I hope the Esky 3900kv will fit ok, as it looks like it's a bit larger diameter (being an outrunner motor) than the stock motor. They're selling it as a HBK2 motor upgrade, so hopefully it won't be a problem. Darn, I'm stuck flying the Lama for a few days til the new motor shows up.
Esky really needs to do something about the crappy stock motors on these things. My brother, Dad, and I all got HBK2's for Christmas. I probably should have ordered all of us the new motors...
actually you probably should have ordered motors for everyone... also, the 3900 will drop right in, make sure you get a pinion with the motor as well.... and i hope you got a brushless esc with it because you can't use the stock brushed esc with a brushless motor.
