RE: succesfull first flights
I want to congratulate you on your first solo flight.
I know you didn't ask, but I would take the advice of the instructor.
I know you are impatient, but I would wait until he is comfortable enough to let you fly solo.
While you may be competent and nothing bad may happen, I have seen many people who do good with the instructor only to crash later because they think they are ready to fly alone.
