Just so you know, stuff is happening behind the scenes. I had an outdoor photosession with the challenger and made a lot of beautifull pictures. The car also performed a very successfull test run. And i found out that the gearbox with the lego clutch rings just can't cope with such high torques. The box was constantly jumping out of gear, so i had to hold the gear lever with my hand. The engine has no effort whatsoever pulling the car. We went uphill in second gear, and the engine didn't even slow down.
I will put the pictures online as soon as the problems with the galleries are solved. When i switched the hosting, image uploading suddenly stopped working and we're still investigating why.
