RE: Your Brio setup
With throttle at about 1/4, Place your aircraft in a left hand bank 360 degree turn to the left. Then place the plane in a 360 banked turn to the right. You will notice that the right thrust will "hold" the plane up during the left turn, and the plane will want to falll off during a right banked turn (requiring a little left rudder to hold the same amount of turn radius without it dropping off. The left rudder at low throttle, coming in around 1/3 throttle, keeps the fuselage pointed straight during horizontal and down line maneuvers with low or small throtlle inputs. No mix is in between 1/3 and 2/3 throttle. Then the right rudder mix allows less right thrust required on an upline.
