      Hi everyone, I'm a newbie to the forum and love aircraft modeling. I'm just learning the ropes of airliner modeling and could only sigh with envy at the quality of work here. I joined to learn as much as I could from you guys and get some guidance.

      I've always wanted to depict a 747 in landing configuration with flaps/slats deployed. I've started practicing on a Hobbycraft 1:200 747-100 before I try my hand on a Hasegawa. I picked up some JNH flaps and I've managed to cut out the movable surfaces and flex the wings.

      But now I'm wondering about how the slats and flaps would adapt to the wing flex --- would they flex, too, to account for the bend in the wing? I'm thinking that if they were straight wouldn't they jam if they moved into or out of the "bent" wing trailing edge opening. I'm asking really if I should start bending the slats and flap parts. But then again, I couldn't see how they could bend lengthwise and deploy cross-wise at the same time. I'm really confused -- help, please : (

      I'm not an aeronautical engineer but, I would strongly suggest that in landing configuration, the wings are done with their flexing ( bending) to a great degree and the hardware hung out to dry on the trailing edge of the wing at this point are in alignment to the degree designed into the whole structure. Check out Airliners.net for photos of your subject in various modes of flap deployment and landing attitude.
      Happy modeling.

      No, the flap and slat sections don't bend. They are rigid structures. What allows them to bend is the way they're mounted on the tracks.

      Not sure if you have looked a Brad's work, the master of deployed flaps and slats, a lot of very helpful information
