This week, a trio of vicars called 3 Revs a Minute will face the Mothers of Invention building bombers. They will have to build a remote control flying machine that will drop a paint bomb onto a bullseye, also remotely controlled. Who ever gets their bomb to drop closest to the bullseye, with only 3 tries, is the winner.

3 Revs a Minute will build a conventional plane. As we remember from the 2nd series Glider episode, wing design will be the most crucial. A proper wing shape forces the air flowing over the top to move faster than it will across the bottom. This creates a differnece in air pressure and, voila, you have lift.

The Mothers will be building a blimp. They'll need a material that is light but will hold the helium very well, regular plastics won't do. The aerodynamics won't be much of a consideration but they will be more at the mercy of the wind if their steering fans don't work too well.
