What is the practical upper limit (if any) on temperature for TappingMode with a standard TESPA or RTESPA probe?
We us a thermal accessory that can heat a sample to ~250C. The sample heater can be used with a cantilever holder that will heat the probe to the same temperature. Usually large temperature steps require a re-tune of the lever as the resonance shifts with temperature. The probes and certain samples could probably tolerate much higher temperatures but the scanner might be at risk.
I've gone up to as high as 270C (and 350C in Vacuum) without a problem.

How do you manage the drift in the image at these temperatures?
Ze'ev.
There's no doubt that as the temperature changes things will shift around. For xy drift a period of time may be required for the sample stabalize at the new temperature. Typically the probe is withdrawn from the surface while the temperature is ramping. In tapping mode large temperature changes cause a shift in resonance that requires retuning the cantilever. The method used to hold the sample down is also important. For instance "sticky dots" would not be a good method for sample mounting with heating experiments. High temperature epoxy is a better choice.
