Actually been doing some modelling today despite watching the Belgian Grand Prix and chasing Kerbals around Kerbin while they float helpless in their tin cans called space craft!
Note to self, Ignore the Engineers report in the VAB about nothing for the solar panels or other power generation to be used by. Reaction Wheels use energy! That's why I have a rescue craft fitted with Mechanical Jeb and a probe body playing catch up with one craft I put in orbit to practice docking with a previously launched craft of the same design. Both are now floating around waiting for rescue because the solar panels I fitted were from a mod for circular solar panels which didn't open

hence why both craft are helpless in space

Mechanical Jeb might be termed as cheating by some but in this day and age there are space craft being launched and automatically rendezvousing with the space station regularly so why not do something similar if your having difficulty doing such things as circularising your orbits like I do. I still design my own craft and come up with the tasks that each craft is to do and I also plan to do the fine control stuff myself but why screw things up when the computer can do that for you?
