www.rcdeskpilot.com is a free sim. It's for Windows only. I use it and it's okay. I have yet to try it with the wind on, but sims are for two things: 1) so you know which stick does what. You can grow muscle memory with the Tx. 2) so you don't turn the wrong way. So when the plane is coming towards you, you don't turn right when you meant to turn left. Really any sim will help you with this and the quality doesn't really matter. No sim can replace real world experience, it's just a tool to make it an easier transition and to learn a few things.
I know Hobby King sells a crappy cheap Sim package that is a USB game controller that could never be used as an actual Tx, which almost makes it a waste of money. A better way to go, if you're going to scratch build, is to buy the Tx you want, and if that Tx can't be hooked up to a computer, then get this: http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=43335 Most Txs CAN be hooked up to a computer without that, but the $30 Hobby King Tx can't.
I think with scratch building you're going to end up spending about $150 for everything. And that's buying the cheapest Tx they make. Scratch building has its problems, mainly that you're not going to build your first plane that well and you can never fly a crappy plane well. Plus you can't fly well when you first start, so it can be a disaster. But it's cheap. You can build whatever you want and it's cheap.
Before I get into too much more, where do you live? I want to know if I can/should recommend things that are only available in the USA.
I know this is late, but...
Rc desk pilot is a great Sim, except for flying wings, they don't work well. And yes it is possible to fly with a cheapo two stick game controller. I learned basic 3d with the 3d plane and a game pad. Wind on things get interesting fast, I like the wind, as you can slope soar using it. I whole hearted lay recommend this as a first Sim.
Also, about the Bixler. Get it. Now. It flies better than the EZ star, hawk sky, floater jet or EZ star 2 all of which I have flown, (though I haven't bought the EZ star 2) It has survived two spectacular crashes and still flies great.
