THERE will be a buzz in the air when the Suncoast Model Flyers hold their Model Air Show at Coolum on Sunday.
Events co-ordinator Roy Salmon said a big crowd was expected at their field on Quanda Rd.
"Scale model aircraft ranging in size from 750mm (35 inches) up to 3400mm (11 foot) wingspans will be taking part in demonstration flights, including aerobatic manoeuvres," Mr Salmon 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 WW1 fighters to WW2 British Spitfires and Hurricanes, US Mustangs and Kittyhawks, a scale model B17 Flying Fortress and large scale choppers.
A special drawcard will be the appearance of the Coast's own Chris Callow, currently four-time world champion of F3D radio controlled air racing.
This particular flying event has been hailed as the "Formula One of plane racing".
During the races, spread over four days around a triangular course, fleets of model aircraft reach speeds of up to 360kmh.
Mr Callow will be flying the plane he flew to success at the 2011 world titles.
The Model Air Show will run from 9.30am-2.30pm.
Food and drink stalls will be operating.
Entry is $5 for adults and $2 for children aged 4-14.
Parking is free.
