 3 different flight modes.
Mode 1 – Angle Mode: (Accelerometers On) Angle Mode is for the pilot
that is moving up from an entry level drone. This mode will level the Indorfin when
the right stick is centered. It also has a maximum tilt angle of 55° so the drone
cannot flip upside down.
Mode 2 - Horizon Mode: (Accelerometers On) Horizon Mode should be
selected when the pilot wants to flip and roll the Indorfin but still have the drone
level itself. There are no limits on the tilt angle in this flight mode.
To flip or roll the Indorfin, move the right stick as far as possible in the direction
that you want to flip. At the same time, advance the throttle to 100%. When the
drone has rotated 90°, reduce the throttle to about 25% and center the right stick.
When the Indorfin is at 270°, move the throttle back up to midstick.
Mode 3 – Acro Mode: (Accelerometers Off) Acro Mode is for the pilot
that wants the Indorfin to be as maneuverable as possible. The Indorfin will NOT
level itself in this flight mode and there are no limits on the tilt angle.

10
ACRO-MODE FLIGHT
To hover, quick movements with right stick in the opposite direction of any drifting
will be needed to keep the Indorfin level.
To fly the Indorfin in this mode, move the right stick in the desired direction and
adjust the throttle position as needed to maintain the Indorfin’s altitude. Move the
right stick back to center and hold the throttle at its current position to maintain
that speed and direction. To reduce the drone’s speed, move the right stick the
opposite direction. When the drone is moving at the desired speed, center the
right stick.
The technique for flips is the same as in Horizon Mode.
You should be comfortable flying and flipping in Horizon Mode before attempting
to fly in Acro Mode. When learning to fly in this mode, take off in Angle or Horizon
mode and switch to Acro when you are in the air. Be prepared to switch back to
Horizon mode when you get into trouble. Fly over tall grass to help protect the
Indorfin from crash damage. The dual rate switch should be in the low rate position
to help keep the drone’s speed low.
FPV FLIGHT
Flying FPV can be difficult because it is hard to determine altitude with just the
camera. Practice with a spotter so they can provide warnings and assist with
locating the drone when it crashes. If possible, fly in an open area with tall grass
to help protect the Indorfin from crash damage.
Stay low, use low rates and mode 1 or 2 until you can control the drone’s height
without assistance. When you are comfortable flying in an open area, practice
flying a pre-set course.
MOTOR ARMING - D/R HIGH, YAW RIGHT, FULL DOWN THROTTLE
While the throttle is at its lowest setting, hold the yaw control to the right to arm
the motors. The Indorfin will beep to indicate that the motors are armed, but the
motors will not spin until the throttle stick has been moved up. The motors cannot
be armed while the dual rate switch is in the low rate position. If flying with the
controls in low rate mode, arm the motors while the switch is in high rates and
select low rates after the motors are armed.
To disarm the motors, move the throttle to its lowest setting and hold the yaw
control to the left. The motors will disarm automatically if the throttle is held down
for 5 seconds. The dual rate switch must be in the high rate position so the yaw
control can disarm the motors.
TAKEOFF AND LANDING
Turn on the transmitter and connect the flight battery to the Indorfin. Place the
drone on a level surface and let it calibrate the sensors. The flight controller must
not move for a few seconds to allow it to complete the setup procedure. The
Indorfin will beep three times when it is ready to fly.

11
Arm the motors by holding the left stick in the lower right corner until the Indorfin
beeps once. The motors are now armed. The motors will not spin until the throttle
is above 0%. Advance the throttle until the motors start to spin. After verifying that
all 4 motors are spinning, continue moving the throttle up until the drone is at least
2 feet above the ground. Note: the motors will automatically disarm if the throttle
is left at 0% for 5 seconds.
To land, hover the Indorfin over the landing spot and slowly reduce the throttle.
When the drone is on the ground, hold the left stick in the lower left corner until
the drone beeps. Always remove the battery and charge it when the flight is
completed. Note: if the throttle is held at 0% for 5 seconds, the motors will disarm
automatically.
FAILSAFE/BEACON
The Indorfin flight controller is programmed to stop the motors within 2 seconds
of losing the signal from the transmitter so the drone cannot fly off. The Indorfin
will beep every second when in failsafe mode. If you are having problems locating
the drone after a crash, try turning off the transmitter and listen for the beeps.
LOW BATTERY ALARM
When the flight battery voltage gets low, the drone will beep to indicate that it
needs to land soon.
WARNING – Do not continue flying the Indorfin until the battery voltage is too
low for the drone to stay in the air. The battery can be damaged if the voltage
drops below 3.0 volts per cell (9 volts).
MAINTENANCE
INSTALLING PROP GUARDS
To install the prop guards, remove
the two 5mm motor mount screws
next to the landing gear.
Slide the prop guard over the
landing gear and snap it on the
top of the arm.
Install (2) 8mm screws to hold the
prop guard in place.
NOTE: A little thread lock compound should be applied to the new screws to
help prevent the screws from coming loose.

