I have had this problem before but I don't remember how I fixed it. I am used to pressing S on the keyboard to pull up and w to nose down with an aircraft in KSP but on this new aircraft I am making it is the opposite, when I press W it pulls up and when i press S it pulls down. I am not sure what to do. I rotated my control surfaces 180 degrees and the probe module and that did not work. If you know anything please leave a comment down below. Thanks!
