1-10 Scale RC Boat Radar

This is my first ever built from scratch. Is very elemental, but works for what I was trying to accomplish. I made this for my Thunder Tiger Atlantic Motor Yacht, is an electric rc boat, but I am sure you can fit it in any boat of similar size (25" to 35"). Here is a video of the boat before I made the radar.
