More than 100 radio-controlled model aircraft, from World War I biplanes to screaming jets, will be in action over Awatoto this weekend - with half the gate takings going to the Red Cross Christchurch earthquake appeal.
Hawke's Bay Radio Flyers is hosting the annual Warbirds Over Awatoto event on Saturday and Sunday, with club member Jeff Clarkson saying members were conscious of the need to assist the appeal.
Christchurch-based radio flyers had often travelled up for the event in the past. "Our thoughts are with Christchurch," Mr Clarkson said.
About 50 pilots are expected to put their models through their spectacular paces, with Waikato-based aerobatic champion Frazer Briggs set to again show off his skills.
There would be a diversity of aircraft from the early biplanes through to jets, Mr Clarkson said.
The forecast for some rain to pass through the region was unlikely to keep the aircraft ground-bound, he said. "They can still go up, as long as it is not too heavy."
Pilots of some biplane models did have to keep an eye on the wind though.
The forecast is for possible rain on Saturday and a temperature of 22C and some northwesterlies.
The Awatoto airfield, just off Waitangi Rd, behind the fertiliser works, will open from 9am to 4pm on both days, with a $5 charge for cars, regardless of how many people they carry.
