I too am sorry to hear about your fault. It isn't your instructors fault nor yours, it is a combination. Again, Crashes happen don't worry about it. If you can fly the pattern and fly figure eights and straight and level, you were more than ready to take off, so your instructor wasn't trying to rush, you were just very good. The lt-40s are great planes from what i have seen (never flown a 40), I have however flown an lt-25 and it is a very fun plane. Have fun and don't feel discouraged.
