FUTABA TRANSMITTER AND RECEIVER SETUP (CONTINUED)
19
Some Futaba S.Bus receivers will need to be configured and set up to output the proper S.Bus signal and order. Consult your
receiver manual for information on this process. If you have questions on binding your particular receiver and transmitter,
consult your transmitter and receiver's instruction manual.
End Point Sub-Trim and Throttle Reversing Setup
Futaba transmitters will need to have their sub-trims and travels adjusted to a range that the FLEXF3 is expecting. Throttle
direction may vary depending on your particular transmitter. Follow the instructions below for proper adjustment of these
settings.

Open the Betaflight Configurator or the SpeedyBee mobile application. Connect the USB to your FLEXF3 and your PC
or connect via bluetooth with your mobile device. Click "Connect" in the top right corner of the application.
Navigate to the "Receiver" page.
Once connected, you will see the values in the chart change when you move the sticks on the transmitter. Take note of
the Roll, Pitch, Throttle, Yaw and CH6 values.
Once complete, click "Disconnect" and remove the USB cable or bluetooth module from the FLEXF3.
With the Flight Configuration switch set to 45 Degree "Magic" Configuration (CH6 - middle switch position),
adjust the subtrim in the transmitter until Roll, Pitch, Yaw and channel 6 (CH6 is Betaflight AUX 2) show
"1500" at center stick in the Betaflight or SpeedyBee monitor.
High throttle should read as a higher value (2000), whereas low throttle should read as a lower value (1000).
Reverse the throttle direction in the transmitter if necessary to achive this.
Deflect each stick fully in both directions (including throttle). Adjust the travels (ATV) in your transmitter until
you reach 1000 at one end of stick movement and 2000 at the other end of stick movement when looking at
the Betaflight monitor.
