3. IFLY-4 Radio Transmitter Configuration (Recommended)

The recommended method for setting and configuring the IFLY-4 is by connecting to the

IdeaFlyTools software on a computer. If you have not already done so, pls go to Section 3.0 to

install the IdeaFlyTools software onto the Windows PC.

An alternative method is shown in section 1.3.

SAFETY WARNING – REMOVE ALL PROPELLERS FROM THE IFLY-4 DURING SETUP

3.1 Using a standard mini USB cable (not supplied), connect IFLY-C4 Flight Controller to a

computer. The IFLY-C4 mini USB port can be found on the side of the unit.

3.2 RUN IdeaFlyTools on the computer.

3.3 Switch ON your radio transmitter.

3.4 Install the flight battery and plug into the IFLY-4.

3.5 You should be presented with the following screen on your computer;

3.6 Click the ‘joystick’ tab to calibrate your transmitter.

3.7 Click the ‘Calibrate joystick’ button to start calibration of your transmitter.

3.8 Move all sticks of your transmitter from its MIN to MAX positions several times,

including cycling the switches.

3.9 Observe the final positions of the bars when you are MID-stick. It should be

showing at mid position of the slider bars.

3.10 Click the “Complete Calibrate” button to complete calibration of the transmitter

endpoints.

3.11 Now move each axes of your transmitter stick separately and observe the direction

that the slider bar moves is in accordance with the indication on the screen (eg.

TX Aileron LEFT, moves the slider bar LEFT etc). If the slide bar does not move in

the correct direction: REVERSE the direction of that channel on your

TRANSMITTER.

3.12 Repeat step 12, until all directions have been set correctly. Note: the MODE

channel will correspond to the channel which you connected the ‘F’ wire to.

Always set the MODE to a default position of BALANCE, so auto-stabilisation is

ON.

3.13 When you have finished, click the “Write” button to transfer the settings back to

the IFLY-C4. The IFLY-C4 will beep.

Your IFLY-4 is now fully configured. Install the propellers back on and you are ready to fly!

4. IFLY-4 Radio Transmitter Configuration (Alternative)

If you do not have access to a computer, it is possible to setup your radio transmitter manually.

However, this should only be done by an experienced person. The propellers MUST be

removed during this setup.

READ THIS SECTION COMPLETELY BEFORE ATTEMPTING TO START THE CONFIGURATION

SAFETY WARNING – REMOVE ALL PROPELLERS FROM THE IFLY-4 DURING SETUP

1. Unfold and position the IFLY-4 in a stable horizontal position without the landing gear

installed.

2. Set your radio transmitter THROTTLE to LOWEST position – DO NOT CHANGE FROM THIS

LOWEST THROTTLE POSITION OR MOVE THE IFLY-4 AT ANY TIME DURING THE SETUP.

3. Switch ON your radio transmitter.

4. Install the flight battery and plug into the IFLY-4.

5. With THROTTLE LOW, move the RUDDER stick to the LEFT. Observe if the motors start to

spin slowly? If YES, your THROTTLE and RUDDER directions are correct. Go to step 8.

6. If the motors did not start, move your RUDDER stick to the RIGHT. Observe if the motors

start to spin slowly? If YES, your THROTTLE direction is correct, but your RUDDER direction

is reversed. REVERSE the RUDDER direction on your radio transmitter. Go to step 8.

7. If the motor did not start at all during step 5 or 6. Your THROTTLE direction is reversed.

REVERSE the THROTTLE direction on your radio transmitter and repeat from step 5.

8. You can stop the motors spinning at any time by moving the RUDDER in the opposite

direction to which turned the motors ON.

9. The next steps require the IFLY-4 to be in an ARMED state. To go into ARMED state, move

the THROTTLE to LOW (should be at that position already) and move the RUDDER LEFT

(momentarily), then return RUDDER to neutral.

10. Now move the ELEVATOR stick FORWARD. Observe if the REAR motors speed up? If YES,

your ELEVATOR direction is correct. If the front motors speed up instead, you need to

REVERSE the ELEVATOR direction on your radio transmitter.

11. Now move the AILERON stick LEFT. Observe if the RIGHT motors speed up? If YES, your

AILERON direction is correct. If the RIGHT motors speed up instead, you need to REVERSE

the AILERON direction on your radio transmitter.

12. Finally, you can only set the Flight Mode switch direction by carefully testing out during

initial flying.

Update – Firmware version v3.17 or higher

If your IFLY-C4 has been updated with firmware v3.17 or higher. You can check the flight mode

you are flying by watching the flashing LED lights below the motors.

Single flash – Manual mode (non-stabilised) mode,

Double flash – Balanced mode (stabilised) mode.
