I've had this thing for a bit and finally got to try it out today. The small disc which has the manual won't work in a practically new Win7 machine as the disc drive won't accept what comes with the meter. Trying to individually access files leads you to a website to download the USB interface stuff only it's in a .rav file or something like that which is compressed and Windows cannot open the thing.
While this thing may be capable of a lot of functions, it's worthless without a computer to readout what it's got and I don't know about you, but I do not take a computer flying.
Lastly, the readout is blue and so small as to be worthless, or at least it is to a 62 yr. old guy with bifocals.
The main reason I purchased the Powerlog 6S was to monitor the current draw on the speed control. I don't like doing the math, even though I use math in my job for calulating current flow, resistance and voltage.
When I am out flying, I find it quicker to plug in the Powerlog and test current flow while my planes are static. I can then adjust my prop size on the ground to get the most out of my power system, without over-taxing, ie. overheating the speed control.
I have not scratched the surface of all the features on this unit. Looking forward to doing that, at my leasure. But my main emphasis is on flying. I try to keep things quick and simple, and this unit has filled the bill.
Only downside is the screen is a little hard to see in some lighting conditions. Could be LCD backlit, like my Fluke.
Aside from that, a great bargain to help protect my equipment.
ProgressiveRC Comment: Glad you are enjoying the flexibility of this electric swiss army knife. One small correction - the screen IS backlit (like my Fluke). Okay, maybe not as bright as my green on black Fluke screen, but the backlighting on the PowerLog does help immensely :).
