As for the gimballing engines, if you don't like your engines to vector then just lock the engine gimbals, simple. Gimbaling has nothing to do with engine capacity, or for that matter the engines themselves. Rocket engines generally are not capable of vectoring their thrust (the ones you can kick that is, not the in-game ones), rather the vectoring is a function of the engine mountings. Engineers will either use fixed or gimbaled mounts according to the specific design requirements of the vehicle regardless of the type and capacity of engines they're using. -- "Take-offs = landings... it's been an OK day"
