Electrifly Cub, slow stick, Parkzone Cub, hobbico skypilot or ventura, or GWS Beaver or estarter. All these planes are great flyers and can be used for mild aerobatics when the time comes. Most are made of foam so they are inexpensive and have replacement parts. Personal favs of mine are the Ventura and Cub. I've flown both and the ventura is nice cause you can get it RTF for around $100. It's a great trainer and glides nice. Also the cub is excellent too. Very forgiving if mistakes are made and has good performance right out of the box.
