Just as phones receive software updates periodically to address patches and introduce new features, so does the Radinn jetboard. Firmware is the software that controls your jetpack, and from time to time you will be prompted through firmware updates. Running the latest software means your board will not only be more secure, but it will also perform better and be more reliable.
If there is a firmware update available, the app will automatically prompt you when you connect to the board. Just follow the instructions and you will be all set for an even better riding experience than before.
