I have been thinking of another way to attach and actuate the leading edge flaps on my Buttercup wing. I dont like the hinges for a number of reasons.
I am thinking about simply screwing the top of the backwards "C" to the main spar and let the bending of the metal act as a hinge. I would then set up an actuation to make the 1 1/2 inch movement of the nose of the LE. I would rig it to be propped up under normal flight conditions and nosed down for landing. I would not drill holes in the spar, but simply connect the actuator inside the cabin with the flap belcrank.
Obviously it is a major challenge to come up with a light but solid means of doing this. I have a couple ideas, but they are not clear enough to even prototype.
I need something that will let me move the bottom of the backwards "D" about 1 3/4 inches fore and aft. I would like to attach it to all of the "D" ribs. And be able to get it on and off in some reasonable way.
Maybe that is where Witt got stuck.
