The RE-L10 "Poodle" Liquid Fuel Engine is a size 2 liquid fuel engine.

Product description

A more reasonable engine for rough economic times, the Poodle engine doubles as a BBQ when at low power.

Rockomax Conglomerate


The Poodle has a moderate thrust to weight ratio, offset by its relatively short height, high specific impulse and thrust, and gimbal range. It performs very poorly in atmospheric conditions but it excels at vacuum operation. It has the highest Isp of any non-DLC LF/O engine, making it very fuel efficient in vacuum. This makes it an ideal engine for large-diameter, upper stages of rockets for landings, orbital insertions, and transfers.

The gimbal functions by having the whole engine structure mounted on 4 hydraulic arms. The two nozzles cannot move independently, so the gimbal will not assist with roll control if it is in line with the rocket body.


As of version 1.10 this engine has two variants that can be switched in the editor.

Double bell variant
Single bell variant
The different variants of the engine


  • This part was previously designated as the LV-909 Liquid Fuel Engine (Large).
  • The double bell variant of RE-L10 was likely inspired by the double RL10 engine configuration on Centaur upper stage.
    • The single bell variant of RE-L10 was likely inspired by Vinci used by the Ariane 6 rockets
  • According to Squad members who were not around when the part was first implemented, Prior to KSP version 1.6, the RE-L10's appearance was based off of the Payload Assist Module used on Space Shuttle payloads as it shares the same overall appearance; however, the parts are functionally different- the real-world module is a small spherical solid motor similar in function to the Sepratron I. According to the developer of the part, however, the model was not based on that engine.
  • In the past, it had been outperformed by LV-T30 Liquid Fuel Engines and clusters of LV-909 Liquid Fuel Engines, though this is no longer the case.


  • Added single bell variant
  • New model and texture
  • Specific impulse at sea level increased from 85 to 90.
  • Part rebalancing due to new atmospheric model
  • cost increased (600 → 1600), mass reduced (2.5 → 2)
  • Retextured
  • (Part rebalancing) Mass reduced from 4 to 2.5, thrust increased from 135 to 220.
  • Initial release (with LV-909 title and description)
