Some of the 3 and 4 channel park fliers can fly very slow. Don't dismiss the 3 channel ones. I learned on a 3 channel plane (with a 4 channel radio), it's surprising what you can do with rudder and elevator. I don't have either, but the GWS Estarter and Slow Stick are supposed to be decent. Check out the electric forums and the user reviews for more ideas. Add a basic 4 channel radio with a micro flight pack, a couple batteries, ESC, basic charger, (and ?... I probably missed a few things) and you're good to go.
