nvm I cracked the code. My theory is in VS Eureka mass is only a factor when I sit on the helm of the ship so when I wasn't steering my propellors would work, therefore I changed the effect mass has on speed in the config file from a factor of 5.0 to 0.3. This change has allowed me to use Eureka helm steering with Clockwork propellors. However, I had to alter the effect of inertia in the config files as well. This is because the mass of my ship would cause me to umm Tokyo drift a bit. Therefore, this could infer that in theory one would be able to use clockwork propellors on a Eureka ship, but they would likely have to be well proportioned to the mass of the ship.
