Well, I decided that I wasn't going with the standard set up. I don't know why, I just didnt think 250W would be enough for me to grow, and Tower had a pretty good sale going on I got $40 off my entire order with free shipping.

So I went on electrify website and used their calculator and came up with a "sport" system.I purchased a rimfire .10 with45amp ESC(maybe a bit overkill here)and 3200mAh 25c battery and a 10-7 prop. According to thecalculator, I should be able to get about 7min of full throttle flite time. Weshall see.

Grey Beard, I agree. I don't think there is really one right answer to this question. I'm no electrical expert by any means. My head still swims when I try to read all the ins and outs of electical flight. But I think I'm getting a bit of a hang for it as I actually picked out this same system before I looked on the calculator (good possiblity I was lucky). But like I said, we'll see how accurate the calc is.
