Astro Flight needs to get off their duff and start supplying Super Whatt Meters. I've had one on back order since April through a on-line store. That's ridiculous. I sent Astro Flight a email asking them when they would be available, and they said they were busy making chargers and would jump on the meters soon. That was a month ago. To anyone that may be waiting for one, I offer a alternative from Cermark. This one measures amps and volts, and you can do the math to find watts easily. Just multiply volts times amps to find power in watts. Cermark's is only $39.95. I just hope the quality is there, because I've heard so many good things about the Whatt Meter, but I just can't wait any longer for one. Here's a link to Cermark's unit:

Jesse, the picture and the specs on that Cermark unit are identical to the meter I have. Mine is labelled "MPI"- Maxx Products?. But it looks exactly the same. Mine was only $30 at the LHS. Despite the fact that you have to add your own battery and ESC connectors, (and maybe that's a plus; you don't have to remove connectors you'll never use first) it's been very handy, seems accurate, and it's given me a much better idea of what's going on (bad pun!) in my power systems. Now that I'm taking the brushless plunge, some sort of ammeter is essential.

OK, time for the I'm stupid question.

I picked up an MPI MX 8100 DC Amp Meter (looks exactly like the ones posted above) at our local Electric Fly today, hooked up the connectors, and try it out. Put the switch on V and it seems to work fine, voltages jive with the multimeter I've got, but when I flip to A, it just keeps counting/varying, even w/o the motor running it reads 30-40 or so. I'm confused, do I have to leave it in a A for a while for it to figure out what the current is? Just seems really odd, and I'd like to know if I should try and take it back.

Is there more than one model of Astro Flight meter? Most sites I see only have a non "Super" meter_bob

Yes, there are two meter's made by AF. The Micro Meter and the Super Whattmeter. The micro has higher resolution at the expense of less "range" so-to-speak. Get the one that best fits your needs. Most of my stuff is in the 12-15 amp range, so I use a Super.

Astro Flight's online store is [link=http://www.astroflight.com/e/env/0001JhIQb2ObQwsUgk0y8L3/store/astro-store.html?link=/store/store-Chargers.html]here[/link].
