I have owned a Caliber 30 for a few months and have had about 30 good flights, until recently. The first flight of the day everything runs great with plenty of power, but after refueling for the second flight it has no power. It is harder to spool up, and barely gets off the ground. The first thing that i then do is lean out the engine, engine seems to run hotter when doing that but has tons of power. Again after landing and refueling for the third flight it has no power, can't even get it off the ground. I have replaced the glow plug from an os #3 to an os #8 and all of the fuel line. I am also using coolpower 15%. Any ideas anyone ???
