This is a great DIY Square Tube 90Deg motor mount for 12mm tubes, it comes with all necessary hardware for mounting and can accommodate a large range of motors.
Motor mounting: Slots from 28mm to 11mm
Perfect for homamade projects of quads and tricopters.I ordered this and got something like the 0-degree one (http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=40669), where the shaft axis is parallel to the motor mount's surface. It's not exactly the same, with slightly different flange, different packaging and correct barcode, but definitely wrong item according to the picture on this page. Looking at the other reviews I realized I'm not alone. Luck for me I can actually find use for these 0-degree mounts, and I can't exact complain about the price or the quality; but this doesn't change the fact that I didn't get the 90-degree mounts and my project is put on hold because of this.Wrong tem.
It is not a 90 deg motor mount.
Ordered 2 times and HK sent me a 0 deg motor mount.
