The Grand Caravan doesn't have a Wing Leveler. This is sometime called the Yaw Damper. Y/D switch.
Ah... So! Have to go try turning off the Wing-leveler when I want to bank all the other planes.
Hope this is the fix I was seeking..............

and you could have figured this out 8 posts ago when Hagar told you about the LVL switch.
Granted you have already expressed your perfectly content using just the keyboard, but if you went to a local computer store and got at least the Saitek ST290 Pro joystick that has a "twist" feature ($20 at Walmart), Then you will really see your sim come alive!!!!! It will no longer be "just a game" it will start to transform more into a SIMULATOR which is what it is supposed to be.
Do real Airline pilots learn how to fly A380-800's using a keyboard??? NO!!! they learn in a SIMULATOR that has up to 8 monitors, yoke, rudder pedals, numerous hydrolic actuators, MILES of computer cables....... if you want to feel that you are flying the real thing, then why not try to get as close to it as you can at your house????? Why settle for just the keyboard?????
