CMAC has one of the best flat-field flying sites in New Zealand. There is a CAA approved permanent danger zone that is 2km in diameter and to a height of 950ft (289m) above ground level. Flying is possible in all wind directions and seeking and riding thermals can be safely done over this large area.
A wide variety of soaring is carried out, from 2m foam plastic Radian flying to 7m scale aero-tow models. There is an emphasis on competition soaring, with a range of monthly NDCs (National Decentralised Competitions) being the main focus of the clubs soaring activities (although there is regular sport and practice soaring by members and the occasional inter-club or national event).
Traditionally, gliders were launched by hand tow, electric winch or bungee. Although there are regular competitions that require these types of launch methods, more and more competitions (and sports flying) are by electric motor launch. In most competitions involving this type of launch, the motor run is restricted by an on-board time / altitude switch that disables the motor at a pre-set height or run-time (an ALES device). Other methods of launch can be by hand, by aero-tow or (at certain sites around Canterbury) from the top of a hill or cliff (slope soaring).
Over the years, CMAC has produced a number of soaring pilots that have successfully competed on the world stage. Also, CMAC has recently become one of the most successful competitive soaring clubs in New Zealand, both at national competition level and in ND competitions.
Thermal soaring is a challenging and satisfying way to fly radio control models. Seeking out and riding rising air to maximum heights is a constant joy for many, and there are few better places to do this that at the CMAC Willows site
