http://www.horizonhobby.com/Products...rodID=EFLM1915 for the motor mount, they had it in stock at my LHS, I'm getting a thunder power 3s 1320 mah LiPo for mine, my little 640 can't handle it. Basically any good quality LiPo that's about 1500 mah should work, just make sure it can put out the amperage required, like the pack I'm getting can put out 17A continous, 20A burst, That's more than enough for that motor, or should be. Also, go ahead and use the stock prop with that motor, you need to reem the inside of the prop a little to get it to fit onto the prop adapter that comes with that motor, and you may need to fiddle with the prop adapter itself if you've never used one before. I'll let you guys know when I get some additional flight time, and how it goes.
