You’re using a Frsky receiver?

Receiver for regional FCC or LBT firmware?

ALL iFlight default models are shipped with FCC firmware for global customers from our website. The European LBT standard can be selected as an option.

Transmitter and Receiver FCC or LBT have to match! Updating might be necessary.

Your local retail shop might have ordered the local standard, please double-check.

Transmitter (Radio) is a Frsky or a Multiprotocol transmitter that supports the Frsky protocol D8 or D16?

Frsky receivers come in several firmware options. iFlight ships all receivers with the latest 2.x ACCST firmware!

ACCST (Standard) ACCESS (since 2019)

ACCST Firmware versions 2.x and

1.x can’t bind. ACCST and ACCESS mixed not compatible.

The transmitter and Receiver both need matching firmware!

Updating the Transmitter firmware might be necessary, relatively easy to do.

Multiprotocol receivers can select the firmware and protocol before the bind.

The receiver is D8 or D16?

The D8 or D16 protocol needs to be selected on the radio to bind.

Differences:

D8 (failsafe set on the receiver, max 8 channels)

D16 (failsafe set with the transmitter, max 16 channels)

Latency:

D16 set to only 8 channels has lower latency than D16 with all 16 channels.

Multiprotocol radios need to be set up for the binding process. Option “Frsky” for version 1.x or “FrskyX2” for version

2.x. Mismatching firmware will not

bind to your receiver.

Frsky radios need to be set up with D16 protocol only, Multiprotocol radios check the D16 option as well.

Reduce channels to 8 (1-8) for lower latency, or select 16 for more control channels.

Receivers need to be powered on while holding the bind button.

Release it after 2-3 seconds. The receiver should show a green light. The binding mode is active!

(please check the manual for specifications)

Scroll down and select Failsafe “No pulses”.

Scroll back to the Bind option on your radio and start.

Use prompt option “Ch1-8 Telem OFF” if appears.

Telemetry (Telem ON) needs an additional wire (S.Port) or different firmware (F.Port).

Please check your build or product specifications to confirm.

Common XM+ receivers have no telemetry, R-XSR depending on the flight controller and setup.

A strange beeping will start.

The binding mode is active!

The second LED beside the green one on the receiver will turn into solid red, with no flashing.

The transmitter will stop to beep if you click the Bind option again or stop itself after a while.

Power cycle your receiver off/on and there should be one green LED only for the successful link.

Transmitter shows indicator on the screen.
