I went solo at just over 21 hours if i remember without looking at my logbook.
I was 21 when i was learning and was flying almost everyday until i took my test 4 weeks after starting (in the UK!!)
I thought being young, learning intensively and having a fair few hours all over the place before hand would put me in good stead for a minimum time to solo.
I was wrong and it was hearing about all these very low 'typical' times that made me feel behind and probably got to my subconscience and consequently take longer. Of course at the time i didnt take into account that i was completing GH exercises that could have been done after the solo.
So despite all this waffling, my point is although it bugged me at the time, i passed after 18 days in just over 50 hours. Now it means nothing, so for those that are/were concerned, it really does have no affect on your overall flying ability. That aside it is an amazing feeling and will never forget the day (5 or 50 hours regardless)
