Gliders
I still have my aerobird and I still fly it occasionally. Speaking of gliders, I'm not sure they make good trainers. A purpose built glider has a long wingspan and a very long glide slope. You actually need quite a bit of room to get a glider back on the ground. You might also consider the GWS E-trainer, they are inexpensive(about 40$ for plane, motor and hardware). This plane has rudder, elevator and ailerons. By the way, you got the electra-jet for a very good price.
