It required up pitch trim adjustment to the limit and more. This was with the GU canard. I have not had experience with the Roncz canard yet and I won't have if I can avoid it.

It should collect on surfaces and add weight on composite aircraft just as well as on tin cans. Ice usually collects on surfaces with sharper radii faster than on more rounded surfaces. So the canard configuration might have more of an effect than the material. I remember an article in a CP that recommended some guards over the elevator hinges. Turns out that the hinges can freeze up in icing conditions. Regards, Dave -- David R.
