When compared to the [[Swivel Engine]], this engine is better. It has higher thrust, higher specific impulse at sea level, and more thrust vectoring. However it is slightly heavier and more expensive, but it is still a good engine nonetheless.

Usage

Similar to the real life comparison LR-87 engine, the LV-TX87 "Bobcat" Liquid Fuel Engine is best used as a first stage engine. If playing Career or Science mode, it offers the highest sea level specific impulse when reaching heavy rocketry in the tech tree. Therefore, it should be highly considered when building medium sized vehicles.

Unlike the double bell version of the RE-L10 "Poodle" Liquid Fuel Engine, the two engine bells can gimbal separately, allowing the engine to provide roll control. Additionally, the gimbal statistics can be toggled separately using tweakables.

Product description

Meow! One of these engines gives more than enough thrust to jump as high as the sky, so we gave you two.
