How can I connect my transmitter?

To connect your transmitter for operation with REFLEX XTR² you might require a standard gamecontroller compatible USB simulator interface. These are available in a variety of designs from various suppliers. Here you can find some of the available products:

A highly versatile and widely used interface is the RX2SIM Wireless Multi-Sim Adapter from RCWARE (RCWT300195). It allows you to control wirelessly when connecting a receiver compatible with your transmitter. Or if your transmitter is equipped with a trainer socket, you can connect it also directly by cable.

If you have a MULTIPLEX remote control, the MULTIflight Stick from MULTIPLEX (85147) is to be recommended. All M-LINK transmitters can be connected wirelessly to the computer.

SPEKTRUM offers the Wireless Simulator USB Dongle (SPMWS2000). This connects wirelessly to all DSM2/DSMX compatible transmitters. Alternatively, HobbyKing offers the DSMX/DSM2 protocol USB wireless dongle (9171000899-0).

For FUTABA transmitters using the S-FHSS protocol the FUTABA Sim Control (WSC-1) is offered. This USB module has an 8-channel receiver integrated and thus also allows wireless connection of the transmitter.

For transmitters with FrSky protocol, HobbyKing also offers the FrSky protocol USB wireless dongle (9171000897-0). 

If your transmitter is equipped with a trainer socket, the
USB Simulator Cable XTR/AeroFly/FMS from HobbyKing (XTR01) is a very inexpensive alternative. Transmitter connection cable and adapters for various transmitters (except MULTIPLEX) are included.

Some remote controls from FrSky, RadioMaster, Jumper, Jeti, MULTIPLEX,  SPEKTRUM and Graupner can also be connected directly via USB cable, you don't need an additional interface for such transmitters.

Does REFLEX XTR² work on an Apple Mac computer?

Yes, you will need to install Microsoft® Windows® on your Mac using Boot Camp. Virtual machines such as Parallels Desktop® or Virtual Box are not suitable.


Does REFLEX XTR² work on Linux?

Yes, using PlayOnLinux you can install and run REFLEX XTR² on almost any Linux distribution. To do so, start the PlayOnLinux manual installation wizard and install REFLEX XTR² in a new virtual drive.

Other pilots cannot connect to my flight convention or participation in a flight convention fails with the error message "The connection to the flight convention could not be established".

In order to establish the network connection to the other participants, you must create two port forwardings in your router with the following DirectPlay8 settings:
  • Port 6073 UDP, inbound/outbound
  • Port range 2302-2400 UDP, inbound/outbound
Please note that port forwarding requires that you have assigned a static IP address to your computer. For more information on port forwarding, you may refer to the website portforward.com for example.

Furthermore, your firewall must be configured to allow the following apps to communicate through the firewall:
  • REFLEX (c:\program files(x86)\reflex\simulator\reflex.exe)
  • Microsoft DirectPlay8-Server (c:\windows\syswow64\dpnsvr.exe for 64 bit Windows® or respectively c:\windows\system32\dpnsvr.exe for 32 bit Windows®)
