Pilots donated their time and aircrafts to put a smile on the faces of children and teenagers affected by life-changing illnesses or adverse circumstances.

Bendigo Flying Club president Neville Boyle said it was a great community event.

"We have kids from a whole lot of different organisations including St Lukes, Scope Victoria and HeartKids," he said.

"The majority of them are from Bendigo but there are some from Swan Hill and a few from Melbourne-based organisations.

"We're not just flying the kids but also the kids families as well."

The runway at the Bendigo Airport was abuzz with activity on Sunday with about nine planes participating in the event.

Mr Boyle said some pilots had even hired planes to enable them to take part in the day.

"We've also got face-painting and an amateur radio group and we put on a meal for everyone as well," he said.

Mr Boyle said the event took a lot of work to coordinate but was incredibly rewarding.

"Funflight is a national event that will cater for 1500 kids this year," he said.

Ryan Murray, 7, was one of the lucky participants.

"It was good," he said.

Cayden Burns, 4, also enjoyed a flight over Bendigo with his sister Charli, 7, and their dad Glen.

Cayden proudly showed off his scar from major heart surgery when he was just five days old.

"Events like this are just fantastic, especially because they include the whole family," Mr Burns said.

"Thanks to all the volunteers."
