Far from it. First you have to figure out a way to mount it. Then the plugs are different on the servos. I actually soldered in new pigtails on my servos. Then you need a dual ESC with a 5V BEC since the servos can not handle more than that and the uBrain has a 4.7V minimum. Well the servos might be able to handle 5.5V but that would be right on the edge. I'm pretty sure that's absolute maximum for the regulators used on the the servos. Then the whole mod adds a few grams of weight, turned out to be 5g for me. Though if you're willing to go through the gyrations there's a huge difference between Blade's controller and a fully adjustable flybarless controller like the bigger models fly. You can also use much more reliable and efficient ESCs compared to the ones on the 3-in-1 board. Then you'll want outrunners on the main and tail. It's actually quite a can of worms to open, but you'll end up with a first class heli.
