Vanamonde Posted May 23, 2018 Share Posted May 23, 2018 Welcome to the forum. Sorry I can't give you any modding recommendations, though. I don't use them. Link to comment Share on other sites More sharing options...
Blasty McBlastblast Posted May 23, 2018 Share Posted May 23, 2018 Hi @Nervenkobold_GER and welcome to the forums! It sounds like you have discovered that most RO engines have limited ignitions and/or ullage requirements for fuel. From the wiki: Restarting an engine is a tricky prospect, requires just the right conditions, and even then most engines only have a limited number of restarts. Issues such as freefall causing propellants to float away from their feed lines complicate the matter. To solve this, LVs use small motors called "ullage motors" to settle the propellants before igniting their main engines. Spacecraft often use RCS for this purpose. Assuming propellants are settled, the engine must be able to ignite; most first stage engines have only one ignition (often provided externally), though some upper stage engines have multiple ignitions. Because of their simplicity--needing neither to ignite their propellants nor spin up a turbopump--pressure-fed hypergolic engines have effectively infinite ignitions. Indeed, that's all RCS is: sets of small hypergolic (or catalyzed monopropellant or cold-gas) pressure-fed engines. https://github.com/KSP-RO/RealismOverhaul/wiki/False-KSP-Lessons#myth-rocket-engines-are-infinitely-restartable Link to comment Share on other sites More sharing options...

Blasty McBlastblast Posted May 24, 2018 Share Posted May 24, 2018 The Realism Overhaul thread has a good list of recommended mods, also Scott Manley has made an excellent youtube video explaining the whole realism process Link to comment Share on other sites More sharing options...
