Dear All,

I am scratch building a Feiseler Storch using Uncle willies Plans. I fully understand the function of the leading Edge Slats. As the front opening, of the slats are wider than the rear end, the incoming air is pushed towards the trailing edge of the wing there by assisting to maintain the boundary layer.

But according to the plan it seems that the front opening of the Slats which are mounted on the under side of the Elevator, is narrower than the rear opening.(which is not the same as the Leading Edge Slats.)

I would like to know the function of the Elevator Slats.

Any advice is very much appreciated.
