If I am not mistaken, you can change it yourself by editing jet-engines.cfg found in "\Kerbal Space Program\GameData\RocketSoundEnhancementDefault\Configs\Squad". Open the config and change volume value to whatever you like. https://prnt.sc/Pq5TCuw6TW9C

Lol, I tried that and failed miserably, the drag on that receiver is insane. The best results I got was when I turned the part upside down and put engines on top, still achieved only 16000 m with ca 5000 dV. I only managed to put it in orbit when exploiting the ability of engine plates to make parts dragless. Best solution is to build it in orbit using mods like global construction or extraplanetary launchpads.

Dunno if I am answering too late but you can store hydrogen in hex segment gas tanks (gasseous state) and the liquid form in almost any tank provided you have interstellar fuel switch. Water can be stored in e.g. hex segment liquid tanks (or whatever they're called) and then electrolysed using ISRU electrolyzer pr the All in one ISRU into oxygen and hydrogen, which can be then turned into HTP. Recommend consulting first page of this thread, there is a neat flowchart of all ISRU processes.

Didn't you ran out of power for example? I just tried to replicate your problem in my testing save and all worked fine for me (switching to another vessel and throttling down to 0). I am too lazy to bother with sharing the craft file, but it was just the the daedalus engine, MHD generator, plasma fusion generator, big sphere tank with fusion pellets and a drone core. Tested on KSP 1.12.5 and latest release of KSPIE.

No, I never managed to get them to work, I suspect that there is a problem with Helium 3 resource generation in my install. Your post made me think about it again and an idea came to mind - edit the miner's config to make it harvest regolith (it's regolith miner afterall) instead of He 3 and then add ISRU like capability to convert it to He 3. I have no experience in ksp modding so don´t get your hopes up.

Oh, I didn't realize that, thanks. I thought they harvest regolith and then purify helium3 out of it. How is one supposed to scan for helium3? I don't see it in Scansat's interface.

Hi, has anyone tried to use the PK-dust collecting system (the big one)? Currently landed two of them on the Mun, however they are not harvesting, the context window says that there is "nothing to harvest", despite being in a regolith hotspot i found using Scansat. Any help is greatly appreciated. https://imgur.com/a/KIyQd5z Update: tested the same craft in sandbox on various locations on Mun, Minmus, Ike, the harvester didn´t work on any of them. Tried also regolith drill from Interstellar extended and it worked fine. I guess there must be a communication problem between Community resource pack and Far future technologies?
