RE: How to hook up my ESC to my brushless motor?
Hi Andy -
If you use the $3 wattmeter setup, you can still use the meter for other purposes. Unplug the connectors for the R/C battery and plug in the meter's regular test leads, and you can use the meter for conventional purposes. However, if you get one of those very inexpensive meters, the cost is so low that it makes sense to dedicate it to R/C usage. That way, it's always ready to go for R/C use.
In the long run, I think you will be much happier with a purpose-built R/C wattmeter that displays both current and voltage at the same time. Something like the [link=http://www.bphobbies.com/view.asp?id=A0320107&pid=U054250&img=l]Watt's Up meter[/link] is what you want. There are many brands available; I posted the Watt's Up link only because it includes a nice photo of the meter's display.
Having used both the $3 solution and a purpose-built wattmeter, I much prefer the purpose-built wattmeter.
