I'd be interested to see results from the GSU connected as well, maybe include thrust measurements and the EGT's at those measurements.

In full scale jets - older designs, smaller engines - we can sometimes see certain ambient temps bringing the engine to EGT limits before being able to set takeoff thrust, depending on the health of the engine. 97 degrees is cetainly not an extreme temp, I've seen this at the 120 degree mark and such.

With model engines I would not be suprised to see something like full thrust being limited by EGT, rather than the engine being dynamically limited to those thrust levels based on density altitude. But I don't have lots of experience running my model engines in test conditions like this, I'll be the boys at JC would know with all sorts of test cell runs over the years. In a Jet Cat, for expample, if the EGT max limit is reached momentarily and can be controlled by the ECU, will the engine thrust setting simply be limited / brought back, or will a flameout be commanded by the ECU.. I wonder.

I'm sure the pipe is at play on those readings too as said above.
