I understand some electric car makers are putting low speed beepers like on garbage trucks when they back up.
so is this going to be a "BEEPING Spad"?
I have built and flow a handfull of spads and they have a couple of fine trainers, ie. the Spadet and Debonaire. I just gave the guy that mows the most at our field a 40 Buhor wing on a gutter spout fuse almost ready to fly just cuz he needed a second bird[8D]
