32 hours to first solo, R22.
It's interesting to see (but not exactly a suprise) that there are so many of pitfalls for the student to watch out for during the flight training process. I made most of the mistakes that you can make on my way to first solo, most of which have been mentiontioned above.
Irregular training is a big one - sometimes once a week, sometimes once a fortnight and sometimes, for various reasons (weather being the main offender) much longer.
Consistency of instruction and instructor is also an important point. By the time I had 25 hours, I had flown with 5 different instructors and each one approaches things differently. I also did an awful lot of hours with low time instructors (a couple who had only just qualified) who ofcourse weren't authorised to send me solo. Trusting and getting along with the instructor is pretty important too. One of my instructors was a very experienced, high timer but about as grumpy and impatient as they come.
But in the long run ....... who cares?
