I've flown the fighterbird and the aerobird, but now I want to get into something even more interesting. Something wherein I can purchase my own 4 channel radio and servos, etc and go from there. Now, I'm leaning towards starting with a SLO-STICK or something of the sort, but the sales guys keep telling me things I don't completely understand *neophite that I am*. Can you help? What is the different between something like this (just the radio): http://www.ehobbies.com/rc-gws-t4a.html?AID=6265585&PID=1470972 ..and something like this (T-GWSRCS250B which comes with an electronic speed controller, 3 servos and a 600mah battery) http://www.hobbygenius.com/gws-4-channel-fm-radio,-3-mini-servos,-600mah-battery.html If I get the top one, do I need to buy the servos separately? Please remember I'm a noob, so any explanation would be very helpful!
