It is starting to get hot here in Kuwait as the air temperature ranges between 40-43 C as highs and 28-31 C as lows.

Many guys here already ended their season as they think it is getting too hot to run gas engines especially for 3d flying.

Is there such a thing as maximum weather temp to run gas engines safely without damaging the engine?


TIA

I have hovered here in Nevada when it was in the high ninety's, but Im sure it gets much hotter there. When it gets abobe one hundred, (40 degrees C) just stay away from the extended hovers. It might pay to get a temperature gun and keep an eye on your engine temp.

this feels comforting for someone who is addicted to flying and keeps resisting ending the season

These days, before the real hot summer starts here, some of us try to reach the runway at dawn, and stay for 2-3 hours (from 5 am until 8 am) or until the temp reaches 35 C (95 F).

Last week I was flying while the temp was around 34 C (included some hovering) , and as soon as I landed and shut off the engine, I used a temp gauge on the ground pointing to between the second and third cyl fins, and engine temp was around 85 C but kept going higher until it reached 95 C. I am guessing this is considered safe! I am using a louver in my yak to optimise the air flow.
