Could be. It was 97 yesterday when I flew it. I flew at about the same weather before when the engine behaves.

I test ran today on ground and noticed the hign RPM did not pass 6000 regardless the adjustment on high and plow needles.

The trouble with a gas engine at such a state is that u have at least one week of downtime. The previous checkup with da was about a month ago. Too bad. Do not know if it is a norm for competition engines.