12
PROPELLER REPLACEMENT
The propellers should be checked for
damage after each flight. If the
Indorfin is suddenly making a strange
noise while in flight, a damaged prop
is the most likely cause for the
vibration. Also, make sure that the
screws that hold the propellers in
place are not loose. If the screws will
not remain tight, put a little thread
locking compound just on the last two threads of the screw.
The CW props should be installed on the front left and rear right motors marked
1104 – 4100KV CW.
The CCW props should be installed on the front right and rear left motors marked
1104 – 4100KV CCW.
FLIGHT CONTROLLER REPLACEMENT
If the flight controller has been damaged and needs to be replaced:
1. Remove the 6 screws that hold
the Upper and Lower Body
parts to the frame.
2. Unplug the camera and put
the upper body aside.
3. Remove the flight battery
connector cover.
4. Remove the bottom case from
the frame.
5. Remove the 4 speed controls
from the arms.

7. When the ESC stops beeping, move the Master control to its lowest setting.
8. Slowly move the Master control up again and verify that all four motors
start to spin at the same time.
EXTERNAL RECEIVERS
An external receiver can be connected to the Indorfin using the 4 pin port on the
bottom of the drone and the RX Extension cable (RISE2141).
Serial Receivers – S.Bus, DMX, I-bus, etc. receivers should use the ground (black
wire), power (red wire), and the S.Bus (white wire) connectors on the cable. The
S.Bus wire goes to the signal pin on the receiver. The yellow wire is not used with
these receivers.

14
Connect the Indorfin to Betaflight and make the following changes.
The Serial Rx switch must be
turned on for UART2 on the Ports
page.
The appropriate Serial Receiver
Provider must be selected on the
Configuration page in the
Receiver section.
PPM Receivers will use the
ground (black), power (red), and
PPM (yellow) wires on the RX
cable. The PPM wire goes to the
signal pin on the receiver. The
white wire is not used.
Connect the Indorfin to Betaflight
and change the Receiver Mode
on the Configuration page to PPM.
PWM Receivers will need to use a PWM to PPM
converter. The same wires used with the PPM
Receiver can be soldered to the PPM cable that
comes with the converter. Another option is order
the RISE Camera Cable (RISE2114). The wires will
have to be moved for the cable to work correctly.

Spektrum Satellite Receivers will
need a cable like the 6” Remote
Receiver Extension – SPM9010
that can be cut and soldered to
the flight controller.
On the Betaflight Ports page, the
Serial Rx button for UART2 needs
to be turned on and the one for
UART3 turned off.

16
On the Betaflight Configuration
page, the appropriate Spektrum
receiver must be selected in the
Serial Receiver Provider part of
the Receiver section
(DSMX=2048 or DSM2=1024).
On the Betaflight Receiver page, the Channel Map needs to be changed to Spektrum.
To bind the Rx to the Tx, go to the Betaflight CLI page and type the following
set spektrum_sat_bind = 9 if you have a DSMX satellite receiver
set spektrum_sat_bind = 5 if you have a DSM2 satellite receiver
save
After the flight controller has rebooted, unplug the USB cable and plug it back in
after a second. The LED on the receiver should start blinking to indicate it is in
bind mode. Turn on the Tx while holding the bind button. When the process is
complete, the LED on the receiver should stop flashing.
Go back to the Receiver page
and verify that inputs from the
Tx are being received. Check the
lowest value for the throttle. The
setting in the “Stick Low”
Threshold window must be
greater than the lowest value for
the throttle. If the throttle (and
other controls) do not go below
1100, the travel setting in the
transmitter may need to be
increased before the “Stick Low”
Threshold is changed. Click on
the Save button to save any changes in the Flight Controller.
After control inputs are being received on the Receiver page, go back to the CLI
page and type the following to turn off the bind mode.
set spektrum_sat_bind = 0
save
CONTROL INPUT TESTING
After a new receiver is connected, use the following procedure to test the flight
controls. If any control is moving in the opposite direction, reverse that channel in

17
your transmitter.
1. Remove the props from the Indorfin.
2. Open the Betaflight Configurator app.
3. Connect the Indorfin to the PC with a micro USB cable.
4. Connect the flight battery to the Indorfin.
5. Go to the Receiver page.
6. Select the appropriate Channel Mapping option. The graphs for roll and
yaw channels should move to the right when the sticks are moved to the
right. The graphs for the pitch and throttle channels should move to the
right when the sticks are moved up. The movement of the virtual model can
also be used to verify the correct control inputs are being received.
7. Arm the motors by holding the left stick in the lower right corner. After the
Indorfin beeps, advance the throttle and verify that all 4 motors are
spinning. Disarm the motors by holding the left stick in the lower left corner.
8. Push the flight mode switch toward the back of the transmitter (stability
mode). The channel 5 graph (aux1) should be to the right.
If all the controls are responding correctly, unplug the Indorfin, disconnect the
battery and install the props.
CALIBRATE ACCELEROMETERS
If the Indorfin has been crashed or will not remain level when hovering, the
accelerometers may need to be calibrated. Connect the Indorfin to your PC and
open Betaflight. When the drone is connected, place it on a level surface and
click on the Calibrate Accelerometer button at the top of the screen. When the
calibration is complete, the pitch and roll values should be less than 1.0 deg.
BLACKBOX RECORDING
The Indorfin has an onboard flash memory chip that can record several minutes
of flight data. To use this feature:
1. Open the Blackbox page in Betaflight.
2. Set the Blackbox logging device to Onboard Flash.
3. Set the Blackbox logging rate to 500 HZ. This rate will not affect the CPU
performance.
4. Click on the “Save flash to file” button to save previously recorded data if
needed. Click the “Erase flash” button to make room for new data. The
Blackbox will start to record as soon as the motors are armed.
