I'm done. Dyno's are useless. Bomb-Proof Has Spoken.

Forgive me for trying to help you make something useful.

All due respect BP, all I see is you disagreeing with all my points, even after I've acknowledged your valuable / valid points.

How is that helpful?

Simply put,

Dyno's exist because they provide useful info. PERIOD. They are not the answer to everything and will not solve the world's problems. I know this. But they provide useful info.

Batteries could be used as a power supply. We could do that. Pre-programmed "throttle pulse profiles" could be programmed in and if the motor is under load (or if we built a RC chassis dyno) would give closer to real world performance estimates.

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...
