Being playing with propeller and helicopter parts from spaceport ("f" to auto hover, by the way) and god damn I hate bloody spaceplanes! Balance is so god damned hard! Anyone seen any really good tutorials for planes? The more detailed the better. I am tempted to also use the hack tool to put things at/around, say, Duna so I can experiment with craft without having to fly multiple missions (waiting five minutes for a launch window each time). The margins of error involved in spaceplanes is so slight it would drive me crazy to have to repeat a whole flight just because the balance is slightly off.
