Much of this is hear-say so may not be reliable. From memory, the original PT-19 was powered by the old Babe Bee which had a single bypass. Many people started flying CL with one of these. All of Cox's RTF CL planes were powered by the Babe Bee. This was before they came out with "product " engines. Later ones had a product engine and a plastic molded tank (I THINK). The last ones were just a bit lighter and sported a "Sure Start" product engine that has twin bypasses and a choke tube for easier starting. Reports say the new one flys better than the old one.

I have never had a PT-19 so this is from memories of seeing the old ones, and reading stuff on the boards about the new ones. I would say, if it is a new one, fly it. If it is an old one, I would suggest putting it on one of the auction sites so some collector can drool over it.
