I started back on my Vex setup and went with a very basic code for right now.
Chris James knows away to code 2 Vex and use 1 controller. I need to contact him and see if this is something I can figure out and I may go this route.
This would make it nice to run the body off 1 Vex and the dome off another Vex.
I went to Radio Shack and bought a battery connector, So I can run the Vex off a 12v. battery with a Universal power supply. The supply allows me to convert the 12v. down to 7.5v.
I did this because I'm trying to eliminate so many different batteries in R2.
