@Precog no not necessarily the only solution. There is the rudder trim. This will help a bit but not 100%.
Here’s a simple explanation of couple aviation terms. With your head...
Look up look down, this is pitch
Look left look right, this is yaw
Tilt your head left or right, this is roll (or bank)
So the left turning your seeing is really a bit of left roll from the prop, right? So applying a bit of right rudder (the rudder controls yaw...L and R but not really the roll) it can help a bit. Some planes will also have an aileron trim (ailerons are what make the plane bank/roll L and R) which are more helpful, but this plane doesn’t have that so long story short, yes, you have to always manage the plane.
Being new to flight sims be patient, there’s a lot to learn!
