thanks :-)
when it comes to it, this cars handling is perfect!
it can handle throttle everywhere (which is privilege of 4WD) but i have problems with "flip over" at low speed .... today i figured out that front spring suspension wasn't good.... and i have new tires, so i think about "round off the edge of the wheel" (i used translate.google to write this, so maybe i wrote it wrong).
P.S: Rear suspension is really hard I didn't notice that undertray touches the ground....
and this undertray is perfect because it defends the rear shaft (guys with Xray 2WD cars broke at least one per race... i do not O:-) )
