Aaah. ok.. si it is unique to me.. sorry.. from the answers/solutions/q:s I got missunderstood 'nd thought that some of you guys wasn't using the xspeed motor or the balldiff at all..

on the clubs track we us double stiff carbon plates on the Mini-z's for best grip.. but the problem isn't just on this track though..

if you want to duplicate it yourself, just take you car to a nice wooden, kitchen or stone floor 'nd put the pedal to the metal (hehe, or the finger to the plastic) 'nd whatch the car do those donutsized skidcircles.. this is exactly what happens... only not until you picked up some speed.

My thoughts are still that the R8 chassi is to high in general 'nd to light in the front, when applying throttle the backend of the car should press itself towards the ground 'nd the front (if to light) will raise some, with the higher chassi of the R8 it might wobble some when "airborn" 'nd the diff tries to stabilize the car but doesn't quite pull that off 'nd instead some magic occurs 'nd 520 degrees later the cars stops with the back pointing the wrong way.. interesting theory, right? lol.. lets call Scully 'nd Mulder..

Lornecherry.. don't buy it just yet :)

I'm now actually thinking about getting that USB cable connection 'nd the software to try 'nd see what I can do within the cars cpu's options... well well... got to buy myself a Lotto coupon this weekend to try finanze this car

please tell me what chassis you have 'nd what hopups you've installed on your cars? 'nd if anybody know what rubber they use as stock?

here's a nice list over orginial Hopups 'nd what fits on the different chassis

Got the new parts - no change.. but I think it has something to do with the diff... It might help with a stiffer H-plate - I'll order wun from Ebay.. but I won't use my dnano on the mini-z track any more... :P

thanx for all the tips 'nd ideas
