even at low P gains of around 40, P spikes back sharply before set point had been reached. 400 degrees per second when you asked for 800. P term swings the other way at half the desired rate. Maybe lostcontrol can open the log and show you with a screenshot what we mean.ĮDIT: Forget all that above I looked at your second picture and it seems your correct. I forgot to look at the log last night and I don't have access to the BB again at work. You can manually play with the scaling in the graph set up menu to see what I'm talking about. Like I said in my previous post move your cursor to the peak of the Gyro and compare the numbers in the legend to the right to the degree per second of the RC command. If they are scaled differently the magnitude of the graph may not represent the same Degree per second visually on each line. The gyro graph and the RC command graph are two completely different graphs scaled differently to fit on the same screen. The values are clearly shown on the snapshots - right hand side or you are saying the values aren't correct ? Fortunately, that happened when I was flying low. No f*** clue what happens there but I think the RF situation at that place is special. This weird place is a soccer field with artificial turf, surrounded by metallic fences. I fly ~500m away, in woods, next to concrete buildings with those quads, never had a single failsafe otherwise. Both time with a different quad, with several months interval in between and at the exact same place And with something like 20-30 meters between me and the quads when they failed. I had 2 similar crashes caused by what I think is a short failsafe. 4 packs later and it didn't happen again.
IANALYZER LITE FULL
Suddenly I regained full control and finished my pack to see if I could replicate the issue. I have a stage1 FS setup with everything default, but I couldn't have been more than 100 feet away from my quad in an open field when this happened. I was flying my Darkside200/BFF3/BF3.2 and suddenly had no control over anything, yet I was still coasting with my last held settings. I came back from flying just 15 minutes ago I had something similar, but different.
IANALYZER LITE FULL SIZE
(i don't know if i've embedded the full size image in the intended fashion, but that green line is the good thing. your life is now twice as good as it used to be. anyway - i assure you - it is now time to celebrate. I ought to get through some other possibilities tomorrow. god help me if i ever have to explain what life with difficulty is to some of the people on this forum again. Let's keep hoping on that heart attack, huh. unless you suffer from poverty computer environments. you filter an "impulse" (first sample = 1.0, rest of samples = 0) and then the fourier analysis will give you a lovely mag and phase response. I still have to chart the 12dB 0dfs and see how they do (that 6dB one was useless tho).įyi: the method i am using is fourier analysis of course.
occasionally it just "runs out of memory" or something). it refuses to process i*i+r*r it crashes unless i reduce it to i*i. it's one of those stupid bugs that you get with this old stuff (it won't compute the mag/"leg" with the real component, only the imag.
IANALYZER LITE SOFTWARE
Unfortunately my software environment has a bug and my nice graphics will only show the phase response, not the magnitude. I've used the simper svar extensively in audio (it has a nice steep rolloff at nyquist) and can assure you it is sufficiently steep and cascades nicely. I have found a preferable solution for your lowpass filters - the "andrew simper trapezoidally integrated state variable" 12 dB lowpass features *half* yes *half* the group delay of a biquad 12dB lowpass. Just dropping in late for a quick word in case i have a heart attack in the night,
