The other thing I forgot to mention, is that at the bottom of the product pages, people post exactly which models they use the equipment in, with which motor/esc/prop/battery combinations, and a lot of them have measured the amp draws. This information was very helpful to me in setting up my first electric, as I was able to compare the size of my plane with a bunch of other real world applications.

I know that you can't believe everything you read, but if enough folks say that they have used it succesfully, I tend to believe them.

Good luck
