Unwanted Bank (left or right) – A bank is a steady turn. If your smartphone is leveled and still you get an unwanted bank it could be for several reasons:
- The elevators are not even- one is higher then the other. This creates more lift on the side with the higher elevator, creating a roll.
- The torque of the engine creates a yaw - our software is considering this and compensate with the electric rudder.
- The paper rudder is off balance - the paper rudder is a wing, and creates lift. if its off balance, it creates a force that change the nose direction.
Spiral Dive – The combination of a dive and a bank causes a spiral dive. To correct a spiral dive apply the above technics. You may also want to increase the dihedral in order to reduce the effect of the spiral dive.

The configuration of these models technically should call the trailing edge movable surfaces elevons (combined elevator/aileron). Raising both surfaces evenly does indeed increase lift. The advice here is possibly misleading; the plane with elevons will bank toward the higher elevon (thus the side with the higher elevon cannot have more lift). Just contemplate how ailerons work, its the differential lift!
