The PCTx is a USB HID device. Windows XP to Windows 10 are compatible. Software is also available for Linux and MacOS, see the software section for details. An R/C transmitter with a trainer port capable of accepting a PPM signal is required. Transmitter modules will work but usually require more work than just plugging in the PCTx.

The PCTx comes with 1 of the following plugs standard. Please see the adapters section if you would like multiple plug styles. Adapters are only available for mono PCTx units.

The PCTx is compatible with most radio brands:

  • Futaba
  • Airtronics
  • JR
  • Spektrum
  • Hitec
  • Tower Hobbies
  • Multiplex
  • ESky


Important Note:

If your radio is not listed the PCTx may still work however it is not tested by Endurance R/C. If your transmitter has a trainer port and can accept a PPM signal then the PCTx should be compatible. However due to the number of different buddy port protocols appearing on the market today we cannot guarantee compatibility with all radios. Please be sure to check your radio's manual before ordering to determine if your radio can accept a PPM pulse.
