Have you seen the tiny stock props? I think these motors would be wasted on the stock propellers.
Try APC E 7x5. My guess is that these motors will pull less than 20A each on those props and 3s power.
Keep an eye on your motor temps. If they run hot, prop down a bit.
Wait...does the Easystar II fit a prop with a diameter greater than 6"? I'm only familiar with the old one...so my comment about the stock prop might be off base.
