I got the one with the Ipod docking station for $90 with the reciever. I want to know what sensors I would need to make use of the dash board. I don't really care about the RPM to much, but I would like to know the speed and temps mainly, and maybe the volts. I have a VXL slash and I did not see telementery labled for it yet. Does the X-01 stuff work on it? Also I can not find any kind of speed sensor. All I have managed to find was temp, volts, and rpm.
