Ok guys, I got my 123 sound chip. I installed it and turned my track recoil off. I like the operation real well now. The sound draw back is since the 123 and the rx18 are both running sound, there is a slight stop of engine sound right after the gun fire sound. I don't mind right now. Maybe next time on the Jumbo I will try out a bendini. Any way enjoy the video.
