it depends on the indiviual, instructor, and flight training time.
and if your plane still stays in one piece.lol
size of your fleet or how deep your pocket is
i suggest a duraplane....

I had a good instructor.
safty first alway. did everything by the book almost.
preflight checks and ect..

flying a straight line , procedure turns, and slower speed.
if anything..you pushed me to make progress and practice.
mastering differnent maneuvers 2-3 mistake high and lowering
the altitute. 3 months before i soloed. after that..i was putting in
over 30 flights a week, flying everyday after work.

there's peaple that's been flying for over six months that havn't
mastered these basic maneuvers. As long as they have an instructors
standing next to them , i don't mine.

then there'e those who's getting ahead of themselves, soloing.
i hate it when they decide to fly there planes when mine is already
in the air. i had my head buzzed, planes almost take my legs off,
planes flies right into my flight path when i'm in the middle of aerobics
manevers, planes almost take out my parked fleet.
