The lack of ability to rotate for take of can be overcome. Improving the propeller life will probably be more difficult.Interesting in what way, and for whom? I wouldn't expect much in the way of propeller life, or much in the ability to rotate and be anything other than a fast water taxi.
First, if I understand canard aerodynamics correct, the higher take off speed and reluctance for a canard airplane to rotate is due to less elevator authority than an orthodox airplane. This lower elevator authority is caused by a design choice to not introduce possible dangerous handling characteristics. Ref. Curtis Ascedender.How so?
