Rick,

I'm not too familiar with the planks....

I only know about the stuff I've bought and tried over the last few months, learning about this hobby.

But from my knowledge you would use the THRO connection. It is my understand that the BATT connection on the AR6100 is ONLY USED for the binding process. Any connection that completes the circuit on those leads will send the AR6100 into binding mode. AGAIN, this is my understanding, and I COULD BE WRONG!!!
