You check out the link below for a mostly complete system that includes the plane, engine, and radio sytem. It sells for $380.00.
Here is another one for $280.00. Hope this helps ot at least gives an idea of what you need for a minimum basic setup. You will still need fuel, props, a starter, glow plug driver, battery to run the starter and driver and a fuel pump. Add $10.00 on to this to get a tool box from Wallmart to use as a field box. These are the extras that are needed but most new flyers don't know about it. [8D]
