David Hopper - W4STJ

Retired from the commercial two-way radio business and now still tinker around with other project plus helping out occasionally at the Georgia Public Safety Training Center with their crash tests. Data retrieved from post crash analysis is used in their crash reconstruction courses. See Truman Boyle's YouTube channel for more crashes.

Videos here are from some of those crashes plus odds and ends of all sorts. I'm no professional but I do have fun so enjoy!
