Cool, let us know if you get it. It would be interesting to know what
nifty parts it has. I had a tough time deciding between the front end
loader and the tow truck. Both appeared to have the pneumatics and extra
parts that I wanted to use with the RIS. Price made the decision for me.
By the way, does anyone have a good design for using pneumatics with the
RCX? I would ideally like to use one motor to both power the compressor
and to activate the air switches. An electrical air switch sure would be nice.
