An aircraft designed to fly with rudder will fly nearly the same as an aircraft with ailerons. People that think that an airplane flies alot better with ailerons have probably very little experience flying without them or have not flown an aircraft designed for rudder control.

Ailerons are effective at normal flight speeds but not near a stall. The rudder is always effective. I've seen many a crash at slow speed where the pilot tried in vain to maintain control with the ailerons neglecting to use the rudder. Some even claim they were victims of interference because they thought they lost all control of their aircraft. They didn't know how to use the rudder and probably learned on an aileron equipped trainer.

Aircraft designed to fly with rudder instead of ailerons:
1. Must take off and land directly into the wind.
2. The airplane will roll but the rolls will be barrel rolls instead of axial rolls.
3. The rudder will be very effective at all speeds, even near a stall.
4. People that learn on a rudder plane learn from the start how powerful the rudder is at all flight speeds and learn to use it. People that learn on aileron planes rarely learn to use the rudder.
5. Rudder airplanes are easier to build and repair and much simpler.
6. Rudder planes are much more challenging to fly inverted for extended periods.
7. Rudder planes can perform most of the same aerobatic maneuvers but the maneuvers won't be as crisp.
8. Rudder planes are more stable and easier to fly than aileron planes.

Flying with ailerons is very similar to flying with rudder. You will have no trouble with the transition, just remember that the rudder is still there and waiting to be used at the proper time. If you get slow and the ailerons don't work use the rudder!
