Crash, looking great. It's going to be a head turner with the transparent covering. The only prob with the fuel usually is the nitro evaporates out, but I often fly without nitro and still get great results. As long as you are getting sufficient RPM I wouldn't worry about it. I've used 4 year old fuel in an old beater plane with no ill affects, and it was stored in an uninsulated garage through Iowa summers and winters.
