Basics

- A rocket engine that uses the burning of a liquid fuel and liquid oxidiser to produce thrust

- These require no ignitor, as as soon as the liquids touch they ignite

- Can be throttled, stopped, and restarted

- Unlike the Open Source Liquid Fuel Rocket (Fuel Oxydizer Variety), these can be started and stopped as long as there is fuel

- Useful both as a sea level booster, and as a high atmosphere/orbital rocket (albeit with nozzle modification etc.)

- Is extremely reliable
