bought a Dji inspire, but have been grounded since acquiring it, very frustrating. RC will not connect to iPad 2 mini or any other platform. Have tried all other ports and still no connection . RC connects to AC and is fully operational but no camera function in app. I have ordered a new usb hub to change it out.... Hopefully this rectifies my dramas. Will update tomorrow after receiving parts. Does anyone know the exact size of the driver I need to remove hub screws ? Cheers
