I’m experiencing a very strange thing in Auto throttle modes. The demanded acceleration output from TECS is oscillating between -.6 and +.6 and this causing a very bad throttle pulsing. The interesting thing is is that I see it on three different planes (different sizes, motor configurations), but I don’t see where is the source of this oscillation. Airspeed is solid, throttle RCin does not change. Any ideas before I start poking around in TECS tuning ? (All three planes has default TECS settings, beside the TRIM_)
Setting throttle slew only mask (more or less) the spikes in motor output. So it is not a solution.
