This is the top air frame for the Yuneec Typhoon H with the GPS components. The GPS is what keeps the Typhoon H stable in flight. This item is recommended if you know that the GPS does not work on your Typhoon H and if you know how to and are capable of swapping out the GPS unit. Opening on and working on the Typhoon H is difficult. Terrestrial Imaging is an authorized Yuneec repair center and can repair your drone for you. If you have any questions give a call. Thanks for looking!
