Andrew Tridgell 1727d9a5be Filter: protect against extremely low notch filter frequencies ... an incorrectly configured ESC telemetry source can lead to a notch running at very low frequencies. A simple example is a lua script like this: function update() esc_telem:update_rpm(12, 0, 0) return update, 10 end return update() where motor 12 is unused. with that script in place we get a 1.0078 Hz filter which leads to massive phase lag and a crashed aircraft this is a safety protection. We should also try to find out why the INS_HNTCH_FREQ lower limit is not working		2024-01-07 10:59:28 +11:00
