re "I see lots of TPWR increases correlated with sudden, dramatic drops in throttle signal. Perhaps there's lots of electrical noise when the motor is being throttled down."
Comparing 2 intervals, 75 - 230 sec and 230 sec -340 sec, there is higher throttle overall in 75-230s, with more ups and downs. The ups are higher, but apart from one down around 90s, the downs are not really different to 230-340 interval (ok the down at 160s is a little bigger). The standout thing is that 75-230 has lower RSNR, yet the signal indicators are not showing much. The signal has little change, so for the signal-to-noise ratio to fall, the noise must be more. I agree with you, I suspect the throttle, but I do not know whether its turn up, turn down, or average throttle that is responsible.
