Two weeks / too short.. .This is an extension of my feelings about learning to Glide at an aerotow only site,Yes, you can learn to pass the test in a fairly short time but you have not had time to absorb all the other stuff by osmosis in the bus/bar/coffee shop/whatever.. .As someone else said, it`s probably a good idea to put in some concentrated flying to start with, just to get over the usual hurdles, but then take it slowly.
