Thank you very much for you reply. One more thing I don't understand: If I use the first avionics package with 20t weight limit (Guidance unit 1m) and build a rocket heavier than that, I cannot control it (obviously), but if I activate mechjeb's auto pilot the rocket is completely under its control and works just fine. Is it supposed to work this way?

I have installed Realism Overhaul and Realistic Progression for the first time (all via CKAN) and I'm having a problem in the career mode. I've seen some people start with "Sounding Rocket Avionics Package", however when I try to use it a pop up window shows up saying: "WARNING Insufficient avionics! Supports: 0.000t Vessel 0.06t" Is it a bug? What's the point of this part then? I also start with a Guidance Unit 1m, should I use it instead? Thanks
