AutoQuad Forum

All other parameters seem to be ok.
I hope your
#define DEFAULT_MOT_VALUE2T_A1
#define DEFAULT_MOT_VALUE2T_A2
are correct.
I have had similar problems if due to some manufacturing defect/bad handling, 1 prop was generating less thrust.

If the craft rotates CCW, it means a CCW prop is generating too little thrust. So try replacing props 2 and/or 4.

What motor/prop combo are you using here?

I think your values Prop_K1, AM1 and AM2 are way off.
Maybe you can try Prop_K1 around 12.
I usually spool up the mots a little and have a close look at the yaw and listen to the sound. If there is no shaking in yaw and the mots sound good, I am usually close to the right value.

Set AM1 around 5, AM2 around 10 as a starting point.
Also the overall Gain is high to start with.

But there are more experienced quatos users here. Would be nice to have a second opinion.

On my second Quatos build I started with a Ladybird parameter file and I worked for weeks trying to find what was wrong.

The answer is to NEVER START WITH A LADYBIRD FILE.

I attached a parameter file from my first Quatos quad I built. The quad is similar to yours and flies very well.

If you use this parameter file and your XML file, A1 A2, throttle scale, flip, rotation and RC setup your quad might fly well also.

I compared this file to the Ladybird file and found a few parameters were quite different and that was my problem with my second Quatos quad.
