Advice for beginner on transmitters/receivers
 

Hi guys, been lurking for a while. And want to start getting into the world of RC :)

My friend recently made a Cable Cam prototype in his garage, he stripped down a cheap £15 RC car and used the internals of that and made a very decent cable cam, however one of the main flaws being the RC car was using infrared, so it didnt really work outside of his garage.

He wants to take it up a notch and has come to me for advice but I am way out of my depth, but it is something I would love to get to know more about and I am pleased he has asked for a parter to collaborate with.

I was thinking of using an Arduino board to power the motors and receiver, but want some advice on transmitters and receivers please. We are looking for something that will work around 100m away and about 15m up in the air. Would this be possible using 2.4ghz? Or would I need to use something more/less powerful? I am also wondering whether we would require antenna's etc?

I know this is a broad subject but any pointers in the right direction would be very much appreciated.

Thanks everyone in advance.
