Variable-Camber Wings

WHAT scale builder doesn't want to duplicate every feature of his fullsize prototype? In some cases that's a difficult, impractical goal, but in other cases it's more easily achieved. My latest scale project, a Yellow Aircraft F-18 Hornet, had competed successfully without the installation of operable wing flap and leading edge slat systems. However, competition had since evolved to the point that the extra gadgetry became almost a requirement.
