I appreciate that you see the advantages of this type of testing. I also appreciate your comment about keeping the dialog constructive. I believe if we work together on this, simulation testing can add a valuable tool in comparing all the different aftermarket products out there. Rotor blades are a good example of this.

I think you provided the puzzle piece we are looking for when you mentioned the 4 in 1 output being PWM. My understanding was that the output was variable voltage: that's why I went with the power supplies to maintain constant voltage. The fact that the output is PWM completely changes things. I will have to modify my setup to use the 4 in 1 to provide speed control. I can monitor the pulse width with an oscilloscope to maintain a consistant power level to the motors. Once I have more run time on the Extreme motors I will repeat the testing and see how these two changes affect the data. Once we get a correlation we can look at what other tests might be considered useful.
