In my review of the Eachine Falcon 210, I concluded that it had a terrible camera and ESCs, and that you should not buy it. If you already have bought it, though, here are some tips to slightly improve it. I still say that the single biggest thing you could do to improve it is put some good ESCs on it. The next biggest thing you can do is put a decent camera on it. The camera side-plates seem to have mounting holes for an 1177 style camera, which suggests it should be possible to use one, although you would probably have to change out the plug.
