Hi I've made several ft models and loved flying them all. One weird thing i noticed is that all of the airplanes want to severely roll to the left. I countered it with a right down thrust angle but as i want to transition into 3d planes, The thrust angles troubles me as the plane still doesnt prop hang or hover and keeps deviating. The motor is an 54 gm avionic 2826 1350kv and a 800mah 40c 3s. Is my motor too big or its  something else?

Since you find this issue with all the models, it could be because of something outside the aircraft as well.

One possibility: The roll stick on your transmitter is not perfectly centered (or) it outputs values less than 1500(assuming 1000 to 2000 microsecond as range) when it is at rest (or) the potentiometer is not as good as new.

Try: Confirm that the value is as expected when the roll stick is idle. If not so, just trim it out and try flying again.

Well my Nutball has no aileron surface only a rudder. I have an FSI6 and have perfectly aligned rudder. Still the nutball wants to roll left when launching.

Isn't this the issue of torque roll ?

Please tell me more about it. I googled torque roll and found lots of info but nothing that I could grasp. Whats a p-factor? How do I fix Torque roll?
