I have Realfligh and I think it's excellent. I highly recommend it, and the tutorial should do you just fine. However, don't think that you don't need an instructor in real life once you've gotten the hang of Realflight. That's a huge mistake. There is so much an instructor can tell you that RF can't. Plus an instructor will save your behind when you screw up after that gust of very real wind comes along, and you plane is spiraling straight at you and you lose control inputs, and it hits you in the face, and you DIE!!! THE END IS COMING!!

Ahem, sorry about that....
