The Navi RX is like a standard NAVI except it offers motor redundancy. However, the trade-off is reduced flight time.
The eight-motor Navi RX with RTK GPS starts at NZD $33,300 (includes the ground control station, battery, battery charging kit, and transport case).
Payloads and shipping are additional.
Aeronavics drones are generally larger, more robust, offer better performance, and are more flexible in terms of behaviour and ability to integrate payloads. They are able to do things that other drones cannot do, but at the same time, a higher degree of knowledge and training is required to operate them effectively.
