PostSubject: CANNER FPV - better float   Mon Dec 11, 2017 1:28 pm

Finally using an ARM switch now. Smile Also enabled Betaflight Antigravity properly, didn't realise Betaflight's default 1 means it is off.
PIDs are still a bit off, but this will surely get better when I can go out again after the weather improves.
Till now I had VBAT_compensation enabled, an option that adjusts the PIDs according to the remaining batteryvoltage.
That's why I never got a good feeling for the changes I made to the PIDs myself.
The VBAT comp makes the quad fly fine one moment, then shit after the next turn, and then fine after the next again.
The KISSFC flew better after enabeling it, so since then I automatically enabled it on all my quads all the time.
Only turned it off after the very last flight, so have not tried yet, can't wait to go out and get back to tuning.

Does look very smooth now canner m8,it could be down to your muscle memory getting
better or the tuning,a but of both I think.

Gonna have to research this anti-gravity setting and learn more about it.

All that practice helped a lot ofcourse, but using a switch to arm makes a big difference.
Before the quad would dip at low throttle, or worse the props stopping and powering up mid air.
This would cause some erattic behaviour making the quad tumble till props spin hard enough to gain control again.
With an arm-switch the props keep spinning when throttle goes to 0, keeping the quad stable.
Also setting the antigravity properly adds to the smoother rolls and loops.

Anti gravity should be set to 3. Though I don't know how it exactly works, I read the antigravity raises the I in flight.
Do need to be a little careful with the FPV feed when you set the I too high, the raising of I can introduce interference on the FPV feed.
Adding antigravity can raise the I so much it screws up the video. But with PIDs around default values it will probably be fine.
