VRC did team up with 9-turbo to sell them for 60 Euros after some time. So, no official dongles were available anymore, and even some of the 3rd party adapters went out of stock like the MHW and 9-turbo. Unfortunately, the official VRC dongle went out of production due to permanent supply issues: The sim allows you to use your real life radio control transmitter and receiver by the use of a dongle that plugs into the USB port of your computer. It is a very faithful and complex simulation of R/C car racing. I race a simulator for R/C cars called VRC Pro (Virtual Radio Control). You can use the same DIY instructions below or I build, program, test, and ship one to you for just $40 in the US! Solid 700+ frame rate showing in VRC instead of variable. New V2.0 with updated code, new board that eliminates the USB cord, new connectors for easier channel connections.
