Aerobee need pressure-fed tank, default tank for engine is not pressured.

[alimoncul]

Here is the tank config from RO : https://github.com/KSP-RO/RealismOverhaul/blob/master/GameData/RealismOverhaul/RO_SuggestedMods/Taerobee/Aerobee.cfg#L386

Fuels not correct either. Do i have a problem with Real Fuels?

[SpaceCatHaxor]

Looks like a config issue, I don't know exactly how configs for Realfuels and such work, so I can't fix it, but its not surprising that its gone unnoticed. RP-0 heavily encourages you to use the procedural fuel tanks, and the upcoming update makes them practically mandatory with tooling costs.

Something is wrong with your setup, it still has LiquidFuel. RealFuels should have removed that entirely. Are you sure the rest of your RO + dependencies are set up correctly? RealFuels requires SolverEngines, which isn't included in the dev branch download, you'll need to get it separately or from a release.

I followed this order with the notes, game never crashed during installation process. I putted 4-5 mods and tested it. I got solver engines.

Right, but which versions of each mod are you using. For example, if I invoke AVC for the version check I get;

With the updated RP-1dev testing/replacement DLL's from https://github.com/KSP-RO/RP-0/issues/749

Now this (probably) doesn't match your mod list, but when I add the Aerobee engine to the tank (with the above build/versions) I get IRFNA-III/Aniline/Furfuryl as the fueling options

Which suggests an issue with your mod versions, or DLL mismatch (preventing loading) so please post your ksp.log or version information so this can be investigated.

Alright its completely my mod install issue.

here is the ksp.log : https://drive.google.com/file/d/1Aw9V__5d8eMeRPwnf7sHV1GmQcPCOYEq/view?usp=sharing

@alimoncul You have ModularFuelTanks installed. Remove it. It is not compatible with RealFuels.

[alimoncul]

removing modularfueltanks fixed the issue. Thank you 😄
