Darren,
If you read my post above, you'll see that my club requires a lot more. Not that being able to take off and land is insufficient for soloing, but we prefer to have better flyers before they're on their own.
All I was getting at is, soloing on the fifth flight or fifteenth really doesn't matter. But it may also depend on what's required to solo. Would you have met our requirements on your fifth flight?
