Plant-Based Rocket Science

Sorry, forgot to mention that I can't launch from the runway in a KCT simulation, I havent tested it in the actual game world, only in simulations. As for screenshots, I don't have any, but it just launches from the launchpad instead of the runway even when I am in the Spaceplane hangar.

I have an RP-1 install that followed Carnasa's tutorial for the installation: (I did not include Waterfall or KER) I attemped to create an X-plane, but it's not letting me launch from the runway. Help me pls
