Thanks alot guys for answering my questions. The fuel is inside the flight box, away from light in a jug that is glazed over. provides double protections. I have ordered 4 cases of fuel from my LHS. Will keep the unopened cases in a dark room.

Would it be best to close off the jug after each flying session with a screw on top rather than leaving in the top with the fuel lines fitted to the top to prevent moisture from contaminating the fuel ? I do this just be safe.

Thanks again

Cary
