Actually, you can definitely replace this H with Yuneec. It is called a “Bind and Fly” package. If available, you can purchase a new hull sans the controller. A bit less expensive than a complete kit.
Note I said “purchase”. Yuneec will definitely help you with your purchase of a replacement airframe. The other option is to pay them for the cost of repairs, if salvageable.
This reply is not meant to be sarcastic, demeaning, or condescending. Rather, it is meant in the tone of “swallow your pride” and do right.
Others have claimed “hardware failure” and blame the manufacturer for mistakes similar to yours, even claiming a warranty replacement is due. Thank you for realizing the true cause. You do know the true and just resolution.
Good luck and hope you get back in the air real quick, learning from your experience.
