Ok. So I'm going to build a quadcopter that is controlled using a radio transmitter/receiver pair
The one I'm looking at is something like this
http://www.ebay.com.au/itm/433Mhz-RF-transmitter-and-receiver-link-kit-for-Arduino-ARM-MC-U-voltage-3v-12v-/201160180125?pt=LH_DefaultDomain_15&hash=item2ed614c19d&_uhb=1
The problem is that I've never done anything with radio control before. Communication between the remote/receiver seems relatively straightforward. The problem is how does the antenna work, and where do I attach it? I've searched the internet, but it almost seems like the question is so simple it doesn't need answering.
I feel a bit stupid asking this
But thanks in advance
