Okay, I tested the stock TRX 1200 pack by itself using the 23T "speed" pinion.
I hammered it the whole time doing full speed passes, wheelies, and full throttle grass runs. Runtime was just over 10 minutes before it slowed down.
Motor temp

In the white Excel graph, the Volt Count indicates how many data points were found at any given Amp value. By this you can see that it is rarely above 30A, and spends most of the time under 15A when used with the stock 6cell NiMH battery alone.
