The original builder of my project did a very poor job on the wings and canard and it took considerable work to get them to where they are today. Unfortunately, my Roncz canard has twist in it that causes the aircraft to roll, and requires roll trim at every power setting. I was going to live with it until I was told by Gary Hertzler that if I incorporate the Klaus elevator hinge pin location modification, I should see an additional 5kts. That right there motivated me to make the call and go for it. Today, I built a new work bench that is 144" x 24" specifically for building an all new Roncz canard for N316NM. :)
