This is the motor mount for my TinyWing project.
You can check it here.
Suggested to be used with this motor
in push style. It can be used for vertical mounting of any 1811 motors (with mounting holes 15mm diagonal) to a horizontal surface.
The wall thickness is 2mm, which makes it strong enough to survive almost any crash, so that you can recycle this part over and over again from crashed planes. But I do hope you never crash. :D
