All aircraft rolling to right

[NLS61]

Well this is actually normal
Its because the torque of the propeller.
You can give eight-er a bit of counter aileron or a bit of rudder to compensate.
The latter will have you side slipping a bit but both the solutions or combination thereof cost something in drag.
Its to find the sweet spot if you can you’ll have an advantage over your opponents.
The designer of the planes have already done some of the work for you by positioning the vertical fin out of the longitudinal axis of the plane itself .
But anyhow that only works perfect for just one airspeed.
