I don\'t think there is any list like that, but I\'m happy to share the results of about 20 hours of searching through mods and trying them out: First and foremost, I advise you make a complete backup of a clean, patched install of the whole game, or at least the Parts folder. This way you won\'t have to wait for a repatch after you completely clog up your Parts and get lost in the heaps of useless parts and have to wipe/reinstall. Zoxygene_0.5.2.zip ZO2_Powertech_panels.rar PowerTech_Plugin_v0.2.5.rar PowerSat.rar The above 4 are to give you something to do on your flights. An even more intricate system is dynasat_v_0_6_1.zip and SatelliteRelays_v0_5.zip, but I haven\'t tried those yet. Probodobodyne Construction Kit - v0.5.zip is also in this category - it contains mostly props, but also 2 nifty unmanned capsules. KSP Silisko Edition 1.2.zip - BE CAREFUL. Definitely do NOT install it like the author suggests (you will lose a number of components if you do), rather, don\'t overwrite the existing parts, just add the ones that don\'t exist in the default set. And not all of them, at that. The only parts I ended up using from this set are the excellent non-nosecone parachute, the small weak decoupler, the nosecone for the tanks... and maybe something else. Do not use the modified engines and fuel tanks, they are more effective to the point of cheating, IMHO. MechJeb_1.8.4.zip - guess you already know this one. I am still to use it - for now i am just enjoying manual flights, with an M screen trajectory predictor. If you are into space history, there are several excellent sets of Russian space vehivcles. be warned though - parts from them usually don\'t work well with default ones. The files are: Kosmos LK 1.0.rar Kosmos 4.1.rar Angara 3.0.rar Noyuz Pack 1.2.1.zip Guess these would keep you occupied for a while. Have fun : )
