Hey, everyone. I'm sitting here in a shopping cart with my P2, a spare battery, and ready to buy! I was looking a the T-motor Antigravity upgrade, and wondering if anyone can share some insight on them. How's the performance difference, battery time? I realize not many people have done any upgrades on the P2 yet, but I figured I'd ask. I can always do it later, but if they are a good upgrade for the P2, I'd rather order them now with the quad. Thanks in advance!
