Have had this issue for a while, but never found a solution:
Everytime i press mention buttons while in the air in a SIM battle my gear and flaps all deploy and extend.
Hella annoying to say the least to have them ripped off each time…
Have gone trough every single keybind to no help, it keeps happening.
Use Winwing F16EX Hotas, but doubt this is a hardware issue, Gaijin is the suspect here
