One way of attracting a crowd at shows like AOPA Summit is to have a clever gadget, and Anthony Chan definitely has one in his wirelessly controlled aircraft tug. Chan was putting the tug through its paces on the exhibit floor in Fort Worth this week and drawing plenty of interest. Unlike most tugs, which use rubber-tired wheels for traction, the AC Air Technology tug has a miniature tank tread system driven by a pair of powerful electric motors powered by a lithium-ion battery capable of multiple tows.
