Hi,
I have Pixhawk on my Skywalker X-6
My Pixhawk works perfect when on ground, but doesn't allow me to roll the plane when in the air.
In chart above I try to roll the plane to right (RCIN red lines), but it doesn't react (RCOUT green and blue lines). But as you see it reacts to wind trying to stabilize.
Any ideas?
I had similar situation in the air, but thought it's related to speed, like Pixhawk tries to prevent stall if I decrease throttle. But in this case it didn't roll immediately after takeoff and increase of the speed didn't help.
Attaching log file.

Is this in Autotune mode or FBW?
If this is Autotune at first you will see no response, then a little response and will gradually build up as you manipulate the stick.
For auto tune, take off with PLENTY of room to fly in a state line upon entering Auto-tune (as at first there will be VARY LITTLE response). Quickly but surly move Elevator full up, full down at least 20 times. Each time you do this you will see more and more response. Repeat the same with Ailerons and the same think will happen.
You MUST have a lot of room because at first the plane will not respond to stick movements. Keep a high altitude also to avoid any trees or hills ect.
I would also have the next mode to be Manual so if needed you can drop into manual quickly if the plane is heading for something. this is the only way to regain control.
Once you have used Elevator and Aileron a good few times 6-10 then you should be able to control the plane a bit.
Each movement will become more responsive.
Assuming all goes well and you don't have to switch back to manual, keep flying for as long as you can. The more you fly the better the auto-tune.
Flight mode:- If you have a 3 positioned sw I recommend Top Auto0Tune, Middle Stabilized, Bottom Manual.
So if you hit this switch quickly you most likely go full down to manual.
After Auto-tune, land in auto tune, disarm.
Take-off in manual and try out Stabilized.
then take it for there,
