It is very good for nitro or sct 4x4. For mod buggy its kinda useless, those motors run cool anyway. In 17.5 where you might be pushing temps, it can be usefull. I have a MT4, but honestly, I like like using and external sensor with a RM 2wd buggy. If I go MM, I will probably use the prob. Less airflow on the mid motor and easier to use the prob.
