DJI Inspire 1 and Walkera Voyager 3 are two of the top names that always come up when it comes to aerial photography drones. DJI Inspire 1 was launched in Korea January this year and is well-known among drone users.



DJI Inspire 1 quadcopter features a unique design and integrated 4K camera that provides 360-degree view. Its retractable arm system with propeller motors acts as landing gear by lowering and lifting the arms. The arms lift up at takeoff to ensure safe flight and provides the camera with an unobstructed view.

DJI Inspire 1 is priced at USD2899 (Single controller mode), equivalent to KRW3.5 million in Korea.



Launched after DJI Inspire 1, Walkera Voyager 3 is top of the line all-in-one prosumer drone from Walkera. Because its appearance resembles that of Inspire 1, Voyager 3 has often been called Inspire’s copy.

Voyager 3 also has integrated camera capable of 360-degree view and three arm landing gear. The camera moves downwards as the landing gear retracts in order to prevent the aircraft from being exposed during filming.



Voyager 3 is priced at USD2199 (4K camera version), USD700 less than Inspire 1. Currently, Voyager 3 is not officially distributed in Korea. Although pre-orders can be placed through some RC dealers, these are not imported through official channels and therefore have not received radio frequency authorization. By law, products which have not received due authorization cannot be sold by retailers to consumers. Also, products purchased individually through overseas sales channels are not allowed to be sold secondhand to other consumers. This is extremely important to take into account when buying Voyager 3 in Korea.



Both Voyager 3 and Inspire 1 are equipped with powerful brushless motor and are capable of stable flight using the GPS-guided system. Whereas Inspire 1 uses geolocation from GPS satellites, Voyager 3 utilizes GLONASS dual-navigation which enables access to larger number of satellites, providing more accurate location data. GLONASS was launched by the former Soviet Union during the Cold War era to counter US GPS satellites. First launched in 1982, a total of 24 satellites were scheduled to be launched. But due to the economic situation following the collapse of the Soviet Union, only 8 GLONASS satellites are in operation today.

Unlike GPS, GLONASS uses the FDM (Frequency-Division Multiplexing) scheme, meaning each signal is assigned a different frequency. In addition, the P-code used only for military purpose in the GPS system, is open to civilian access. The GPS-GLONASS dual-navigation system enables a more precise and stable flight. Although access to larger number of satellites is clearly an advantage, the GLONASS effect cannot really be felt during actual flight. Details will be provided in the upcoming performance test between the two models.



The main reason why drones are becoming so popular is because of their ability to take professional quality aerial photography. Both Inspire 1 and Voyager 3 feature 3D gimbal and 4K cameras. The two models also have very similar camera module design.

When reviewing the product specification list for drones, consumers often come across the terms ’2D gimbal’ or ’3D gimbal’. Gimbal is a pivoted support that allows the rotation of an object about a single axis and keeps the gyroscopes upright.
