Thanks all - again.

I've now read a lot, taken little in and will need to go through all of that again

I feel I really need to get my hands on something so Ican see it for myself (e.g., I can't see how an electric motorcircuit with a BEC works ... does the motor have an ESC connection still or does all the motor power then go through the RX?)

Lastly - is it normal for people to work out the motor/battery/prop themselves or pragmatically do people just use tools like motorcalc? I'd love to take a cheap combo like from hobbycity www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=4857but my plan shows I can have a max 8 inch prop and I'm still trying to work out how I find out what kind of power source to use.</p>

Thanks all and happy flying!
