Works for me. Using left mouse button click on Flap Lever and keep button pressed down.The mini icon tool tip changes and then drag lever to required incremental setting.

Thanks fellas, now I have figured this out on my own.
Like I said up above I am using the pedistal flaps lever with the mouse and I use the keyboard. I also have a very extensive cockpit simulator I fly with so all levers are activated by real levers and switches by couterparts on my cockpit.
I was used to other aircraft to set the flaps at the specified degree before or while pretakeoff check.  I saw that with this A/C, I set the degree I wanted and when I was ready to take off and the engines throttle was activated the flaps would go to where I had set them. I don't know if this is correct or not but it works.

I really like the looks of this aircraft. I was waiting for this 707 for FSX for some time now. I do have one beef though. In order to use the autopilot one has to  look down on the pedestal to work the functions.  This I know is realistic, but it has been really hard to do this and still maintain an atitude with the aircraft. I think a pop up window for the autopilot control would help a great deal. It is a safety issue here and my passengers would appreciate not taking a roller coaster ride when I try to mess with the pedestal control area.  It is hard to chew gum and fly at the same time.
Thanks
