I have a ryobi 31cc in my Dynaflight PT 19 and it flies great. I bought it at the huntsville swap meet, it has conversion parts from Jagg engines. I don't know if Jagg converted it or someone just used Jagg parts. It will start by hand, but is real hard to start that way. It starts easy with a starter. It turns about 7200rpm with a 16 x 8 prop. It pulls the 89" PT 19 great, but is not a speeder by any means. It is my first gas engine and I would definatly buy another.
