Sir David Jason and Jay Blades are at the Midlands Air Festival at Ragley Hall, Coventry. This is an event with plenty of air displays that attracts enthusiasts of all kinds.

Their first guest is Chris, an avid 'hacky racer'. Hacky racing involves making an improvised race vehicle on a strict budget, and Chris is partnered up with expert mechanic Allan Robinson to help replace his race car's alternator with a motor.

Meanwhile, pensioner and model cart maker Dave brings along some of his incredible homemade cart models. Longing to learn the art of gold leafing, he's partnered up with professional signwriter Kerri Williams, who is delighted to help teach Dave.

Jay heads into the festival to meet with a group of hot-air balloonists who are so passionate that they make their own balloons. Show less
