DIY HOTAS Gamepad Frsky M7

thingiverse

After the 40 and 45 HOTAS I wanted some more changes so I designed a third version. The biggest changes is the stick gimbals which are new ones (instead of old re-used). The performance and resolution will be much better due to ball bearings and hall sensors. The controller is powered by a Leobodnar BU0836. The two sticks have high resolution hall sensors. Eight push buttons and two dials as well as a 4x4 keypad. On the front is two 4-pos slide switches, a hat switch and a two axis thumb joystick.
