Well, from what i have seen it is the same old multi stepped sound used in every other system other than El-Mod and the DBC3 with the Benedinni system. I preffer a system where you can actually load your own true engine and cannon sounds. These are a great improvement over the standard HL offering but i really like the DBC3 the more I see and use it. No it is not a low buck solution but i am not looking for one. Most of my tanks are set up with Tamiya systems and there is no low buck about that.<div> What I would say was the most desirable system is one that gives you the abillity to add your own sounds which ever system that may be for any given hobbiest.</div>
