Hey Enrique:

Thanks for the info

How can I get in contact with this guy?

I need information about how to reinforce the leading edge section of the wing and how to hinge the leading edge flaps because the actuating mechanism can beclearly seen in the video. The actuating servo and the horn, are located at the wings root as I was thinking.

As you can see, the landing speed is very low thanks to the leading edge and trailing edge flaps and thanks to speed brakes, despite every one commented.

Thanks again
