Which battle system should i eventually get because whatever tank i buy, it will most likely be heng long, so what should i buy to become compatible with tamiya IRsystems. I know about DBU, and i dont know if elmod does that too, and rccommand has one. btw do they run off the heng long board? or do they come with their own...</p>

RCC went silent a while back, so you can forget that one. El-Mod is its own thing, and costs about the same as a Tamiya set up, but perhaps more work for a newbie to install. If you want to keep the HL electronics stick to the DBC.

DBU use HL board, ElMod system replaces the HL elactronics and RCCommand is out of buisness.
