Here's the quick build blog for my F16 foamboard RC plane, I posted the maiden video last week. Dead cheap and easy to build in a couple of hours. One A1 foamboard sheet, or 2 x A2 sheets. Cost a fiver at most. 2 x 2g servos, BR1806 motor, 10A esc and I used FS2A rx. My free plans are linked in video description. 2 plan versions, this one and a 20% scaled up plan, which should be a bit slower and easier to fly. Plus there's a full list of parts.
