Is this the normal heat level for a RC 350 on a normal day?

 

Looks like mine. I don't know what temp it runs at but that's what the gauge reads.

 

That gauge in most modern cars is essentially a warning light. The software pegs the meter dead center once the car is warmed up and operating within acceptable temperature parameters. In other words it doesn’t show temperature but just if it’s cold, warming up, at acceptable temperature, or overheating.

So yes, that’s where the meter should be but it’s not telling you much.
