DIY HOTAS Gamepad Frsky M7

thingiverse

After the 40 and 45 HOTAS, I wanted some additional modifications so I created a third version. The most significant changes are new stick gimbals (instead of re-used old ones). The performance and resolution will be greatly improved due to ball bearings and hall sensors. The controller is powered by a Leobodnar BU0836. Each stick features high-resolution hall sensors. Eight push buttons, two dials, and a 4x4 keypad are also included. On the front, there are two 4-pos slide switches, a hat switch, and a two-axis thumb joystick.
