Ability to charge them at higher rates, better discharge rate and generally less prone to puffing over time (this last one is pure speculation from my side) is the reason. But - that's just my view I found Flightmax (20C) batteries losing their original power after 20 cycles, while nanotech are still holding and I have them around just that number of cycles...

When I put CF blades on my bird I started damaging blade grips. Though having said that when I put CF blades on I was at a stage where my crashing had become inevitably more spectacular.
True - if you have cheap blades to take all the power - fine. In my time I went for strengthening everything and ended up with main shaft/main gear (and a link or two) to be the weakest parts. But that was on MT...

Don't know. I'm talking from perspective of beginner switching from original MT (OBL) motor to Scorpion and how night and day it sounded. It gave me far more confidence knowing that it won't be easily bogged when trying to wrestle it off gravity and inevitable. And it worked - it managed to save my day more than once. And it is, so far see as, one of the best value for money motor...

Good servos, powerful motor and ESC that can handle it and good tail servo/gyro combination are always worth - no matter what frame you're putting it to. Power to save you from crazy situations (you don't want to crash because you were bad at collective and it started heading to the earth and you can make motor to pull it out of it), servos to survive crashes and sustain torque needed for head (today most servos can do it relatively easily - before it was bad idea going with 'cheap' hs55 servos instead of 65mg...) and tail combination to keep the tail in right place when you suddenly bog it...

That's how I see it... It worked for me so far!
