Thanks for advice. I will try to go this way. Actually I don't blame Roverdude in any way, it is even stated in description that USI-LS is preferred. The idea of my message was just to receive an advice that will let me get solution of my problem and actually I'm really happy that you gave me not a final solution but a path that I need to go to get my problem solved. Sorry for my English, it's not that good. Hope you understood me) And I really like all of RoverDude mods. They bring a lot of new stuff to KSP in the way how it should. It is well balanced and it's a real pleasure to play with USI mods. I can't actually imagine my KSP install without these mods.
