Yeah I wasn't sure originallly about Alpha access because of the price, but then it became clear that it was my duty to cover this
I am so glad that the only annoying bug I've found is the dubious AI and the uncorrectable rolls when you disable flight computers.
I can correct the roll when flight assist is off...sounds to me like you need training.
Make sure that you disable "yaw into roll" in the setting and set it to only roll instead. This helps a lot when disabling the flight assist.
The dubious AI that always falls for the "flying backwards" strategy is however something they need to look at.
