I do not think I could tell you the problem. I apologize for that. My problem is that the drone cuts off the signal after a certain distance. How can I fix this signal breakup
As we suggested it is likely a fault with your receiver or radio… the way to fix it is to replace the faulty antenna, or the faulty device (either your receiver or radio)
The drone is crashing like this.
The flag is not circling. The drone is on its own.
What reciever are you flying?
