They have very fast shipping. I've placed 2 orders with them so far and both arrived within days. Now to the ESC. I have an older M2 that did not have TALY (Torque Assisted Left Yaw). I bought this new version plus the flight controller so I could have this. Installation was a breeze: plug-n-play. I still have to do the hover routine to calibrate the FC but that shouldn't be a problem as OMP has a video on how to do this.
