The LV-1R "Spider" Liquid Fuel Engine is a radially mounted liquid fuel engine.
It is one of the lowest-thrust engines in the game, tied with the LV-1 "Ant" Liquid Fuel Engine and the IX-6315 "Dawn" Electric Propulsion System ion engine.

Usage
The Spider is the radial version of the LV-1 "Ant" Liquid Fuel Engine, with similar designs and vacuum thrust. Unlike the Ant, the Spider has a much higher atmospheric Isp, and a lower vacuum Isp. In addition, the Spider is capable of thrust vectoring.
Spider engines are less efficient than Ant engines in vacuum. However, the Spider's thrust vectoring allows a probe powered by Spider engines to forgo a reaction wheel, reducing dry mass.
Variants
As of version 1.7 this engine has two models that can be switched in the editor.
Changes
- New model and texture
- Added 2 variants
- Gimbal increased from 8° to 10°.
- Cost increased from 150 to 650 (and made meaningful)
- Thrust increased from 1.5 to 4 kN.
- Initial release
