It depends, do you want lights or to run a 2nd motor slaved to the first? You
wouldn't run over the 1 A limit, since you would have (C 25 Ohms/motor, 25/2=13
ohms circuit, 9/13=less than 1 amp). You should NOT try to run 3 motors
connected to the same reciever, at least, not if it is a 1A reciever.
The only way that I can see to manage to get lights and be able to slave the
motors would involve trying to get a 2nd connection inside the motor, at the
other end. (Idea for Lego, but not so easy for the rest of us!)
