Battery-cases / side-guards
The main eyecatchers are the extremely low laydown longtudinal placed battery-packs at each side of the car, being part of the side-guards, securely fastened with a fliptop-lid, for easy and fast battery changes. The weight low in the car and in the right position, well balanced. The Lipo holders comply with ROAR legal packs / dimensions.

Motormount:
The motor is placed in the most optimal position in the car, keeping motor-forces and transmission parts / alignment in mind.  Only one-screw  is needed to secure  the BL motor, in the nicely designed durable machined aluminium motormount. Space for additional motor-cooling available as needed.
The space for the motor allows a maximum motor-length of 70mm, which covers most widely used motors ( except for the truggy / monstertruck motors).
