I replaced hall effect sticks on my sn30 sf30 pro
I bought these hall effect modules on AliExpress for experimenting purpose and it turns out to be working beautifully. here's the video for the demonstration https://imgur.com/a/xwaFxOD
after you finished installing the sticks, you don't have to do any calibration what so ever because the controller itself is self calibrated via software. this is actually a big time safer.
Oh forgot to mention that you should search for the Version 3 of these joysticks (eg. Orange Hall effect V3) since v3 is the latest version without the jitterness. so ask the seller for the newest batch before buying those sticks.
