welchcp - check out the "sticky" thread about MinnFlyer & RCKen joining forces. Both are fantastic sources for the kind of info for which you're looking. The 2nd post (MinnFlyer) has a link to getting airborne.

If you browse the forums / sub-forums here at RCU you'll see the general segregation of topics. The biggie is propulsion: electric, glow (2 & 4 stroke), gas (primarily big toys), turbines. Then there's type of interest - sport, pylon racing, scale, warbirds, 3-D, pattern, soaring, the list goes on and on - limited only by your imagination.

Good luck while you sample this addictive hobby ...

Oh yea - get hooked up with a local AMA club. Training is a good thing. The simulators will give you awareness and familiarity with the transmitter (aka Tx) controls and how the planes behave. Different from actually playing at the field.
