Small Update

First off, it was found that the perf board was overly complicated. One of the four and gates on the IC chip was fried pulling the signal to ground. This lead to the idea of tieing the 3V3 logic to the ESC's and seeing what happened. Happily this worked without an issue, meaning that the 5V logic level shift was completely unnecessary. This was originally done before the frequency issue was known so the problem was a bit misunderstood, but because the IC chip is fried a new board needs to be made. This will lead to a more simplistic board that also will hopefully have the zener diode circuit on there somewhere.

The current issue being fought. Transmitting and receiving data with Xbee's simultaneously. They appear to have major issues when these two states are happening rapidly between three different devices. The issue that happens with this environment is the Stellaris Xbee no longer holds any data, the only solution to this issue is the Stellaris transmitting no data. Once the Stellaris stops transmitting the problem goes away but for constant data transmission there is currently a major issue.
