Hi Marcus,
I've taken some pictures from the bottom side. I used an epoxy chassis from
Mikromodellbau.de and added the original details under that chassis. The front axle is from "Faller car system", the swinging rear axle is from Mikromodellbau.de. The on/off switch is hidden under the exhaust, the charging connector is on the opposite side (with the three holes).
... strange, I can attach only one pic to the posting ... have to make one Posting for each picture
EDIT: finally the upload worked
