The bottom needs to be open when using the piano hinge to get the correct downward deflection. Some have covered the opening with a gap seal (easily done) but I recall that there is no aerodynamic gain in covering the opening with the RAF48 airfoil. If you use the new airfoil, put on a gap seal. You never see the bottom side of the wing with the KR on the ground and when I fly by at 180 MPH you won't notice the gap either !!:-) Do yourself a favor and put your building time to something more productive then re-inventing the aileron hinge.
