Hi everybody newby here! I bought a new arc air pro set(cost a small fortune)yesterday and set it up and got it all working but the controllers are really sensitive (only requiring the lightest touch)and as a result the cars keep flying off the track at pretty much every corner! Is there something I need to do to stop this happening? I did read on here that I need to true the tyres and also use some wd40 to make the track more grippy, should i need to do this with a new set? And if so how would i do this, true the tyres that is? I also read that maybe i should weight the cars with some kind of weights, again should i need to do this with a new set? Any help/advice would be greatly appreciated. Nick.
