DX9 Crossfire Disclaimer

By downloading this update (Spektrum DX9 Protocol/CRSF Menu), you agree to
all the terms and conditions associated with the update.
Modification for use of the Team Black Sheep Crossfire System
The TBS Crossfire long range system is intended to provide less latency and greater range than standard
systems in the DX9 radio. However, installing the Crossfire system requires soldering a new serial port
onto the transmitter circuit board. We have provided a comprehensive tutorial to perform this
modification on a Spektrum DX9 Transmitter correctly. Please be aware that any self-modification of the
transmitter will void your transmitter warranty. Future service on a self-modified transmitter will not be
denied, but any future service performed will not be covered under warranty. As a result, Horizon
strongly recommends sending your Spektrum radio in for service and allowing our professional service
technicians to perform the Crossfire system installation and preserve your warranty. Click here to start
the service request process. Please include a note in the service request asking for this modification.
Once we receive your Transmitter, an authorized Spektrum Service Technician will perform the
modification and confirm that the Transmitter functions properly post upgrade. Once the modification is
completed, your radio will have a common servo connector leading out the back of the radio that offers
serial port signal and ground. Use this plug to connect and communicate with your serial input module.
The cost for this modification is $75 plus shipping and is currently only offered for the Spektrum DX9 and
DX9 Black Edition transmitters.
