This Document is meant to educate how a Spektrum DX9 owner can upgrade their transmitter to
provide a serial data port for use with the Team Black Sheep Crossfire Module.
Currently there are 2 methods.
Please read this disclaimer before using a Spektrum DX9 with the TBS Crossfire Module.
Using the Crossfire firmware
By downloading this firmware, you acknowledge that you understand the use and liability of
long range radio systems, such as the Team Black Sheep Crossfire long range system, and that flying
beyond line of sight can be hazardous and potentially illegal. Horizon Hobby in no way endorses
hazardous and/or illegal activities, and it is the user's responsibility to understand and follow all local
laws and regulations. Furthermore, Horizon is not responsible for any loss of control that may result in
damages or loss of property when using external RF modules with Spektrum Equipment.
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, and repairs will be
billed accordingly. 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
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.
