Yes, that is why I was thinking if it's even possible to fix. When I spotted this behavior I suddenly realized the problem with auto leveling that MultiWii and Naza have when flying fast. They both do not level out fast, instead they keep flying and level out very slowly. I think that is the same problem...

I wonder if there is a gimbal controller that does not feature this effect. Naza gimbal sucks, MultiWii works well, especially 2.1 version when servo refresh rate can be set higher. But it looks like it can only be used for really easy flying... oh well.

Could use a second multiwii with different PIDS etc for the gimbal. Tune to how you like.

Or fly slower

anyone with a blackvortex board managed to get the integrated GPS to work?
Any idea about that?

I actually use Naza as FC and MWC as Gimbal controller because Naza flies well but gimbal control sucks.

For the MWC Gimbal there are no PID settings, just P setting for roll and pitch. Too little -> it lags, too much -> too sensitive.

I think I just have to fly slow.

I do not have any filters yet and I only use one LiPo for everything so I know I can make some improvements there.
But I just don't understand why it didn't recover from the fail safe when I basically stood next to the copter and didn't get any more response.
It seemed like the program has crashed and needed a reboot.

Can the FPV TX cause that? Maybe through interference through the common wires?

Well, I personally have never experienced the problem because I have not flown outside of LOS however, I have read numerous horror stories in the Video Piloting Forum Seems 1.2Ghz and 2.4Ghz don't mix very well and a bypass filter is required. This maybe why you are unable to reproduce the problem during ground testing.

1.2 Ghz equipment is going to have a second harmonic at 2.4 Ghz. Perfect !
In close proximity the two systems will have problems.

How to test MultiWii failsafe in action? I don't want to crash my lovely quad. Fly close to the ground with rope attached, LOL?

What I do is remove the props, arm the copter, spin the motors at about 1/3 or less throttle, then shut the power off on the transmitter. As for auto-landing etc, that is not working to the degree that it should so I don't worry about that. My only concerns are fly-aways.

I'm having the same behaviour as you, with my ecilop and naze32. After some time the gimbal goes left and back after some fast flight.

I will try to use the APM gimbal feature to see if there is diference.

It was just a dead calm day out there wasn't it. Very nice as usual Markus. Nice to see another side to your flying. I always enjoy watching your clips.
