The Wellington Model Aeroplane Club flies its model aircraft on the Seddon Rifle Range in Trentham, where the Army controls the range and the club shares the field with the rifle users. Members fly radio-controlled planes, gliders (slope, thermal soaring and hand launch), helicopters and multirotors, with a small group of free flight and control-line flyers. Competitions in aerobatics, scale, pylon and vintage classes are held through the year. Flying usually starts on Sunday mornings, from about 9am, and the field stays in use into the evening in summer. Visitors are welcome. The site has a red flag rule: when a red flag flies at the entrance or the gate is shut, nobody enters. A webcam on the range shows whether anyone is flying, and the weather decides whether the field is in use.
Indoor flying takes place in halls for smaller electric models. Pilots pay $10 to cover the hall rent, and spectators are free. The next indoor session at Riverstone Recreational Hall in Whirinaki was set for Friday 23 October 2026, at 7pm. The club's monthly meeting is held on the last Wednesday of each month, except November and December, at Belmont Memorial Hall in Lower Hutt. Meetings focus on a theme, a guest speaker or a workshop.
