A13 GST is an ergonomic design with a comfortable grip and precision gimbal control. The built-in integration of this new remote control system was developed specifically to allow single button control of multiple functions and to improve flight efficiency. Ground System APP is used to adjust the remote control parameters and custom button mode, so the DEMETER maintains the best-performing state.
Using a dual-frequency transmission system, with high-gain antenna, effectively enhancing the anti-jamming capability and picture quality.

Each sprayer uses a standard fan-shaped nozzle designed to reduced wear and tear to maintain an effective spray pattern also designed to be used on different crops to apply chemicals appropriate for the desired spray application program.
Flexibility to adjust the flow and atomization effect according to required operational needs by choosing either the efficient or strong spray mode. Each sprayer uses a standard fan-shaped nozzle designed to reduced wear and tear to maintain an effective spray pattern. The DEMETER is equipped with four spray nozzles designed to be used on different crops to apply chemicals appropriate for the desired spray application program.


The new spraying technology offers precise and well-distributed spraying controls, to achieve the maximum spray area with minimum chemical use.
The DEMETER E1 2166mm rotor blade span produces a powerful, consistent downwash allowing for complete chemical coverage deep into the crops.

A sonar altimeter is used to detect the terrain height so the helicopter can adjust to maintain the same distance from the plants to provide a uniform spray across all crops.


The Ground System APP is used to simplify the configuration of the spray route mapping. Use the drag and drop feature to mark the designated area for spray application. The APP calculates an efficient spray route which is displayed. The spray route can easily be adjusted using the APP. If the amount of liquid, to be sprayed, is entered the Ground System will automatically calculate any remaining parameters, thus conveniently improving the efficiency of route mapping and spray application.
When flying and turning a corner, it'll close Spraying; when moving forward in route, it'll re-start and make sure no Spraying at the same place. If there are buildings or objects, setting obstacle mark to make DEMETER keep away this area spraying.

DEMETER E1 incorporates an intelligent route interruption resume function. The AP2 saves the last chemical spray-location. This function allows the DEMETER to return to the previous spray location to continue the programmed spray path. This particular feature ensures reliable deployment of chemicals to provide efficient plant protection.


Offer two flight mode (Nose heading to the front or Nose heading to the back) allow to keep the most efficient spraying to save the chemical and reduce the ground pollution.

The Ground Station APP simplifies route mapping to automate flight. A complex mission is quickly programmed to achieve full automation of chemical spraying, applying a uniform application on the crop or farmland. The system is designed to apply the maximum application of chemical in the shortest time to increase efficiency for better results to ensure maximum crop yield.
