MODEL plane enthusiasts' hearts will soar at Calvert this Valentine's Day, when a four-day air invitational takes wing.
Competitors from across Australia and from overseas will flock to the Spektrum Gratton Air Invitational to vie for world championship titles, organiser Robert Knox said.
The exhilarating event would be great for both long-time enthusiasts and fans new to the sport, Mr Knox said.
"One event is pylon racing on a triangular course with up to six planes at a time; it's like a mini Red Bull Air Race," he said.
"There will also be a scale model contest, and these guys spend months building accurate models and are judged on the appearance and on flying them to scale."
Mr Knox said the invitational was a rare opportunity for Ipswich enthusiasts to witness such a high level of competition.
Daily lunchtime flying routine displays will allow visitors to watch model aircraft be put to the test.
There will also be radio-controlled buggies and giant models of armoured vehicles.
The Air Invitational will run from Thursday to Sunday at Gratton Field, Bourkes Rd West, Calvert, past Rosewood.
Entry is free and daily programs will run from 9am-5pm.
