LEGO LEGO® Power Functions IR Receiver 8884

This unit is brilliant !! It's not just a reciever, but also a twin controller unit. It has 2 separate subchannels for each of the 4 main channels. This way it will control 2 motors or 1 motor and lights on a train, or any two powerfunction units. As a "train-o-holic" this unit along with the other controls is a MUST for powering and controlling modern LEGO IR trains. I wish that LEGO would make a SET with the necessary items for powering trains: 8884 IR reciever 8879 IR speed remote control 8870 lights 88002 train motor 88000 battery box (or alternately, 8878 rechargable battery box and 8887 charger) And then give us a reasonable rebate on the whole deal, since we already have bought a train. {;o)
