I LOVE my new Blade 450 3D BNF. Running a DX7 TX and Hyperion 2200mAh 35C batteries. It was put together and set up very well. I pretty much tore it down before flying to inspect everything and it was lock-tited, lubed and greased in all the right spots. Mechanical set-up was dead on with perfect zero degrees pitch at center stick. I just needed one turn on a grip link to get perfect blade tracking. Nice and smooth hover, but still fast! A little "soft" in hard core 3D for my liking, but that was easily fixed with TX setup/programming. I started with the settings for Advanced and went from there. Best "buy and fly" heli I've ever owned and I've had a few over the years. The Blade stuff is pretty good in my experience with an mSR, mCP X and, now, the Blade 450. Glad I didn't waste money on the 120SR, CP Pro, SR, Blade 400, etc.
