TranspOtterNG started with quite alot of CAD work, as the first TranspOtter was build from scratch and therefore had potential for improvement.

The main problem of TranspOtter (1.0) was in the end, that the wooden frame broke. This was caused mainly by weak wood but also by the motor mount. To fix that, we want to use multiplex wood, which is in general much stronger and milled motor mounts instead of the hoverboard frames.
