RE: Newb questions: looking for trainer
Being nimble and easy to fly are often a compromise. Especially in a beginner airplane
The airplane has horizontal stability designed into the wing with dihedral rather than using ailerons. You will find that it turns nicely with just the tail feathers.
There are many schemes of control, especially with the beginner planes. Some only have a rudder and motor control. To turn use the rudder. To go up or down use the motor
Some planes have just ailerons instead of a elevator or rudder. They go up - down or left - right with just the ailerons which they call elevons.
