If the E-flite meter you purchased is [link=http://www.horizonhobby.com/Products/Default.aspx?ProdID=EFLA110]this one[/link], it has one disadvantage (in my opinion) compared to some other power meters. The E-flite displays only one electrical value (volts, amps, watts, etc.) at a time. To see all of the readings, you must switch the display from one value to the next. That sounds easy enough, but it can be challenging when you are trying to write down the values, switch the display from one screen to the next, and do all of of this while your motor is running at full throttle.

Personally, I prefer a meter that displays all of the parameters at the same time, such as the [link=http://www.astroflight.com/store/store-type-tem.html?item=products:af-101n]Astro[/link] or the [link=http://www.bphobbies.com/view.asp?id=A0320107&pid=U054250&img=l]Watt's Up[/link]. I find this type of meter much more convenient to use. As for cost, they are about the same as the E-flite. My own meter is an Astro.
