With a top speed of 58 MPH this Scratch Built Cargo Dropper RC Plane that ExperimentalAirlines built is no slouch. There is a video camera in the cargo bay so you can watch the cargo drop, there is also a camera mounted on the cargo so you can watch the cargo falling from the plane. Nice to see that the plane is primarily built from cheap foamboard and looks like it would hold up quite well.
