Those end pieces on the meter do not engage the leading and trailing edges of the airfoil the same for a symmetrical airfoil as a non-symmetrical airfoil the same way You can see the difference in this drawing. The difference is minor and I always ignore it. I set up all my planes at 0-0-0 for everything and use the moveable surfaces to trim it out. I fly like you do. I takeoff, fly in circles and land. If I land without any damage, it turns me on. Dan
