Janet:
If you are a rank amateur at this, you might be well advised to get an airplane set that is a proven electric for your first one.
Check Dare Design,
http://www.darehobby.com/ they are largely electric, and the instructions will lead you through to a successful flier.
You could also go to any one of several others for a similar kit or design.
If you are willing to go larger, the "ElectriCub" is a good flier, and if you decide a six-foot wing span is OK, the Goldberg "Electra" is a nice plane.
Regardless, have fun with whatever you build.
Bill.
