ummm, if we're talking student training....despite the costs....there is no substitute for wind tunnel flying.  
  i payed 100 bucks or so for the wind tunnel and pigeon forge TN and i blazed through AFF in 7 jumps.
 it's difficult to balance on the wind tunnel wind at first but if you have a "coach"  there, you will learn alot.  
  blue ones!!!! "dude, where's my main?"
