Xtreem blades!!! OMG! I just installed a set and my heli has never flowen better. Sorry, I'm a little geeked up but after chasing TBE arround for most of 3 weeks here, and now it is 99% gone I couldn't be happier!! I need to do some more adjusting to level the swash ( again ) and perhaps check the 3 in 1 pot, but I was so happy I burned up my battery flying around my way to small living room.
