I am new to drone world,
I have successfully built my Tarot 680-Pro.
I could fly it, but my Yaw,Roll and Pitch are too sensitive, so thought to autotune.
So I did change Roll/Pitch sensitivity and on fly tried autotune.
Unfortunately my hexacopter crashed during autotune, I saw logs were dumped some Chinese language and those big files were not accessible, literally OS forced me to format my SD card to use it.
So Sorry no syslog to analyse.
Transmitter: "FrSky Taranis Q X7 ACCESS 2.4GHz 24CH Mode2 Transmitter with R9M 2019"
ESC: Hobbywing XRotor 40A-OPTO ESC
Motors: Tarot 4108 High Power Brushless Motor (380kv)
Flight Controller: PIXHAWK PX4 2.4.7
Firmware version Copter 4.0.5
Battery:6S.
Please help me what was wrong?
Any way to make drone smoother, smooth yaw like slow motion.

The soln is not on the drone or the board ...its on the radio. Search here or google with dual rates, expo and curves on openTx.

Thanks,
I did try modifying curves, added maximum point 21 on curve, still it is sensitive.
I shall try again after studying radio.

I wouldn't recommend that you do anything of that sorts on the radio, no curves! no dual rates nothing

Do everything on the pixhawk only!

Decrease your gains as per your requirement.

Increasing the gain makes the craft sensitive to both user inputs and external factors (wind) and decreasing it makes it sluggish.

So best way is to decrease your gains by 10 units till you feel it's comfortable in flying.

These setting will change if you change anything on the craft like payload weight,propeller size or pitch, motor,lipo etc

Ok thanks alot, any video link or webpage to do that?

Pretty sure its covered on Rcgroup or even the ardupilot forums! video wise you can probably check on painless360 channel or on Dennis Baldwins channel

I could make Yaw, Roll and Pitch smoother by selecting Input Curve Expo, first I chose value 100, but that made Yaw,Roll and Pitch very slow, so adjusted to 75 and now it works perfect
