The advice given above is just spot-on and some of the best you will ever get (even if you paid money for it!) When you start on the simulator it will be hard adjusting to the field of vision limitations of a 2D computer screen, but start there and learn to hover. Don't treat it like a video game, practice like it's for real every time. You will save the price of the simulator in crash costs and time your first evening using it! Use RADD's system and if it takes you 3 months of evenings to get tail in hover down, that's fine. The wild 3D videos you see online are not from people with a year or less in the hobby. The sim will allow you to progress faster, but you will still have to build up the muscle memory for each new maneuver and that's where the sim excels- just push the reset button and you're back flying with no down time for parts, building and setup. Good luck with the 600, you're going to have a blast!
