I'll do a run without the heat sink when I can and post the results.

BryFlyGuy67:
I'm not sure what you meant by "estimate the net heat contribution of the motors versus the 3-in-1. ". Can you explain that a little more?

rweatherford:
That was one of the things I set out to do, look at the power each set of motors needed to hover the heli, to see if the 180's would give longer run time. But since the motors are controlled via PWM, that makes power hard to calculate. I can measure the percentage of on vs off time and tell if one set of motors is using less power than the other, but converting it into watts is more difficult.
What I meant was that there are really two major heat contributors inside the "canopy": the motors and the ESC / 3-in-1. I would be curious as to the relative heat contributions from each component, though this would be diffcult to measure.

Does that make sense?
