Brett, Hope you read this; this is the next thing to add to your Aidale offering. After listening to the QS2 guys talk and watching their videos, I really think you should look into making these for the Avid/ KF. Build mounting tabs that can be epoxied and riveted to the leading edge spar and fabricate the leading edge slat or slot after the QS2 or Dakota Cub wing but scaled for the Avid/ KF. I seems like these would be pretty similar to the fabrication of the flaperons. The QS2 has slats that open or close automatically depending on the angle of attack and the air flow through the slat opening by pivoting on the bolts that attach them to the tabs. They said these were patterned after the Helio Currier. They also use VG's on the wing just behind the slat opening. I sure would like to see how these would work on the Avid.
