    The IC no. in pic 1 is scraped, to protect it from reverse engineering.
    Second one are relays, which switches the power to the motor and other high current devices.

    If you can give the part numbers from the integrated circuit at the top of that second picture, info about that may give a clue to what the one in the transmitter is.
    (The photo is not quite clear enough to read them accurately).
