The problem with small frames is weight and balance. Carbon fiber is heavier than plastic. And the closer the props are to each other, the more sensitive the roll and pitch become as well on a smaller quad, unless you are using 3s or better, it will feel like a slug compared to some of the cheap plastic micro's. They are a pita to fly. Twitchy, under powered and will roll on you in less than a heart beat.
If you want a micro, get a cheap plastic one like the Hubsan or something similar. Something with a 5.8 vtx and adjustable video channels. Can spend less than 100 bucks and find something that will fly circles around your frog.
Honestly, the only thing those carbon fiber micros are good for is teaching you how to build a bigger one. And they are not that much cheaper. Get the Eachine Wizard instead. Or go plastic. The wizard flies great right out of the box.
