The New Zealand Autogyro Association has its annual meeting in Dannevirke, in summer. Last year's midwinter fly-in from Whanganui was an extra.
This year Mr O'Leary is planning for the aircraft to fly together to an airstrip near Wai Inu beach on Saturday morning, have morning tea at his bach, and fly back to Whanganui for lunch.
On the Sunday morning they are to fly to Feilding airfield to join fixed-wing aircraft in a fly-in.
The rest of the time they can do as they please, and Mr O'Leary is hoping for good weather.
He said gyrocopters are "poor man's helicopters". Many are home built. They can have one or two seats, and be either open or enclosed.
They get annual inspections and are flown on a microlight licence. They can get up to 3000 metres high and fly for up to four hours.
Mr O'Leary built his own gyrocopter and mainly flies it around here. It can stay aloft for up to three hours and uses 15 to 20 litres of petrol per hour.
