I have found the default planes react too quickly to small control movements if the settings are on Easy. They respond better and are actually easier for me and my grandchildren as 'new pilots' if the realism is set to medium or high.
A Very Important setting if you have AI is to turn off crash detection for other aircraft, especially FSX. That way airport vehicles won't cause you to crash when they try to drive through your plane. Also, FS doesn't keep close enough track of AI aircraft to avoid crashing your plane accidentally.
