Some people who own a model that uses the Crazybee F4 Pro FC like the Mobula7, Trashcan, RedDevil and Sailfly, recently have issues with Modes tab and OSD tab not loading in Betaflight Configurator. Here is how to fix it.
If the modes tab or OSD tab isn’t loading, or it freezes, or it gets stuck, this post is for you.
The Cause of the Problem
The Crazybee F4 Pro boards are loaded with beta version of Betaflight 4.0. The latest Betaflight Configurator (10.5.1 and after) might have made some changes causing certain things not to load correctly.
It’s very frustrating as some of these BNF models you buy today (Aug 2019) with the Crazybee boards are still shipped with this beta version of Betaflight 4.0 that was released back in Dec 2018.
The recommended solution is to update Betaflight firmware on your flight controller to the latest version. This should solve the issue. However you might lose your PID tune and other settings, so make a backup of it before proceeding.
Alternatively, if you want to avoid all the trouble going through reprogramming the board after flashing, simply install the older Betaflight Configurator 10.4.0. Download here.
Note that when you install a different version of configurator, it will “wipe out” the existing one. You’d have to install the latest version again if you installed an older version.
