You can set the tailhook lower/raise to anything you want by going to the Settings tab in FS and clicking on Assignments in the Controls section. Click on the pulldown menuthat says Event Category above it and select General Aircraft Commands. Scroll down to the bottom of the category and there should be an entry that reads Tailhook Up/Down. The entry to the left of that is what the tailhook is currently mapped to. If you don't like that setting, just double-click where the key command is and you will be able to select a new key function for that.
