All I can say is WOW! Talk about waking up your Lama!
I had been running with standard blades on 'expert' settings and with the flybar weights removed, and it was still rather sluggish.
Not any more! With the carbon fiber blades it has a lot more power, and is MUCH more sensitive to stick input. But still very stable in a hover. Best of both worlds! Much more like a 'real' r/c heli.
The only downside I can see is that with the foam blades if you run it into the furniture the blades will break and that's it, I have a feeling that now the blades will be fine and something else might go. But I think it's worth it for the extra oomph!
I got them here on a tip from a RR post: http://www.jutstar.com
He didn't have them listed on his web site, but he responded quickly to an email and I had them a few days later. (He's in Canada)
