RE: Debonair Engine
Go for the OS or Thunder Tiger. Since you new at this OS and TT engines give you less hassles. Other engines are great and wonderful have a GMS and Super Tigre but they a bit more twitchy and can have leaks etc... New guy stick to OS and Thunder Tiger...... The Deb does fly with .40 but once again, to learn and have more confidence I would use a .46. It all depends on how windy it is, how heavy your Deb is etc.... Stick to the specs, get someone to help you start and HAVE FUN...
keep em flying,
