Why MUST the 7.2v battery be attached to operate servos on the RC?

No, that's incorrect. I have been driving our robot all week with no backup battery and it works fine. Servos won't move unless the backup battery is connected, but Victors and Spikes do work.

Umm, please go back and have a look at the entire message. You'll see that I was replying to KenWittlief's statement: "are you saying a Hitech servo will not work on the RC unless you have both the 12V and 7.2V batteries connected?". In this context, I am not incorrect.

Whoops -- I was reading so fast last night I totally misread your post. Please forgive me. I should've noticed who's post I was reading.
