Default RE: Falke Biplane 60 build

for the next section, I need some advice. I built the N-struts and reinforced them with carbon fiber, But they look a bit tall in real life as opposed to the plans. The goal was to get the top wing one cord-width above the bottom wing, or about 9 inches, to reduce interferance between the two wings. Aesthetically, I don't think I like it that high, and I worry about an upward pitching moment with the top wing so high above the thrustline. I think with some semi-major surgery, I can lower the top wing an inch or so (probably closer to 3/4 of an inch) by cutting off the bottoms of the N-struts, but it would also mean cutting my already laser-cut wing struts in half and taking a chunk out of the middle. Do I make the change, or leave it as-is?
