It is not as simple as using the servo to control the elevation with the DBC. You would have to map it to a stick that didn't want to return to center, so that when you moved it up it would stay up. You would then have to map the cannon sound somewhere else.

I have talked to David and the DBC3 could be reprogrammed to work like this, but then it would not be plug and play with the HL so it is not as easy as one would think. I personally don't mind the cycle elevation on the gun barrel. Typically in IR fights the elevation is not that big of an issue. One of the selling features of this DBC is that it is plug and play with no mods to the Heng long system, so I don't want to lose that.
