I agree with this in general, but I wouldn't willingly try to teach someone to drive in an F-1 car. Those who make it are probably darned good, but the percentages are not good. Once you've learned in a trainer then go push yourself and expand your envelope. One of the most fun planes I've ver flown was an Evektor Sportstar. (I don't have a lot of types under my belt!) I do have ambition to expand my list in the hopefully near future.
