The velcro is a bear to work with. I'm probably not going to use it all. I'm not securing these down right now, but am prefitting them only. I want to do engine test first to make sure there are no leaks. Then I'll put in the pads. Carpet will go in very last when I'm ready for first flight.
I also noticed that the 90 degree BNC elbo improved the flow of the antenna cable. There is less kink like this.
So there will be an un-used hole in the carpet. People can ask me about it. I'll tell them: "Measure twice. Cut once."
