Actually, I'm not much on digitals either but do use typical sport servo's in a lot of planes. I'm not talking about being a precision flyer either. I can tell when the control centering isn't right and the trim won't set up right. Sometimes I have let it go but most times I fix it. Usually it's a sloppy or worn servo or a worn hole in the servo arm. I just think you'd be much happier with planes where the centering is the same every time andthat you don't have to compensate all the time for drift in roll or pitch. I don't think it's a waste for middle of the pack fliers. You might find the airplane more comfortable to fly and maybe make you look like a much better flyer.
