After installing the latest MP firmware (2.3) for my octo.
Im getting a strange twitching when i spin up the motors on the ground as seen in the video.
I have tried changing the RATE P and STAB P to no avail.
It however still flies, fairly stable, but still with that strange effect.
It seems to be a bug concerning Rate D.
2.3.1 should resolve this, I hope.
Its nothing that could cause a fatal crash though?
maybe the same as this video shows http://www.youtube.com/watch?v=5NJjCT9Oc0g
easy to fly but twitches. but dont listen to me, liftoff is your own responsibility.
Liftoff isnt a problem, just gotta do it quick and carefully ;)
I wouldn't fly that expensive looking octo with that twitch going on.
The twitch is more pronounced because its not rigidly attached to the landing gear, but i think I agree with you...
