I got the Blade Chroma for Christmas this year. Woo Hoo! For what the Chroma costs, there is no way I could build a scratch build a multirotor to do all this thing is capable of doing and all the features it has. Next is to test the stability of the airframe. It appears to be Very stable. I'll hard mount a small camera on top of the fuselage to see just how stable it truly is. Just from watching it hover and fly, I'm sure it is quite stable.
