THERE will be a noticeable buzz in the air when the Suncost Model Flyers hold their Model Air Show this Sunday.
Events co-ordinator Roy Salmon said big crowds were expected at their Coolum field on Quanda Rd.
Previous events have proved popular with the locals.
"Scale model aircraft ranging in size from 750mm (35 inches) up to 3400mm (11 feet) wingspans will be taking part in demonstration flights, including aerobatic manoeuvres," he said.
"As well we will be featuring large scale model helicopters, both civilian and military types and we should have real jet engine scale models operating."
Many scale model aircraft will be flying and on display, ranging from British Spitfires and Hurricanes, US Mustangs and Kittyhawks to a scale model B17 Flying Fortress.
There will also be no-charge opportunity to test flying skills on the electronic simulator.
The Model Air Show will run 9.30am-2.30pm with gate opening at 9am. Food and drink stalls will be operating throughout the day.
Entry is $5 per adult, $2 per child aged 4-14. Parking is free.
