The videos posted here rised up my expectations but I remember I had the same expectations before buying MK electronics. Especially videos from quadrocopter.us showed us that flying these birds is super easy. But, MK electronics is about the software trimming. I don't even mention about hours spent for soldering needed.
What I liked about DJI W-M is the compact design and no solder work. I always check the solders couple of times before MK flights, which will make me sick of the idea of "what will happen a solder comes loose??".
I am impressed by the videos, I needed an extra flight controller and I choosed DJI W-M because the price was not higher than MK kit.
We'll see how it will perform
Hopefully equal or better than MK
