A major Typhoon H Plus upgrade has been released and is available for OTA. It is important to do this upgrade ASAP.
It upgrades all components of the various systems including the ST16S Android.
Warning: Have the controller and craft batteries fully charged. Make sure you have a good internet connection and its password handy. Do not attempt this without reading the procedure in the manual (page 20). It will take some time, be patient and once started do not disturb the downloads.
