I'd only add that 50 flights on a trainer isn't all that much in the way of preparation for a second plane, particularly something like a Phantasy.

You never mentioned aerobatics as being something you could do with the PT, so maybe you DO need more time with it. And yes, I could fly the trainer inverted 20 feet off the deck, but I have 9 years with a myriad of planes under my belt.

You should at least be comfortable with most aerobatics on the PT before you move on. The Aerobat is a good one, as is a 4*, or many others that have been mentioned as second planes.

Good luck,
