Here you can see the receiver mount which has been made, to cover up the space between the two frame halves, a triangular piece of wood has been inserted in-between, and styrene sheets glued on top. The triangular wood piece in the picture is then glued onto it, along with the Velcro tape that will hold the receiver in place.

The receiver used for the prototype is a 7-channel Futaba FM receiver on the 75 mHz band (the standard surface frequency denoted by the FCC).
