I'm using the 2830/1095. I don't know if I've got the KV right. Check out the thread on RCgroups. You'll get a lot more response over there. THe guy that used the 2816 said it took at least 1/2 altitude to hold altitude and the motor came off so hot he couldn't touch it. You really need at least 250 watts to have a good KM setup. THe torque and Hacker outrunners can do this easilly and so can the 2025, heck, even though it's heavy the Park 480 can too. However, the 2015 and 2816 can't.
