One of the best plug and play options is the Tamiya. It does all of what you ask without a bunch of wierd science. Dollar for Dollar hard to beat, but I sure keep trying!!!!!!

The sound module will run with any RX. The DBC is designed to work with the HL electronics, so that is what it does very well. THe DBC2 allows you to use a regular radio with the Heng Long electronics, and then of course has all the IR fighting capability of a Tamiya.
