LE slats and flaps-worth the effort?
Got two planes on the bench I'm trying to decide whether or not to add slats and LE flaps. I'm at the point in construction to decide on each. One is an F4D Skyray-it had spring loaded slats, which closed with airspeed. I think I would go with a servo operated system. I wouldn't have a clue how to determine the necessary spring requirement-though I guess you try hit or miss. This plane also had triangular shaped 'trimmers' aft, adjacent to the fuse and inboard of the elevons, I'm also going to try to incorporate. The other plane, an SU 27, had LE flaps which operate automatically on the full size-in conjuntion with the air brake. I guess it boils down to whether these things just look cool, or whether they would povide any noticeable flight characteristics. I might add neither plan incorporates these, I just like the scale effects. Any thoughts? Bill S.
