Teams must build a nonpiloted flying vehicle that can accurately drop paint bombs on a target on the ground. Both teams need to go with radio-controlled vehicles, but that's where the similarities end. Three Revs a Minute are three trainee ministers (Get it? Revs?) who decide to build a working model airplane. Their opponents, The Mothers of Invention, go for a big blimp made of Mylar. The challenge begins at 3 a.m., since both teams want to avoid any wind.
