I like their plastics, it is much stiffer than any car in the market! It gives the car less tolerance and sharper on corners. Very high fiber composite! Good car!
Thank you for your information ching!so are you using default settings? and by the way did you balan ...
It depends on what you have put onto your car. I.e. different servo, receiver, motor, battery etc has different weight. You have to check it yourself. It is hard to tell you whether u need to put on any weights, as long as both sides are balance then you are fine. Hope this helps
