Real Fuels/Procedural Parts Help

[trnr428]

I recently started playing KSP with RP-0 right off the bat. I have been having some fun except when I attempt orbit because my RCS thrusters will not work. I have deduced the problem to the fact that it seems like the procedural tank is missing functionality types. I only have the options for structural and fuselage. I see everywhere else (YouTube, forums, etc.)  (and even in the part description!!) that there are options for default, balloon, service module, etc.. I am convinced that I need to change the the tank type to service module but it is not there. I added modular fuel tanks to my game data but the procedural tank is missing after I reload the game.. the modular fuel tanks config file is located in the procedural parts module manager in game data.. I'm completely stuck.. Please help!

The other types are locked because you haven't unlocked the tech nodes which unlock them. Fuselage, like ServiceModule, is highly pressurized and thus you can place RCS propellants in it. Set your thrusters to whatever propellant you want, then place  a proc tank, make sure it's set to fuselage, and fill it with that propellant. Note that you do need a valid fuel crossfeed from the tank to the thruster, so if you have parts in between with No Crossfeed, it won't work.

Note that RCS effects are weak to nonexistent for some reason, so instead of relying on visual FX, rely on propellant consumption. Turn on RCS (you will need sufficient avionics to do so), and try thrusting. If the propellant in the tank goes down, they're working.

 

You may want to look at the RP-0 tutorials, they explain this sort of thing. https://github.com/KSP-RO/RP-0/wiki

 

Also note you get very little thrust out of them, practically zero, at sea level. Try in space.

Ah, I think I found the problem. It wasn't what I had previously thought (thank you for explaining that to me). I narrowed it down to my thrusters not being assign to the rcs action group! I am completely new to ksp and I have no idea what action groups even do, but it is now something I will look into. Thank you for your suggestion on using them in space because I probably would have never known to do that as I was looking for the visual FX! I do have to ask you when you think a patch for the rcs FX will be coming out, though.

As soon as I get time (or someone else does), not sure when...

Aghh I am again having issues. I have 138/223 N class attitude jets attached radially to a fuel tank. The engineer says that they are not receiving monopropellant and continues to show this for nitrogen and nitrous oxide. I haven't tried helium yet (as I don't want to purchase it yet, and I need the NO2 for the higher specific impulse for the small tanks) but one thing that makes the message go away is if I use monopropellant and mess with the mass slider. Simply loading monopropellant into a real fuels tank should not work, and I cannot understand why it will not register that there is fuel in there, even after switching fuel types back and forth, tank shapes, tank types, deleting and re-adding tanks and thrusters. This is what happened last time but it seemed to have solved itself and I have no idea how. I have also found that the engineer is saying that there is unused NO2 source as well as the battery that's attached. I checked all of my connections and everything seems fine.. crossfeeding is enabled for all of the couplers.

Ignore the engineer report. It's still thinking you're playing stock KSP.
