Hello,

There's a basic question for you all. I noticed that while taking off,
with calm winds, the airplane always tend to go on left side off the
runway. Calibrated the joystick many times, same thing. I was
wondering if this is just the joystick that is not calibrated
correctly, or does it happens in a real airplane?

I think a read somewhere that this happens because of the rotation of
the propeller. Is it true? Thanks!
