Here's a foot-operated launch controller I made that I nicknamed the Shoebox. It's for launching RC models while keeping both hands on the transmitter. It's a standard circuit with a 11.1 lipo hand down by velcro to the inside floor. I probably should paint it. Maybe black with red hotrod flames.... BTW, I made this last summer. I was on vacation and wanted to go up to Mom's and work on the Studebakers. However her house was suffering from a bad case of the bats. So I stayed in Omaha and stayed busy doing goofy projects like this out of frustration.
