With the new coupling housing, it is possible to mount brush
motors of the 400 speed class with a pitch circle of 16 mm. Likewise,
the Graupner Brushless Speed motors can be mounted. The base is such
that even a outrunner motor roams anywhere.
Holes: 16 mm bolt circle horizontally. Long holes vertical.
The mounting holes for the base can be made by yourself. Alternatively, it can also be glued.
