I quite like this frame and it flies smoothly. The build quality of the parts is very good and everything fits smoothly. My only complaint would be that it's somewhat difficult to find a good spot for the capacitor, but I reverse-mounted the stack and put the cap right behind the camera and it all fits that way. Seems like it should be able to take some heavy abuse with the plate and arm thickness, and I appreciate everything nicely precision cut and drilled.
