Sure. But basically, all the subjects are getting cut off.

Gaza - can you make the subject line section in the forum topic list wider? It's cutting off the subject field really short.

Had another negative encounter, it's been a few years since the last one, just an uneducated ******, going on about drones being illegal yada yada yada.    :-/
Still that didn't spoil my flying time, had an absolute blast  ~~

DB that just means you have shed loads of props in the first place ;-)

Just had a thought, even with all the crashing I've done, I haven't bought any replacement props in over a year ~~

Multiwii PID tuning video

There is a good multiwii PID tuning video here;



You want to turn subtitles on unless you speak french though.

It';s actually very comprehensive - i wish I';d spotted this back when i was first starting with Multiwii boards!

So his PID for pitch and roll are P - 10.8, I - 0.010 and D - 33, that';s soo far off the defaults it makes me want to give it a go  :whistling:

teslahed

I think he bumps the I settings up a bit after he tuned the P values - just uses a low I setting to get the P in tune to start with.

But yeah, i';m impressed how high he got his P setting without feedback wobbles. I can get mine up to 6.5 from 4 and i thought that was quite good - 10.8 seems very high; i wonder how he manages it?

In terms of PID tuning i think the P value is most important - you can leave I and D on defaults for most aircraft. You just want to set P as high as possible without getting feedback oscillations - but it';s well worth playing with all the values.

Hello Mutirotor people,

I found this topic on rcgroups.

http://www.rcgroups.com/forums/showthread.php?t=1375728

That theory demonstrates an influence of D, completely opposite to this video.

That theory says:
Aerobatic flight: Decrease D
Gentle smooth flight: Increase D


This video says:
Lower D to get smoother reactions
Raise D to have more nervous reactions

And I Ask:

which one is right?


Thank for your attention!

Hugs,

JM
