印度采购需求：无人机、遥控车、益智玩具、积木、游戏桌、国际象棋

I'm looking to explore options for drones that could meet various applications within our work. Ideally, I need models that balance performance and reliability, with features that cater to both aerial photography and potentially some payload delivery capabilities. It's essential that these drones are user-friendly and compatible with various software solutions for mapping and navigation. Additionally, I'm interested in understanding the availability of spare parts and support services you offer. Can you provide details on the pricing, lead times, and any bulk order discounts? If you have product catalogs or specifications, please share those as well. Your insights into the latest technologies or innovations in the drone sector would be greatly appreciated, as we're eager to stay ahead in our operations.
