There isn't a bad question...that is what the forum is all about......but at times people ask questions like the amp draw of a glow plug...that really has very little to do with operating an airplane....not saying your question had no merit......

You were basing your question off of past experience......most of us, including me, has never taken a temp reading...can a temp reading be useful? I suppose so if you have a problem and know the correct temp as a base data.....

In all my years of flying...I've only seen one engine fail due to over temp...on a helicopter.....where the cooling airflow is limited....There was no smoke and he was using 30% nitro......

Like I said IMHO I wouldn't get too wraped up in temps....more power to those that do...I just find that info is not that useful to me

A good tune by ear on the ground...and a good smoke trail while airborne has worked for me

GOOD FLYIN
