Hi,
Keep using the sim. I've been practicing on one for about 6-8 weeks. Went up for the first time for real today

....and I believe the practice was invaluable as I landed on my own without a scratch, on my second time in the air (with an intructor and buddy-box of course). Just keep at it

I was the same way with the sim, now I can put it down acurately on it almost all the time. But it definately helped when it was time for the real deal
Have fun
Adam
