I was flying a hull last weekend for the first time and I noticed a lot of stick pressure when I went up on 1 hull. Is this normal? I do not have very much pressure when I am on both hulls. I also noticed some humming coming from the rudders when I am going about 10 knots. I just adjusted the mask rake and have restored both rudders, and regelcoated them. I have done a lot of work on the cat and am trying to get things adjusted again.

Thanks airborne
