It took me 13 months and 66 flights on my Superstar to solo. Could I have solo'ed sooner, maybe. But I ran into problems during the training and it was nice to have someone there to help out and talk to. Now when I am on my own, there is not too much that catches me by surprise. Take your time and progress at your own pace. Get as much time under an instructor as you can. This way they know how you fly and when they let you go they know you can be trusted. I would feel much more comfortable with a person that has both quality and quantity flight time under an instructor than the "I solo'ed on my 5 flight" quickies.

Good Luck!
