This. I can't say I "hate" mods, I've just made the informed choice that I would like to move with stock parts as much as possible and build up my skill with them. Experimentation has lead to some strange-looking methods of fixing construction instabilities and flight/control related issues; in time I envision that the game will feature components that mods currently bring to the game. I admit that I'm entertaining myself this way, and may have to re-learn with each Alpha update, but it keeps the dust off the braincells . That said, I do like the ISA MapSat pack, it adds one extremely useful tool that I can not only use for in-game nav, but I enjoy crunching the raw data with external utilities as stated in other threads. In my mind, it simulates that which JPL engineers/scientists do for their living but on a scale I can handle.
