Just thought I would post my mini review of this esc. I had bought a Carboncore X500 quad frame for a smaller ship just to fly around but was having a hard time finding a way to install everything clean. Ordered one of these and it fit perfect between the top and bottom plate with plenty of wire lead to reach the motors with the wires ran through the arms. Had its maiden flight this evening and I have to say it works great and makes for a clean install on smaller quads no need for distribution board. I'm running Ipower 2217Q and the motors and the esc barely got warm after flying a 4000mah 3s pack. Naza controller. I am no way affiliated with any of the above just a happy user.
