Translations:KAVAN Beta 1400 Kit - Instruction manual/101/en

The rudder of a model without ailerons (you might be already familiar with) controls the bank angle, which then controls the rate of turn. The natural stability of your model keeps the wings level in normal straight flight. Since your BETA 1400 features "full-house" controls, including ailerons that are the main means to control the bank angle, the use of the rudder is slightly different. You can even start to control your model without using the rudder, but later, you will learn the correct coordinated turn actually requires both aileron and rudder inputs.
