    Hello guys, recently i asked a lot of questions in forum regarding some PCB designs. The ideia behind all this, was to make a Remote Controlled RF Car toy, it's a very simple design, and with my current knowledge i believe it will work. But i would appreciate, if someone could take a look, and tell me if my design or my theory is correct. Some of you may already have seen these next images.

    The following PCB's, Diagram and data charts are all related to the RC Car:

    PS: Some connections were larger, some pads too, just for the purpose of facilitating the pcb manufacturing process.

    The batteries i intend to use is 7.5v for the receiver and 9v for the transmitter. Also the motor data chart goes below:

    So there a few questions to initiate the subject i would like to ask:
    1) Is it good to put 0.1uF ceramic capacitors in the pins that are linked to the jumpers ? Because the airwires will also work as an antenna, wont it ?
    2) Is it good to attach some 0.1uF ceramic capacitors into the motors ? To reduce the electronic noise ?
    3) What would you do it differently on the positioning of the devices in the board ? Is there a better way ?
    4) By all means, it should work right ? My by knowledge there is no major flaw in this. But just to add, my knowledge is very short on this.

    Thanks to everyone who already answered my other threads, it has helped a lot, all the guys and this forum, they have been just awesome to me, i don't remember some names right now, but thanks a lot, it meant the world for me.

    PS: I attached the eagle files, if anyone wanna take a closer look.
