Dan is too kind to mentioned this, but if you think you want to upgrade past just the hobby grade Tx and interface with a Benedini, you can skip the DBC 2 and go to the 3 (or BARC)

Dan got together with David (DBC) and Thomas Benedini to get the two working together via programming, which eventually led to the BARC system he sells.

I built a 2 from David's kit, but almost immediately went to upgrade by getting the 3 chip.

Just throwing that out there, the Benedini is the pinnacle of RC sound, whether tanks, AC, ships, whatever...
