It does not work on receivers for digital servo's. If the radio set has different modulation modes, use FM or PPM modes only. The VRC-3 therefore works with all 27-40-53-72MHz. The VRC-3 USB adaptor works independent of the brand or frequency of your transmitter as it only uses the standardized servo output signals and translates these to the standardized game controller input using the HID protocol. When connected correctly and with the USB plugged into your computer, the device will be recognized by Windows as a standard HID device (Human Input Device), and will be identified as 'VRC USB adaptor 3'. A continuous dimmed red LED indicates that the servo connectors should be plugged in the other way around. Make sure to plug the servo connectors in with the white lead in the same position as your servo cable plus in.Ī flashing red LED inside the adaptor indicates that the adaptor has been connected correctly. Simply plug the 2 servo connectors into the receiver: the 3-lead into the steering slot, and the single lead into the throttle-brake slot. The VRC-3 adaptor does not work with 2.4Ghz systems. It is specially developed for VRC for optimized performance and user friendliness. This is the 3rd generation of the popular VRC adaptor: VRC-3.
