I tend to agree. Dynos won't be 100% accurate because there are other factors in a real system, but at least you can compare the numbers to see the relative performace difference with BL vs Nitro, or setup changes.

As far as the power supply used; I'd just use a typical power source found in a typical setup; lipos or NiMH cells. I wouldn't use a power supply without taking other precautions because the back EMF can damage the regulator circuits unless measures are taken. Other than that, a power supply could be a good idea providing it had similar load characteristics as a good set of batteries. Meaning: it should NOT be tightly regulated. You want the output voltage to fall somewhat with high loads to simulate a typical battery setup. This could be easily done with a linear regulator circuit with loose regulation. Losses would be kinda high, but we aren't concerned about efficiency here.

Just my $0.02...
