आरजी106 प्रो/मैक्स ड्रोन के लिए रिमोट कंट्रोलर

"When I received the drone controller, I turned it on immediately, but it did not respond at all. I purchased the controller because my existing one was consuming the battery too quickly and I wanted to replace it. However, when I switched it on, there was no message displayed on the screen. Even when I charged it with a 5V, 1A charger, there was no change in the screen display. I suspect that the built-in battery in the controller is completely discharged. If you could provide me with the contact information of the person/company who sent the item, I can send pictures as well. My request is (1) to exchange the controller. If you require any related photos, I can send them to this email. I would appreciate a prompt response. Thank you."
