  • Additional information


Sonda is a professional X8 coaxial octocopter designed and produced in Poland by HD Air Studio (All rights reserved). Four arms are made out of reinforced carbon fiber tubes. The folding arms mechanism is equipped with double locking system. Due to its foldable construction, Sonda is very convenient to transport.

The landing gear is mounted by thumbscrews, so it can be disassembled easily. The Sonda drone is equipped with the upper and lower mounting system (with the quick release connector) for additional accessories (for example a top and bottom mounted gimbal). Two passage channels, located in the center of a frame, connect the lower, center and upper frame. Electronics inside the platform are protected by an upper cover that can be quickly dismounted. ESCs are placed at the end of each arm between motors to ensure proper cooling and this gives more place in the center of the frame There are different types of power outputs connectors available to power external devices.

Sonda multirotor can be equipped with Pixhawk, DJI or other brands flight controllers. The drone can be equipped with FPV WDR camera, which allows BVLOS flights and helps a pilot define the flight direction. This platform is designed to mount different peripheral devices like for example, V-Map, Slantrange, Infinity MR-S2 gimbal, obstacle avoidance µPatch, uSharp and others.
