I have 2 questions in regards to maneuvering in RCS mode. I am finding it difficult to maneuver using the keyboard, as even tiny keyboard inputs can send my craft rolling the opposite way. Is there a way to turn down keyboard sensitivity to key/RCS inputs? also, is there a way to autobalance or autostabilize the craft to stop it from continuing to tumble around after a keyboard input?

@KraZIvan - to make RCS less sensitive, you can edit the properties of each nozzle. Set the thrust lower (or maybe it's fuel consumption?)
I think there may also be a control power adjustment. You might get stuck trying to set different thrust levels for rotation vs. translation, depending on your lever arm lengths. Remember to put your RCS as far from the CoM as you can. -

@KraZIvan - well, one thing that annoys me to no end is that the RCS in rotation mode fires all the way up to the commanded pointing direction. That is, it doesn't anticipate stopping on the heading and pitch angle. Therefore, it overshoots many times, wasting huge amounts of monopropellent.
I'm really eager for the modding API to open up. I haven't designed a bang-bang controller for a Type II system since I was a grad student, but it would a fun refresher. -

I like your suggestion, upvoted it a few days ago :D But I wonder, is there a way to make the RCS more lethargic or not as touchy? I may have to check the part settings during the building process

I think you could use my Wind Tunnel suggestion: https://www.simplerockets.com/Feedback/View/b6LbCH/Wind-Tunnel
Even though you might not have "wind"... you could still look at the forces and moments resulting from firing the RCS, and tune them to have the right thrust or positioning to be balanced.

@swope Ty for the suggestion, I will play with the settings. Also an RCS mod for stabilization would be awesome!
