The '''LV-T30 Liquid Fuel Engine''' is a basic [[liquid fuel engine]].
  
The LV-T30 is currently the only [[Liquid Fuel]] engine and is also the only engine with controllable throttle. This makes it very useful for precise, controlled maneuvers and conserving fuel. They are not placeable on radial decouplers and are typically reserved as a main engine after liftoff. The LV-T30 must be directly below a non-empty FL-T500 Fuel Tank to produce any thrust.

The LV-T30 Liquid Fuel Engine is a basic liquid fuel engine.

Product description

Although criticized by some due to their not insignificant use of so-called "pieces found lying about", the LV-T series engines have proven themselves as comparatively reliable. The T30 model boasts a failure and rattly bits ratio below the 50% mark, this has been considered a major improvement over previous models by engineers and LV-T enthusiasts.

Usage

As a liquid fuel engine, the Reliant has throttle control, shutdown and restart capabilities, making it easier to control vehicles safely and accurately. It also has nearly twice the specific impulse of the solid motors that went before it. It cannot be placed radially; however, since rocket fuel tanks can be placed radially, the Reliant can be the basis of liquid-fueled strap-on boosters in parallel configurations. Since the engine lacks thrust vector control, other means must be incorporated to make sure the vehicle remains pointed in the right direction, such as parts with reaction wheels, aerodynamic fins and control surfaces, and parallel operating gimbaled engines such as the LV-T45 "Swivel" Liquid Fuel Engine.

The Reliant has the highest Thrust to Cost ratio of any liquid fueled engine in the game, meaning it produces a kN of thrust most cheaply. This makes it one of the most cost-effective engines in career, although compensating for the lack of gimballing may cause the final rocket to be more expensive.
