know I bought a typhoon h when it first came out it flew great and I saw on yuneec web site they had new firm ware to install. So I ereased my flight data like they said and tried to install the new firm ware when it got to the camera or there abouts it just stopped and wouldn't finish the install so its been setting for the last three years without any flight data. Has anyone else had this problem and been able to fix it. It won't fly without it
