Cool fuel.

I got the bright idea to cool the fuel for the planes before going to the dog track. I put the can in an ice chest. I think the cool fuel helped the engine runs. I mentioned this on a forum and some have tried it with no change that they could figure. One guy in Brazil does keep his fuel in an insulated case to keep the temp. stable. I cut some plastic foam strips and glued them to the fuel can for insulation. Can't hurt. The plane did fly the best it has with the cool fuel.
